STORING
If it is necessary to store the unit for a period of time before it is installed, be sure to place the unit in a clean, dry area. To prevent
excessive dust from accumulating on the unit, it is advisable to protect it by replacing it in the original container (if possible). If the
original container is not available it is recommended that all openings that lead internally into the unit are covered so that dust, water or
any other substance cannot enter the internal components of the system. The unit must be handled at all times with the same care you
would give to any piece of precision industrial equipment.
REMOVING THE POWER CONDITIONER FROM PALLET
Please take special care when removing the unit from the pallet. Proper equipment must be used for lifting and moving, and all safety
precautions should be taken. Each unit is bolted to a wooden pallet. In order to properly remove the cabinet from the pallet, all bolts
connecting the unit to the pallet must be removed completely. The unit can then be lifted off the skid using a pallet jack or a fork lift, as
shown below. When lifting the unit off of the pallet, be sure to take proper safety precautions. Serious injury and/or unit damage can
result otherwise.

GENERAL DESCRIPTION
The Series 700A/V-S Power Conditioner is designed to supply reliable, clean regulated power to critical loads. An efficient design with state
of the art micro-processor controlled solid state devices provide immunity to all line disturbances.
The basic design consists of a three phase triple shielded isolation transformer with seven separate voltage taps per phase. Output
regulation is achieved by monitoring the input and automatically switching taps anytime the input line sags or surges. The use of a triple
shielded isolation transformer provides superior common mode and transverse mode noise attenuation. Automatic switching occurs during
current zero allowing noise free switches for both leading and lagging power factor loads that are connected to the Series 700A/V-S.
MONITOR
Monitoring of the Series 700A/V-S is simple, clean and effective. Three green light indicators are utilized to display “POWER ON”
(output line to neutral for each phase) and one red light indicator to display “ALERT”. The “POWER ON” display is connected directly
to the output that indicates the Series 700A/V-S is operating properly with just a quick glance. The “ALERT” display represents an
over-temp problem or output voltage loss (optional) when illuminated, and will shut down the output, but cooling fans remain on. Overtemp thermal sensors are strategically located at critical points on the regulator assemblies and transformer. The main AC input circuit
breaker must be turned off in order to reset the “ALERT” light.
PROTECTION
Protection is accomplished very effectively to minimize failures and the cost of repairs. A total of five major devices protect the Series
700A/V-S.
1. The input is protected with a integrally mounted AC circuit breaker for abnormal current overloads and provides a convenient
means of disconnecting utility power.
As an option the input breaker may be equipped with a shunt trip device that is interfaced with a REMOTE EMERGENCY
POWER OFF PUSH BUTTON. By pressing this button, the input breaker will trip and disable the Series 700A/V-S completely. The
input breaker must be physically reset before unit will turn on again.
2. The main transformer is protected by fuse links connecting the SCR regulators together, and are designed to clear in the event that
two or more SCR’s should fail. This will prevent a transformer tap short and the possibility of transformer failure.
3. (Optional) The output of the Series 700A/V-S is constantly monitored for extreme over and under voltage conditions. This device
monitors each output phase and will electronically disable the Series 700A/V-S when any phase exceeds +10% or -10% of nominal
output voltage.
4. Overtemp sensing devices are mounted at critical points on the SCR regulating assembly and the main transformer. When an
overtemp condition exists the “ALERT” light will illuminate and hold until the overtemp is corrected. There are no automatic shut-off
circuits for the “ALERT” condition. The main AC input breaker must be turned off in order to reset the “ALERT” light.
5. Each output of the Series 700A/V-S is protected with an integrally mounted AC breaker for abnormal current overloads and
provides a convenient means of disconnecting power from the load.

