FLOOR AND ROOM PREPARATION
The Gantry and Table must rest on solid concrete or other basic flooring, not on resilient tile or carpeting which may
slowly yield over a period of time and disturb the Table to Gantry alignment.
The floor structure must be capable of withstanding both the combined weight of the Table and Gantry and the individual area loading of these components. Refer to Section 2, ROOM LAYOUTS, of the Preinstallation manual.
Method and Placement of anchoring must not reduce the structural strength or integrity of the floor.
Refer to Illustration 2–1, TYPICAL ROOM LAYOUT, of the Preinstallation manual when marking the position of the
Gantry and Table on the floor.

INSTALLING ANCHORS USING A ROOM–LAYOUT TEMPLATE
Note
When you use the room–layout template, perform 3-2 Installing Anchors using a room–layout template.
If it does NOT, skip this section and perform section 3-3, Gantry Installation.
The room–layout template (P/N 2322735) (in two pieces; Table Template and Gantry Template) is shipped with the
system. You can use the template to decide the layout of the Gantry and Table so that the anchors can be installed
before positioning the Gantry and Table.
However, if a customer want to check layout with the Gantry and Table positioned in the scan room, anchor procedures
can be performed later after all adjustments will be completed. In this case, skip section 3-2, then go to section 3-3,
Gantry Installation.

Installing Anchors
This anchoring procedure is used for the anchor kit shipped with the system.
Note
The other anchor can also be used, instead of the anchor kit shipped with the system. In this case,
you can use the other anchoring procedures that are not described in this manual, but the minimum
tensile load strength of the anchor MUST meet the specification below.
NOTICE
The minimum Tensile load strength of the anchor must be 13000 N.
1.
Attach a piece of tape to the 12 mm concrete drill bit (2203081: HILTI, TE–CX 12/17 or equivalent) in order to
assure a minimum of 95 mm depth of anchor hole.
Illustration 3–2
12 mm Concrete Drill Bit Preparation
95mm or more
TAPE
2.
Make holes at the anchor position as shown in illustration 3–3, using electric drill with the bit prepared in the
previous step, so that the lower edge of the tape just touch the floor surface. (Also see Illustration 7–6.)
NOTICE
During drilling, always keep the drill bit perpendicular to the floor. With one person drilling
the hole, a second person can visually insure perpendicularity throughout the drilling operation. Clear the hole of debris several times while drilling to prevent the drill bit from binding.
Note
If any obstruction is found under the proper anchoring position, stop drilling and use the alternate
position (see illustration 3–3). Use the alternate positions only in the case where its corresponding
proper position is not possible.

SYSTEM POWER, GROUND AND SIGNAL CABLE CONNECTION
General
This section describes the sequence of system cabling and power–on test. Complete as much of the Contractor
supplied wiring as possible before starting the system cabling. Some Contractor supplied wiring, for example ground
cables, must be pulled along with the system cables. In addition, some raceway work, such as cutting and fitting covers at equipment locations, must be finished after completing the cabling and placing the equipment in position.
All system cables use a system component designator for identification. The end of each system cable has a label
near the connector that identifies the CABLE NUMBER and CONNECTOR NUMBER.

Introduction
WARNING
ELECTROCUTION ! TURN OFF THE SWITCH OF THE POWER DISTRIBUTION BOX AND TAG
IT TO VERIFY THAT ALL POWER IS DISCONNECTED TO THE SYSTEM.
When performing system and ground wiring, ensure that all wiring conforms to the information contained in this manual, in particular to the tables and illustrations contained in this section. The tables in this section list:
D
all contractor supplied cables
D system furnished cables
D GEYMS Supplied cable Part Numbers
D destination connector or socket for the end of each cable
The illustrations provide detailed information on the actual connector and terminal strip locations. Illustrations include :
D System Interconnect Diagram
D OC Cable Connection
D PDU Cable Connection
D Gantry Cable Connection
1
Verify that all ground wiring and other contractor wiring are complete to the point of equipment placement.
2
Check for reasonable cable routing. Don’t forget to leave enough cable take–up for equipment maintenance, etc.
Perform as neatly a job as possible.
Note
Keep signal and control cables away from power cables and power wiring. When laying cables in a
raceway, locate the signal cables in a separate section of the raceway.
3
Verify that both ends of each cable are clean cut and properly located before terminating and connecting them.
4
Ensure that all connections are tight. Use suitable tools. Check and tighten all visible connections, especially
ground connections.
NOTICE
Attach a tie–wrap to each system cable within 30 mm of each terminal end.

GROUP NUMBER–Is a number which is assigned to a group of cables or wires running between two components. It may consist of only one cable, but usually contains more than one power and/or signal cable.
Group numbers are enclosed within a box. (ex; 3 means group number 3.)
CABLE NUMBER–Is a unique number assigned to a single cable within a GROUP NUMBER. All numbered
cables are supplied with the system. Cable numbers are shown as numbers within a circle (ex; 3 means
cable number 3).
ACTUAL LENGTH: total length of wire (see usable length).
USABLE LENGTH: total length of a cable MINUS 1.5 m required for servicing and take up within cabinets
and the PDU.
Note
Actual usable length will depend upon the routing.
Cable Color Label
The color labels are attached to both sides of the system cable. This means that:
D Red – connected to the PDU.
D Yellow – connected to the OC.
D Blue – connected to the Gantry
D None – connected to the Table.

