Safety Precautions
To reduce the chance of accident, please read the safety precautions very carefully before operation. The
"Caution, Note, Warning, Danger" in this book and on the product 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 receive strict training and master the correct operations and all the safety points before operation.
When operating Emerson products, the operation personnel must observe the safety rules in the industry, the
general safety points and special safety instructions specified in this book.
Electrical Safety
I. Hazardous voltage
Danger
Danger
Some components of the power supply system carry hazardous voltage in operation. Direct contact or indirect contact
through moist objects with these components will result in fatal injury.
Observe safety rules in the industry when installing the power supply 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 and rings.
When you spot the cabinet with water or moisture, turn off the power immediately. In moist environment,
precautions must be taken to keep moisture out of the power supply 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
In high voltage and AC operation, specialized tools must 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
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, 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 power supply system or the
non-grounding pole and the earth. The power supply system is a constant-voltage DC power device, short circuit will result
in equipment burning and endanger human safety.
Check 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.
Use insulated tools.
In live operation, keep the arm, wrist and hand tense, so that when the tool in operation slips, the movement of
the human body and tool is reduced to a minimum.
BLVD
The power supply system has battery low voltage disconnection (BLVD) function. BLVD means when battery
voltage drops down to 43.2V, the power supply system cuts the load off to prevent over-discharge.
BLVD is enabled before delivery, 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 to ensure reliability of the power supply.
The method of disabling BLVD is:
Set ‘BLVD disabled’ parameter through the monitoring module main menu Settings (password: 1) LVD
BLVD.
Warning
Notice
Note
The advantage of BLVD is protecting the batteries from over-discharge. The disadvantage of 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 disabling BLVD is prolonging the power supply of priority loads. The disadvantage is that disabling
cannot prevent unwanted power failure due to misoperation or power supply system failure.
Others
I. Safety
Warning
Notice
Note
When replacing power input fuses of monitoring module and power distribution units, use the same type fuses to meet the
safety requirement.
II. Sharp object
Warning
When moving equipment by hand, wear protective gloves to avoid injury by sharp object.
III. Power cable
Warning
Notice
Note
Please verify the cable labels before connection.
IV. Signal cables
Warning
Notice
Note
The signal cables should be routed at least 150mm away from power cables.
