Safety Precautions
To reduce the chance of accident, please read the safety precautions very carefully before operation. The
"Caution, Notice, Warning, Danger" in this book do not represent all the safety points to be observed, and are
only supplement to various safety points. Therefore, the installation and operation personnel must be strictly
trained and master the correct operations and all the safety points before actual operation.
When operating Emerson products, the safety rules in the industry, the general safety points and special safety
instructions specified in this book must be strictly observed.
Electrical Safety
I. Hazardous voltage
Danger
Some components of the power system carry hazardous voltage in operation. Direct contact or indirect contact through
moist objects with these components will result in fatal injury.
Safety rules in the industry must be observed when installing the power system. The installation personnel must
be licensed to operate high voltage and AC power.
In operation, the installation personnel are not allowed to wear conductive objects such as watches, bracelets,
bangles, rings.
When water or moisture is found on the Subrack, turn off the power immediately. In moist environment,
precautions must be taken to keep moisture out of the power system.
"Prohibit" warning label must be attached to the switches and buttons that are not permitted to operate during
installation.
Danger
High voltage operation may cause fire and electric shock. The connection and wiring of AC cables must be in compliance
with the local rules and regulations. Only those who are licensed to operate high voltage and AC power can perform high
voltage operations.
II. Tools
Warning
In high voltage and AC operation, special tools must be used. No common or self-carried tools should be used.
III. Thunderstorm
Danger
Never operate on high voltage, AC, iron tower or mast in the thunderstorm.
In thunderstorms, a strong electromagnetic field will be generated in the air. Therefore the equipment should be
well earthed in time to avoid damage by lightning strikes.
IV. ESD
Notice
The static electricity generated by the human body will damage the static sensitive elements on PCBs, such as large-scale
ICs. Before touching any plug-in board, PCB or IC chip, ESD wrist strap must be worn to prevent body static from
damaging the sensitive components. The other end of the ESD wrist strap must be well earthed.
V. Short circuit
Danger
During operation, never short the positive and negative poles of the DC distribution unit of the system or the non-grounding
pole and the earth. The power system is a constant voltage DC power equipment, short circuit will result in equipment
burning and endanger human safety.
Check carefully the polarity of the cable and connection terminal when performing DC live operations.
As the operation space in the DC distribution unit is very tight, please carefully select the operation space.
Never wear a watch, bracelet, bangle, ring, or other conductive objects during operation.
Insulated tools must be used.
In live operation, keep the arm muscle tense, so that when tool connection is loosened, the free movement of
the human body and tool is reduced to a minimum.
VI. Dangerous energy
Warning
240VA, hazardous energy, keep off, no bridge connection. This converter contains outputs exceed 240VA, when installing
into end system care must be taken that the output and appropriate wire may not be touched.
Battery
Danger
Before any operation on battery, read carefully the safety precautions for battery transportation and the correct battery
connection method.
Non-standard operation on the battery will cause danger. In operation, precautions should be taken to prevent
battery short circuit and overflow of electrolyte. The overflow of electrolyte will erode the metal objects and PCBs,
thus causing equipment damage and short circuit of PCBs.
Before any operation on battery, pay attention to the following points:
Remove the watch, bracelet, bangle, ring, and other metal objects on the wrist.
Use special insulated tools.
Use eye protection device, and take preventive measures.
Wear rubber gloves and apron to guard against electrolyte overflow.
In battery transportation, the electrode of the battery should always be kept facing upward. Never put the battery
upside down or slanted.
BLVD
The system has battery low voltage disconnection (BLVD) function. BLVD means when the mains fail and
batteries supply power, the controller cuts the load off when the battery voltage drops down to below 43.2V to
prevent over-discharge. The BLVD voltage is settable. Refer to ACU+ User Manual for setting method.
The factory setting is enabling BLVD, which means that if power outage lasts for a long time or the power system
fails, there might be BLVD. Users should classify the loads and connect the priority loads to BLVD routes. For
vital loads, users can disable BLVD of these loads to insure reliability of the power supply.
The method of disabling BLVD is:
Set “BLVD Enable” item of the controller to “N”. Refer to ACU+ User Manual for setting method.
Notice
The advantage of enabling BLVD is protecting the batteries from over-discharge when the battery voltage is low. The
disadvantage of enabling BLVD is that when the battery voltage drops down to a certain value, all the loads (including
non-priority loads and priority loads) will be cut off due to battery disconnection.
The advantage of software disabling BLVD is prolonging the power supply of priority loads. The disadvantage is that
software disabling cannot prevent unwanted power failure due to misoperation or power system failure.
Others
I. Sharp object
Warning
When moving equipment by hand, protective gloves should be worn to avoid injury by sharp object.
II. Cable connection
Notice
Please verify the compliance of the cable and cable label with the actual installation prior to cable connection.
III. Binding the signal lines
Notice
The signal lines should be bound separately from heavy current and high voltage lines, with binding interval of at least
150mm.