GENERAL DESCRIPTION CONTINUED
OPERATION
The Series 700A/V-S Power Conditioner is operated by simply turning on the main AC input circuit breaker. Each unit is provided with a
bypass switch. This is a no load switch and MUST only be operated when the unit is OFF. The bypass switch should be in the
“NORMAL” position unless a problem occurs with the system. If a problem occurs, turn OFF the main AC circuit breaker and turn the
bypass switch to the “BYPASS” position. Re-energize the system by turning on the AC circuit breaker and contact the Customer
Support Department for repairs.
Any ‘ALERT” condition requires the main AC input breaker to be turned off in order to reset the “ALERT” light.
THEORY OF OPERATION
The Series 700A/V-S Power Line Conditioner provides the triple function of isolation, noise attenuation and voltage regulation. The first two
functions are provided by the power transformer, whereas the third function of voltage regulation is achieved through solid state thyristors
(SCR’s) connected to taps on the power transformer. A microprocessor monitors and controls the overall function of regulating the system.
The power transformer is manufactured with a unique method of shielding which produces very low capacitive coupling between the
primary and secondary. This low coupling provides excellent attenuation of the common-mode noise. In addition, special care is taken in
the design of the transformer to attenuate transverse-mode noise above 1000 Hz.
The power transformer has taps to which solid state switches (SCR’s) are connected.
The voltage regulator incorporated in the Series 700A/V-S Power Line Conditioner is microprocessor controlled to achieve optimum
correction time of input voltage sags and surges. The response time is typically one (1/2) cycle for 100% correction, therefore, a very
smooth switch takes place undetected by computer equipment.
As the input voltage (building power) varies, the voltage available at each tap of the transformer will also change. The amount of variation is
dependent upon the input sag or surge, turns ratio and transformer losses.
By selecting a particular tap voltage, the output can be kept within a tight range. The way in which this is accomplished is that an electronic
control card using a micro-processor continually monitors the input voltage. When a voltage fluctuation occurs, which exceeds the limit of
rated regulation (typically . 2%), the output is switched to another tap, that is within the required range. This “switch” will be made at the
next current zero crossing to allow for both leading and lagging power loads to be connected to the conditioner.

INPUT WIRE SIZE, GROUNDING AND OUTPUT WIRING
NOTE: Refer to the latest edition of The National Electric Code Requirements for over-current protection and wire sizing.
A Conduit should be used for both input and output wiring.
B Input wire size is based on the NEC table 310.16. Specifying not more than 3 connections in a raceway based on an ambient of
30°C and wire rated for 90°C (Note: amperages will need to be adjusted for 40° C ambient applications).
C. Input phase conductors are terminated directly to the input circuit breaker terminals. Wire range:1/0 – 4/0 AWG.
D. Input ground LUG 2/0 AWG.
E. Output is a 4 wire (5 including ground). If four (4) current carrying conductors are used in a raceway the neutral is assumed to be
current carrying and the wire must be de-rated as indicated in table 310.6 on the NEC.
Example:
1. Assume #10 wire max current = 25 Amps.
2. Multiply 25 x .8 = 20
3. 20 Amps is max current for #10 wire in a raceway with 4 conductors.
NOTE: Installation is subject to local codes - verify with a local electrical inspector.
F. All output terminals are copper bus bars w/ two holes. Double bolted lug are recommended. Manufactured by Burndy

BYPASS SWITCH
The manual bypass switch is a break before make switch located on the Series 700A/V-S. The manual bypass switch is used to bypass
all power electronics in case of failure.
NORMAL MODE
With the switch in the normal position, the Series 700A/V-S will provide clean and regulated power to the critical loads. The Series
700A/V-S should have the switch in the normal position unless a failure has occurred.
BYPASS MODE
With the switch in the bypass position, the Series 700A/V-S will provide clean power to the critical loads. In the bypass position, the unit
will not regulate the incoming voltage. The Series 700A/V-S should be placed in the bypass position when a failure of the system has
occurred. This provides the user with some protection until a service technician arrives.
CAUTION
PRIOR TO SWITCHING FROM ONE POSITION TO ANOTHER- TURN OFF THE AC INPUT BREAKER.
REMOTE EMERGENCY POWER OFF (REPO) OPTION
The REPO is operated by a remote push button that when depressed will shunt trip the Series 700A/V-S input breaker and disable the
unit. This option may be added to units in the field.
Contact our Customer Support Department if you wish to add this option. We can be reached at 1.800.882.9110, +1.208.772.8515 or

PREVENTIVE MAINTENANCE
WARNING
DANGER OF ELECTRICAL SHOCK, TURN OFF ALL POWER SUPPLYING THIS EQUIPMENT PRIOR TO
MAINTENANCE.
To ensure longer component life and trouble-free operation, minor preventive maintenance procedures should be performed at regular
intervals, for example once every year. More frequent inspection intervals would be needed for more severe operating conditions and
larger number of hours of continuous operation.
9. Remove front and side panels and at each service inspection any accumulated dust, dirt or foreign particles should be carefully
removed. Special care should be exercised in cleaning the thyristors (SCR’s), heat sinks and the control assembly.
10. Inverse Parallel Silicon Rectifiers (SCR’s) or Thyristors. The silicon controlled rectifiers (SCR’s or Power Mods) usually fail in the
shorted mode. When this happens, normally the fusible link in series with the SCR will be blown open to clear the short and prevent damage to the transformers. If a blown SCR is suspected, contact Transtector for service.
11. A simple performance checklist has been developed for use in maintenance. See “Performance Checklist” and check off items 1-8.
12. After items 1-8 have been checked on the “Performance Checklist”, the next step is to check the operation of the system.
13. Replace front and side panels. Turn unit on with no load. Check item 9 on the “Performance Checklist”.
14. Turn on loads and check items 10-13 off the “Performance Checklist”.

