Safety recautions
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.
" rohibit" 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 A cables must be in compliance
with the local rules and regulations. Only those who are licensed to operate high voltage and A power can perform high
voltage operations.
II. Tools
Warning
Warning
In high voltage and A operation, special tools must be used. No common or self-carried tools should be used.
III. Thunderstorm
Danger
Danger
Never operate on high voltage, A , 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 P Bs, such as large-scale
I s. Before touching any plug-in board, P B or I 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 D distribution unit of the system or the non-grounding
pole and the earth. The power system is a constant voltage D 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
CBs, thus causing equipment damage and short circuit of CBs.
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 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 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.

After the system is powered on for the first time, you should set the system type according to the actual configuration.
The monitoring module will restart after the system type is changed. In that case, you should re-configure those
parameters whose default values are inconsistent with the actual situation. Only after that can the monitoring module
operate normally.
After configuring the system parameters, you can carry out various operations directly without resetting the parameter
values. As for those important parameters related to battery management, such as BLVD, you should be fully aware
of their influence upon the system before you change their values.