Chapter 3 Installation Testing
This chapter introduces procedures of installation testing. The corresponding safety rules shall be adhered to in the
test.
3.1 Installation Check And Startup
Before the test, inform the chief manufacturer representative. Only trained electrical engineer can maintain and
operate this equipment. In operation, the installation personnel are not allowed to wear conductive objects such as
watches, bracelets, bangles and rings.
During operation, parts of this equipment carry hazardous voltage. Misoperation can result in severe or fatal injuries
and property damage. Before the test, check the equipment to ensure the proper earthing. Installation check must be
done before testing. Then the batteries can be charged for the first time.
Make sure that the AC input MCBs, battery MCBs and load MCBs are switched off. Make sure that all the devices are
properly installed.
Installation check
Check all the MCBs and cables. Are their models correct?
Check the bus bar connections, input and output cable connection, and connection between the power
system and the system grounding.
Check the if the number and connections of the batteris are correct. Check the polarity of the battery string
with a voltmeter.
Make sure all the cable connections are firm and reliable.
OK
Comments
Startup preparations
Make sure that all the MCB are switched off.
Measure the AC input voltage. Make sure the input voltage is within the allowable range.
Check that the communication and alarm cables are connected to the signal transfer board.
Check that the temperature sensor, if any, has been installed.
Check that the battery string circuit is not closed.
Connect the disconnected batteries to the battery string circuit
Switch off unconnected battery MCBs. Check that the battery signal cables are connected to battery
MCBs reliably, not loosened or suspended
Measure with a voltmeter across the connection points of each battery and make sure that the polarity is
right. For a lead-acid battery with 24 cells, the voltmeter should read 2.0-2.1V/cell or 48-51V/battery. If the
voltage of certain cell is lower than 2.0V, that cell must be replaced.
Check with an ohmmeter that there is no short circuit between the positive & negative distribution bus
bars, or between the positive & negative battery poles
(Note: Pull out all modules before the check and restore them after the check)
OK

corresponding relay are the same with those of the high temperature alarm setting.
2. If the analog alarm has two levels of alarm thresholds, and if these two alarm thresholds are set to the same value,
then the second level will be cancelled and the first level of the alarm will be displayed in LCD. For example: If the
alarm threshold of ‘high temperature 1’ is set to the same with the threshold of ‘high temperature 2’, and if this
threshold is set to 40 deg C, then when the temperature exceeds 40 deg C, the system will only issue ‘high
temperature 1 alarm’, and will not issue the ‘high temperature 2 alarm’.
In the alarm level setting submenu, you can also set the output relay no. for the corresponding alarm.

Temp 2: Displays whether a temperature probe on MB is installed and enabled (Battery or Ambient) or not (None)
in position No. 2, and if there is one, whether it is used for battery or ambient temperature measurements.
Coeff: Displays the temperature compensation slope or rate of change per °C above or below the normal operation
level selected in the second line. This value is expressed in millivolt per °C per string (mV/°C/str). For example, for a
rate of change of 72mV/°C/str in a 24-cell, 48 V nominal, battery string, the rate of change is 3 mV per cell.

Chapter 5 Alarm Handling
This chapter describes the handling of alarms, as well as the preventive maintenance of the system during system
daily operation.
The maintenance personnel must have adequate knowledge about the power system.
Note
1. The maintenance must be conducted under the guidance of related safety regulations.
2. Only the trained personnel with adequate knowledge about the power system can maintain the inner part of the subrack.
5.1 Handling Alarms
The controller alarms are classified in four types: critical alarm, major alarm, observation and no alarm.
Critical alarm, major alarm: these two types of alarms have strong impacts on the system performance. Whenever
these alarms are generated, users are supposed to handle them immediately. The alarm indicators will be on and
audible indication will be given.
Observation: when this type of alarm is raised, the system maintains normal output for a while. If the alarm occurs
during watch time, it should be handled immediately. If the alarm occurs during non- watch- time, handle it during
watch time. The alarm indicators will be on when observation alarm occurs.
No alarm: if alarms are set as ‘no alarm’ by the users, when these alarms occur, no visible or audible indication will be
generated and the system works normally.
The handling methods of normal alarms are given in Table 5-1.

