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 or rings.

When you find water or moisture is on the cabinet, then turn off the power immediately. In moist environment,

precautions must be taken to keep moisture out of the cabinet.

‘Prohibit’ warning label must be attached to the switches and buttons that are not permitted to operate during

installation.

Danger Danger

High voltage operation may cause a fire and an 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.

Danger Danger

To avoid electric shock hazard of outdoor environment and outdoor equipment, the non-professionals are prohibited to

operate or maintain the power system.

III. Tools

Warning

In high voltage and AC operation, special tools must be used. No common or self-carried tools should be used.

IV. Thunderstorm

Danger 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.

V. ESD

Note

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, you must wear ESD wrist strap to prevent body static from

damaging the sensitive components. The other end of the ESD wrist strap must be well earthed.

VI. Short circuit

Danger 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 constant voltage DC power equipment, and short circuit will result in equipment

burning and endanger human safety.

Chapter 5 Maintenance

This chapter describes routine maintenance, alarm and fault handling, and replacing parts of the power system.

Note

1. The maintenance must be conducted under the guidance of the related safety regulations.

2. Only trained personnel with adequate knowledge about the power system shall maintain the inner part of the subrack power

system.

3. There is a dangerous voltage at AC side, and the grid must be disconnected when maintaining the AC side.

5.1 Routine Maintenance

Inspect the power system periodically and shoot the trouble in time. The routine maintenance items are given in Table

5-1.

5.2 Handling Alarms And Fault

5.2.1 Handling Controller Alarms

You can query the controller alarms through LCD screen of the controller.

Alarm type

The controller alarms are classified into three types: critical alarm, observation alarm and no alarm.

Critical alarm: These two types of alarms have strong impacts on the system performance. Whenever these alarms

are generated, you should handle them immediately. The alarm indicators (see Figure 5-1) will be on and audible

indication will be given.

Observation alarm: 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 (see Figure 5-1) will be on when the observation alarm occurs.

No alarm: Alarms set as ‘no alarm’ by the users, will generate no visible or audible indication and the system works

normally.

Chapter 5 Maintenance 15

Handling common alarms

The handling methods of common alarms are given in Table 5-3.

Table 5-3 Handling methods of common alarms

No. Alarm Handling method

1 AC Failure

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

2 Rect Fan Fails 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

3 Rect Not Respond Check if the communication cable is connected properly between rectifier and controller. If yes,

restart the rectifier. If the alarm persists, replace the rectifier

4 Over Temp Check the temperature around the temperature sensor is too high, if so, find the cause and

reduce the temperature

5 Load Fuse Alarm,

Batt Fuse Alarm

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

6 DC Volt High

Find out the rectifier that caused the over-voltage alarm. pull out all the rectifiers under the

circumstance that the battery can supply power normally. Then insert the rectifiers one by one.

When inserting a certain rectifier, the system triggers over-voltage again, that rectifier is

over-voltage, replace it

7 DC Volt Low

1. Check if any rectifier is inoperative, or has no output current. If yes, replace it.

2. 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

8 LVD2 Check if there is mains failure, and the battery voltage is lower than the value of ‘LVD2’.

9 Rect Fault The rectifier with the fault indicator (red) on is faulty.

Power off the rectifier, and then power it on after a while. If the alarm persists, replace the rectifier

10 AC Voltage High

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 305V. If the mains voltage is above the AC

over-voltage value, the mains grid should be improved

11 AC Voltage Low Check if the AC under- voltage value is too high. If yes, change the value.



No. Alarm Handling method

11 AC Voltage Low

When the mains voltage is lower than 176V, the output power of the rectifiers will be derated.

When the mains voltage is lower than 80V, the rectifiers will stop working. If the mains voltage is

under the AC under-voltage value, the mains grid should be improved

12 Rect Protect Check if the mains voltage is above 305V or under 80V. If the mains voltage is under the AC

under-voltage value or above the AC over-voltage value, the mains grid should be improved

5.2.2 Handling Rectifier Fault

When the rectifier has any other component failure except rectifier fan, the rectifier needs to be replaced. Therefore,

do not disassemble or replace any part of the rectifier other than the fan.

The symptoms of usual rectifier faults include: run indicator (green) off, protection indicator (yellow) on or blinking, fault

indicator (red) on or blinking.

The indicators of the rectifier are shown in Figure 5-2.

5.3 Replacing Parts

5.3.1 Replacing Rectifier

For rectifier, it is recommended not to repair any other parts. When faulty, the rectifier 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 rectifier handle. Pull out the faulty rectifier from the rack by grabbing its handle, as

shown in Figure 5-3.

Fixing screw of handle

Handle

Figure 5-3 Replacing rectifier

Note

The surface temperature of the rectifier just exit working is still very high, pay attention to grasp the rectifier to avoid falling

damage.

3. Hold the rectifier handle and push the new rectifier into the slot just vacated and make sure the connection is good.

After a brief delay, the run indicator of the rectifier will turn on and the fan will start running.

4. Check whether the new rectifier works normally.

You should make sure that:

1) The monitoring unit 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 monitoring unit 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, and tighten the fixing screw of the rectifier handle.

5.3.2 Replacing Controller

Controller fault: the run indicator (green) is off and the LCD screen does not display (external alarms may also be

triggered if a background system is connected).

Please check whether the system bus voltage is normal, and the controller connection terminal is reliable. If the above

two points are normal, then the controller is faulty, replace a new controller.

The replacing procedures are as follows:

1. Safety preparation

Attach one end of the effective grounding strap to the wrist and the other end to a suitable ground.

2. Loosen the locking screw on the controller to pull out the controller from the subrack power system until the

terminals J6, J7, J2 (when the temperature sensor is configured) are exposed. Unplug the connection terminal on J6,

J7 and J2, then pull out the controller from the subrack power system completely.

Parameter

category Parameter Description

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

Output delay Output voltage can rise slowly upon rectifier start up. The rise time is

configurable