Installation Manual | Power Conditioner for Accuray CyberKnife®
EQUIPMENT REQUIRED
True RMS Digital multimeter, SCR tester, common hand tools, spare parts kit (contact service center at 1-800-882-9110 X 6112).
STEP 1. DISASSEMBLING THE POWER LINE CONDITIONER
A. Turn off the power to the Power Conditioner at its source.
B. Turn off the input circuit breaker on the unit and the output circuit breakers to all loads. (Remove all loads from unit).
C. Remove the front and side covers to the Power Conditioner. Refer to Diagrams in “Appendix A - Cabinet Layout”.
STEP 2. ELECTRICAL CONNECTIONS, FUSES
Refer to Diagrams in “Appendix A - Component Location Diagrams” for component locations.
A. Inspect the unit for proper tightness of all electrical connections, burnt, frayed, broken or loose connections and components in these
areas. Input and output connections, SCR assembly, SCR snubber, output filter assembly, MOVs (metal oxide varistors), circuit boards,
bypass switch and transformer connections.
B. Correct and tighten any loose connections, replace any physically burned or broken components.
C. Check all fuses in system *. Time delay fuses, fan fuses, circuit board fuses, SCR fusible Link wire.
POWER MODULES (SCR’s)
Refer to the diagram below and the diagram in “Appendix A - Heatsink Layout”.
1. Unplug the connections to the control cards Part # 414921 labeled TB1, TB2 and TB3.
2. Disconnect any cooling fans in the unit so your SCR resistance checks are not interfered by fan motor coils. Each power mod
contains 2 inverse parallel SCR’s.

3. Measure the following resistance on each power module. There are 7 per phase or 21 for all three phases. *Refer to the circuit
diagrams received with your unit.
18
Note: When checking the power module assembly, if more than one defective power module is present it will appear as if all the power
modules are defective. If this is the case, the individual power module must be isolated from the power transformer.
4. A. K1-1 to K2-1 thru K1-7 to K2-7=High resistance, 1 Meg Ohm.
B. K1-1 to G1-1 thru K1-7 to G1-7=10 to 90 Ohms.
K1-1 to G2-1 thru K1-7 to G2-7=1 Meg Ohm.
C. K2-1 to G2-2 thru K2-7 to G2-7=10 to 90 Ohms.
K2-1 to G1-1 thru K2-7 to G1-7=1 Meg Ohm.
D. G1-1 to G2-1 thru G1-7 to G2-7=1 Meg Ohm.
5. Replace any defective power mods. This may require removing the shunt and loosening the K1 bus from all the power modules to
get the defective power module out. Use only equivalent hardware and heat sink grease when replacing power modules.
6. If a resistance measure is questionable, a more thorough test will assure an SCR is good or bad by using the following
test procedure.
A. Completely isolate SCR under test by removing all connections to the device.
B. Hook up the following test circuit to each individual SCR.
C. Plug in SCR tester. With Switch #1 open light bulb should be off. If not, replace SCR.
D. Close Switch #1. Light bulb should illuminate to about 3/4 brilliance. If not, replace SCR.
SWITCH
#1
7. Re-assemble the power module assembly, make sure all connections are tight.
CHECK THE SCR SNUBBER CARD
1. Three components make up the SCR snubber. (Resistors, MOVs and Capacitors). Check for open resistors. Check MOVs for
shorts, they should read high resistance when ohm meter is placed across them. Resistance check each capacitor. The DC
resistance across the snubber capacitor should look capacitive-that is high resistance after the meter charges the capacitor. If it
measures open or shorted, replace the snubber card.
2. Re-connect all wires and fans. Double check that all connections are secure. Do not connect TB1, TB2 and TB3 connectors from
the control cards #414921 yet!