If the failure does not last long, the battery will power the load. If the cause is unknown or the failure lasts
too long, a diesel generator is needed. Before using the generator power to supply the power system, it
is suggested to run the generator five minutes to minimize the impact on the power system
Check if the AC over-voltage value is too low. If yes, change the value.
A mild over-voltage does not affect the system operation. However, the rectifier will stop operation when
the mains voltage is more than 530V. If the mains voltage is above the AC over-voltage value, the mains
grid should be improved
Check if the AC Under- voltage point is too high. If yes, change the value.
When the mains voltage is lower than 304V, the output power of the rectifiers will be derated. And if
lower than 260V, the rectifiers will stop working. If the mains voltage is under the AC under-voltage value,
the mains grid should be improved
Check the SPD condition. If the SPD is damaged, replace it
Check the DC over-vlotage value through the controller. If the set value is inappropriate, correct it.
Otherwise, find out the rectifier that has caused the alarm:
1. Ensure that the batteries can operate normally.
2. Switch off the AC input of all rectifiers.
3. Power on the rectifiers one by one.
4. If the over-voltage protection is triggered when a certain rectifier is powered on, that rectifier is the
faulty one. Replace it
1. Check if the alarm is caused by mains failure, if yes, disconnect some loads to prolong the operation of
the whole system.
2. Check the DC under-voltage value set through the controller. If the set value is inappropriate, correct
it.
3. Check if any rectifier is inoperative, or has no output current. If yes, replace it.
4. Check if the total load current exceeds the total rectifier current during float charge. If yes, disconnect
some loads or add more rectifiers to make the total rectifier current bigger than 120% of the total load
current with one redundant rectifier
Check if the corresponding MCB is switched off. If the MCB is open, find out the fault and remove it.
Otherwise, the alarm circuit is faulty. Please contact Emerson

Check if the mains voltage is above 530V or under 260V. If the mains voltage is under the AC
under-voltage value or above the AC over-voltage value, the mains grid should be improved
Pull out the rectifier to check if the fan is obstructed. If yes, clean it and push the rectifier back. If the fan
is not obstructed or if the fault persists after cleaning, replace the fan
Check if the communication cable is connected properly between rectifier and controller. If yes, restart
the rectifier. If the alarm persists, replace the rectifier
1. Check if the battery compartment temperature is too high. If yes, cool down the battery compartment.
2. Check if there is battery internal fault. If yes, replace the faulty battery

Replacing rectifier fan
If the rectifier fan is faulty and does not work, it should be replaced. Take the R48-1800 rectifiers as an example, the
replacement procedures are as follows:
1. Use a cross screwdriver to remove the 3 screws from the fixing holes and pull out the front panel.
2. Unplug the power cable of the fan and remove the fan. Install a new fan.
3. Plug the fan power cable. Put the front panel back and fasten it with the 3 screws, as shown in Figure 5-2.

Replacing rectifier
Except replacing the fan, it is recommended not to repair any other part of the module. When faulty, the module
should be replaced, not repaired. See the following procedures to replace the rectifier.
1. Take a new rectifier and check it for any damage from transport.
2. Loosen the fixing screw of the handle of the R48-1800A rectifier with a Phillips screwdriver. Pull out the faulty
rectifier from the rack by grabbing its handle.
Be careful with the rectifier just pulled out from the system, as it could be very hot due to long-term operation. Do not
let it slip away and get damaged.
3. By holding the rectifier handle, push the new rectifier into the slot just vacated and make sure the connection is
good. After a brief delay, the rectifier run indicator will turn on and the fan will start running.
4. Check whether the new rectifier works normally. You should make sure that:
1) The controller recognizes the new rectifier.
2) The new rectifier shares current with other rectifiers.
3) When this new rectifier is pulled out, there is a corresponding alarm and the controller displays the alarm.
If the new rectifier passes all the above tests, the replacement is a success.
5. Push the handle back into the front panel to fix the rectifier with the positioning pin. Fix the fixing screw of the
handle of the R48-1800 rectifier with a Phillips screwdriver.

Rectifier
Over-voltage protection
The rectifier provides over-voltage hardware and software
protection. The hardware protection point is 59.5V ± 0.5V, and it
requires manual resetting to restore operation. The software
protection point is between 56V and 59V (0.5V above output
voltage, 59V by default), and can be set through the controller
There are two software protection modes, which can be selected
through the software at the host:
1. Lock out at the first over-voltage
Once the output voltage reaches protection point, the rectifier will
shut off and hold that state. It requires manual resetting to restore
the operation
2. Lock out at the second over-voltage
When the output voltage reaches the software protection point, the
rectifier will shutdown, and restart automatically after 5 seconds. If
the over-voltage happens again within a set time (default: 5min.
Configurable through controller), the rectifier will shut off and hold
that state. It requires manual resetting to restore the operation
Manual resetting: Resetting can be done manually through the
controller, or by removing the rectifier from system
