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
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
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
Warning
In high voltage and AC operation, special tools must be used. No common or self-carried tools should be used.
III. 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.
IV. ESD
Notice
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
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.
Battery
Danger
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 monitoring module 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 4.7.2 Battery Selection, 5.3.6Settings,
or 6.7.3Battery Settings for setting method.
The factory setting is enabling BLVD, which means that if power outage lasts for a long time or the power supply
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 monitoring module to “N”. Refer to 4.7.3LVD Parameter Description, 5.5.2Battery
Management Parameters or 6.7.3Battery Settings for setting method.
Notice
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 nonpriority 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 supply system failure.
Others
I. Sharp object
Warning
Warning
When moving equipment by hand, protective gloves should be worn to avoid injury by sharp object.
II. Cable connection
Notice
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
Notice
The signal lines should be bound separately from heavy current and high voltage lines, with binding interval of at least
150mm.

During the normal BC/FC management, the monitoring module regards the rated capacity as the capacity that each
battery group can reach. When the battery discharges, the monitoring module will calculate the battery remaining
capacity according to the discharge current, discharge time and the preset “battery discharge curve”. When the
battery is being charged, the monitoring module will calculate the real-time battery capacity according to the detected
charge current, charge time and preset “battery charge efficiency”. If the calculated battery remaining capacity is
higher than the rated capacity, the monitoring module will automatically change the calculated battery remaining
capacity to the rated capacity.

4.5.4 Changing Audible/Visual Alarm And Alarm Call Back Plan
There are different audible/visual alarms and call back modes for alarms of different levels. For the products in China
market, the alarming mode for major alarms and critical alarms are the same.
Table 1.1 Different alarms and call back modes for different alarm levels
Alarm level Red indicator Yellow indicator Alarm horn Call back Remark
Critical ON / ON Y Callback No. can be set
Major ON / ON Y Callback No. can be set
Observation / ON OFF N
No alarm OFF OFF OFF N
Therefore, changing the alarm level of different alarms may change their audible/visual alarm mode and call back
plan too.
Pressing any key on the monitoring module can silence the alarm sound. The sound will disappear and alarm
indicator will be off when all alarms are cleared.
You can configure how long an alarm sound will last, or choose to make no alarm sound. For details, see 4.7.11
Alarms Settings.
4.5.5 Changing Alarm Types Of Dry Contacts
As one of the alarm type parameter, “Related Relay” refers to the serial No. of the dry contract corresponding to the
alarm type, whose value is either 1 ~ 8 or “None”. “None” means there is no corresponding dry contact. For details,
see Alarm Settings.

ID01234567
5. Press "◄" and "►" to select the needed action.
“Start”: The options include “FC”, “BC” and “Test”. If system is not configured with any battery, the control would be
invalid. If there is AC power off alarm, or the busbar voltage is too low, the BC and battery test control will not be
executed by the system. No battery test control can be conducted when the rectifier communication is interrupted.
Finally, after the battery test, the battery management mode will be changed from “Manual” to “Auto” automatically.
“Battery”: The options include “Reconnect” and “Disconnect”. If there is no battery, or there is a battery alarm, the
battery operations will be invalid.
“Load”: The options include “Reconnect” and “Disconnect”.
The following maintenance over the rectifier can be conducted only when the power system is in the FC state.
”RectTrim”: Range: 42V ~ 58V. It can be used to improve the current sharing among rectifiers. Note that the value of
this parameter cannot exceed the over-voltage alarm point, or the parameter will be invalid.
”RectLimit”: Range: 10% ~ 121%.
The maintenance operations over a single rectifier include: “DC ON/OFF”, “AC ON/OFF” and “Reset”. The operation
method is:
1) Use “▲” or ” ▼” to select the rectifier parameter, and “◄” or “►” to change the rectifier serial No. Then press
“ENT” to confirm. The bottom line of the page displays the rectifier ID.
2) Use “▲” or “▼” to move the cursor to the maintenance operation area, and “◄” or “►” to select the value.
If the rectifier voltage is too high, you can select “Reset” to restore the output voltage of that rectifier to normal.
6. There will be prompts as the confirmation of control commands. If the maintenance operation is valid, system will
prompt you press “ENT” to confirm and execute the operation, or “ESC” to abort the operation. Otherwise, system will
prompt you the operation is invalid, and press “ESC” to quit.
Press ENT to run
Other Key Quit
or
No Maintain!
ESC Quit.
Press “ESC” to return to the menu of higher level.
4.7 Setting System Parameters
Battery parameters are very important, for they are related to the life of battery. Before delivery, the battery
parameters have been initialized. Without any special needs, you only need to reset the battery group number and
battery capacity, and accept the defaults for other parameters.
