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
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.
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
In high voltage and AC operation, specialized tools must be used.
III. Thunderstorm
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.

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
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.
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.

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
When moving equipment by hand, wear protective gloves to avoid injury by sharp object.
III. Power cable
Please verify the cable labels before connection.
IV. Signal cables
The signal cables should be routed at least 150mm away from power cables.

This chapter introduces installation and cable connection. Before installation, please read through safety regulations,
and then follow the instructions provided in this chapter to carry out the installation and cable connection.
2.1 Safety Regulations
Certain components in this system carry hazardous voltage and current. Always follow the instructions below:
1. Only the adequately trained personnel with satisfactory knowledge of the power system can carry out the
installation. The most recent revision of these safety rules and local safety rules in force shall be adhered to during
the installation.
2. All external circuits that are below -48V and connected to the power system must comply with the requirements of
SELV as defined in IEC 60950.
3. Make sure that the power (mains and battery) to the system is cut off before any operations can be carried out
within the system cabinet.
4. The power cabinets shall be kept locked and placed in a locked room. The key keeper should be the one
responsible for the system.
5. The wiring of the power distribution cables should be arranged carefully so that the cables are kept away from the
maintenance personnel.
2.2 Preparation
Unpacking inspection
The equipment should be unpacked and inspected after it arrives at the installation site. The inspection shall be done
by representatives of both the user and Emerson Network Power Co., Ltd.
To inspect the equipment, you should open the packing case, take out the packing list and check against the packing
list that the equipment is correct and complete. Make sure that the equipment is delivered intact.
Cables
The cable should be selected in accordance with relevant industry standards.
1. Cable specifications of NetSure 211 C45-S1 power supply system
It is recommended to use the RVVZ cables as AC cables. The cable should reach at least +70°C temperature
durability. Select the AC cable Cross-Sectional Area (CSA) according to Table 2-1.
Table 2-1 AC cable CSA selection
1.5mm2 (AWG14) ~ 2.5mm2 (AWG12)
The CSA of DC cable depends on the current flowing through the cable, the allowable voltage drop and load peak
current. The recommended load peak current is 1/2 to 2/3 of MCB or fuse capacity.
Select the battery cable CSA according to Table 2-2. Select the load cable CSA according to Table 2-3.