Installation Manual | Power Conditioner for Accuray CyberKnife®
CHECK CONTROL CARD AND FILTER CARD
1. Verify input to the Power Conditioner matches the units specification. Also verify correct control board # 414921 jumper setup in
“Appendix A - Control Board Layout”.
2. Turn on AC input breaker to unit.
IMPORTANT: Extreme caution must be taken when measuring voltages on Molex connectors. Do not press meter leads into
connectors or bend connectors back.
3. Measure the following voltages on wires feeding the TB1 Molex connector to the control card on all 3 phases.
Pins 1 & 3 = 4-6 VAC.
NOTE: When the connector is plugged in this voltage is around 3 VAC.
Pins 7 & 8 = 120 VAC
If this voltage is incorrect or not present, then check the fuses associated with the filter card or replace filter card and re-check voltages.
4. Turn main AC circuit breaker off. Plug in connectors TB1 and TB3 ONLY!!! on the control card # 414921 on all 3 phases.
5. Turn main AC on.
NOTE: Refer to “Appendix A - Control Board Layout” for test points and pot locations on control card.
6. Use the following formula to calculate the next adjustments. You must calculate each input phase for each control card or a total of
3 calculations.
A. For phase 1 control card measure AC input at Line 1 to Line 2.
B. For phase 2 control card measure AC input at Line 2 to Line 3.
C. For phase 3 control card measure AC input at Line 1 to Line 3.
FORMULA X
Actual AC Input x 2.59
= Volts DC at TP2
480 (Nominal)
Example: 475 Volts AC Input x 2.59
= 2.56 Volts DC at TP2
480 (Nominal)
7. After calculations are complete, place DC voltmeter on the 20 volt scale and check between TP2 and TP GND on control card.
Adjust pot P1 so meter reads DC level calculated in Step 7 for all three phases.
NOTE: If adjustments in Steps 5 and 6 are not possible, replace control card # 414921 and repeat Steps 5 and 7.
NOTE: Be sure to turn power off when replacing circuit boards.
NOTE: Be sure AC input is stable when making this adjustment. If the input changes, you must recalculate.
NOTE: Output voltage correction is a “stepped correction”, adjusting P1 will not cause a smooth change in output voltage as it is
adjusted.
20
8. Turn the unit off. Plug in TB2 Molex connectors to all the control cards # 414921.
NOTE: P1 pot turned clockwise = decrease in output voltage and counter-clockwise = increase in output voltage. By changing this
adjustment on phase 1 you may see the output voltage change from line to neutral on two phases. It is best to use the procedures
in Steps 1 – 8 for adjusting.

3. Remove all loads from the output of unit under adjustment.
4. Remove both TB2 connectors on all control boards # 414921 (See “Appendix A - Control Board Layout”). Turn power on.
5. Use Formula X to calculate the next adjustments. You must calculate each input phase for each control card or a total of
3 calculations.
A. For phase 1 control card, measure AC input at Line 1 to Line 2.
B. For phase 2 control card, measure AC input at Line 2 to Line 3.
C. For phase 3 control card, measure AC input at Line 1 to Line 3.
FORMULA X
Actual AC Input x 2.59
= Volts DC at TP2
480 (Nominal)
Example: 475 Volts AC Input x 2.59
= 2.56 Volts DC at TP2
480 (Nominal)
NOTE: Be sure AC input is stable when making this adjustment. If the input changes, you must recalculate.
6. After calculations are complete, place DC voltmeter on 20 volt scale and check between TP2 and TP GND on control card. Adjust
pot P1 so the meter reads DC level calculated in Step 5 for all 3 phases.
NOTE: Output voltage correction is a “stepped correction”, adjusting P1 will not cause a smooth change in output voltage as
it is adjusted.
7. Turn unit off and reconnect TB2 connectors on all control boards.
8. Turn unit on, verify output is correct by monitoring the output from each line to neutral. If not, make sure input power is stable and
repeat adjustment procedure.
NOTE: P1 Pot turned clockwise =decrease in output voltage and counter clockwise = increase in output voltage. By changing this
adjustment on 1 phase you may see the output voltage change from line to neutral on 2 phases. It is best to use procedures in
Steps 1-8 when adjusting.
9. Turn the unit off. Plug in TB2 and TB3 molex connectors to the control board.
10. Replace any fuses or wiring that may have been removed for the shutdown circuitry.

SPECIFICATIONS
SCOPE
This specification covers the electrical characteristics of the Transtector Power Conditioner which provides clean regulated power for
the entire Accuray CyberKnife.®
GENERAL
The Power Line Conditioner consists of a front access power cabinet incorporating an all copper, multiple tapped, triple shield isolation/
regulation transformer. The ultra low output impedance of the transformer in conjunction with the electrostatic shields assures precision
hospital grade performance with excellent noise and transient attenuation. Independently controlled inverse parallel electronic switches
for each of the 7 taps per phase provide
tight regulation over a wide input range. Linear devices are used for line synchronization to prevent phase shift errors normally associated with simple CT zero current crossing acquisition. The microprocessor control accurately selects the correct tap to provide line
voltage regulation of + 2.0% typical, correcting for voltage disturbances within one cycle. Digital processing technique provides fast and
accurate regulation without output voltage over or undershoots.