Gantry Anchoring
This anchoring procedure is used for the anchor kit shipped with the system.
Note
The other anchor can also be used, instead of the anchor kit shipped with the system. In this case,
you can use the other anchoring procedures that are not described in this manual, but the minimum
tensile load strength of the anchor MUST meet the specification below.
NOTICE
The minimum Tensile load strength of the anchor must be 13000 N.
1.
Tilt the Gantry to the 30_ FWD position.
2.
Remove the three screws and Gantry bottom cover.

3.
When the room–layout template is used, the anchor bolts have been insatlled. So, tighten the anchor nuts with
the insulating plate and washer at this time. Then go to Table Anchoring.
TORQUE: Approx. 5 N–m (50 kg–cm)
NOTICE
Do not tighten the anchor nuts to the specified torque (49N–m). To over–tighten nuts will
damage the frame of the Gantry and also bring an out–of–level Gantry.

5.
Make holes at the anchor position as shown in illustration 7–3, using electric drill with the bit prepared in the
previous step, so that the lower edge of the tape just touch the floor surface. (Also see Illustration 7–6.)
When making rear holes, the Gantry Rotor section might disturb this work. If it does, rotate the Gantry to make
space.
NOTICE
During drilling, always keep the drill bit perpendicular to the floor. With one person drilling
the hole, a second person can visually insure perpendicularity throughout the drilling operation. Clear the hole of debris several times while drilling to prevent the drill bit from binding.
Note
If any obstruction is found under the proper anchoring position, stop drilling and use the alternate
position (see illustration 7–3). Use the alternate positions only in the case where its corresponding
proper position is not possible.

1.
Remove all the transportation packaging, except dollies, from the gantry.
Note
When the mobile CT system will be transported over 1,600 km (1,000 miles) without scanning, the
brush block must be removed from the Gantry and stored into the special box into which the brush
block has been packed at installation.
Therefore, do NOT discard this special box.
2.
Use the dollies to raise the gantry off the floor, then wipe off the floor surface where the gantry will rest.
3.

There are two types of the slip ring of the Gantry:
D Old Type of Slip ring (ETC)
D New Type of Slip ring (HSDCD)
For the Gantry with ETC slip ring, note the following brush block removal procedures. Refer to the table below for
effectivity.
For the Gantry with HSDCD slip ring, skip “Preparing the Gantry” procedure.
The Gantry with ETC Slip Ring is:
Gantry Part Number
Gantry Serial Number
Total
2249696
682378YM5 – 682380YM1
3 systems
2249696–2
715318YM2 – 715325YM7
8 systems
2247799
696478YM7 – 696480YM3
3 systems
Note: These information are printed on the rating plate located at the Gantry rear base near the breakers.
Also for the Gantry with the effectivity above but which has been replaced with a HSDCD slip ring, skip
“Preparing the Gantry” procedure.
When the mobile CT system will be transported over 1,600 km (1,000 miles) without scanning, remove the brush block
from the Gantry. Then store it into the special box into which the brush block has been packed at installation.
Example 1:
If the customer plans to travel 900 km (600 miles) without scanning on the first day, then travel another 900 km (600
miles) on the second day without scanning.
In this case you must remove the brush block before the travel start on the first day.
Example 2:
In the morning of the first day the customer performs just one axial scan, then travel 1,599 km (999 miles) on that
day. In the morning of the second day the customer performs just one axial scan, then travel 1,599 km (999 miles)
on that day. In the morning of the third day the customer performs just one axial scan, then travel 1,599 km (999 miles)
on that day.
In this case you do not have to remove the brush block.

CLASS 1 EQUIPMENT
Any permanently installed equipment containing operator or patient accessible surfaces must provide backup protection against electric shock,in case the BASIC INSULATION fails. In addition to BASIC INSULATION,Class1 equipment contains a direct connection to a PROTECTIVE(EARTH) CONDUCTOR which prevents shocks when a person
touches a broken piece of equipment or touches two different equipment surfaces simultaneously.
TYPE B EQUIPMENT
CLASS I, II, or III EQUIPMENT or EQUIPMENT with INTERNAL ELECTRICAL POWER SOURCES provide an adequate degree of protection against electric shock arising from (allowable) LEAKAGE CURRENTS or a breakdown
in the reliability of the protective earth connection.
ORDINARY EQUIPMENT
Enclosed EQUIPMENT without protection against the ingress of water.
OPERATION of EQUIPMENT
CONTINUOUS OPERATION WITH INTERMITTENT LOADING.
Operation in which EQUIPMENT is connected continuously to the SUPPLY MAINS.The stated permissible loading
time is so short that the long term on–load operating temperature is not attained.The ensuing interval in loading is,
however, not sufficiently long for cooling down to the long term no–load operating temperature.
EQUIPMENT not suitable for use in the presence of a FLAMMABLE ANESTHETIC MIXTURE WITH AIR or WITH
OXYGEN or NITROUS OXIDE
CLEANING
The system is NOT WATERPROOF. It is NOT designed to protect internal components against the ingress of liquids.Clean external system surfaces(Gantry,table,consoles and accessories)with a soft cloth dipped in hot water and
wrung DAMP/DRY. (NOT dripping!) IF NECESSARY, use only mild (dish washing liquid) soap to remove dirt.
NOTICE
Avoid damage to equipment! Some ”spray and wipe”cleaners etch and permanently cloud
clear plastic surfaces!! Use only warm water and mild liquid soap to clean surfaces.
