2.1 Safety Regulations
1. Only the adequately trained personnel with satisfactory knowledge of the power system
can carry out the installation and maintenance.
2. Prevent fire disaster and personnel injury.
3. Provide AC power supply that meets the requirement to equipment.
4. Make sure the equipment is well grounding.
5. Keep the equipment clean and dry.
6. Avoid of touching the bare parts of the circuit.
7. In case of suspicious failure, only can carry out 'Off' operation, shall not carry out 'On'
operation.
8. It is strictly forbidden to stand or place objects on the equipment body and accessories.
2.2 Preparation
Unpacking inspection
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.
Note
The rectifiers were installed in the subrack power system before delivery. If there are
rectifiers configured in the order, the rectifiers will be installed in the subrack power
system before delivery; if there is no rectifier configured in the order, then the subrack
power system will not be installed with rectifier at factory. Customers need to install the
rectifiers by themselves.
Preparing cables
The AC cable CSA should take into account the requirements like temperature rise, voltage
drop, mechanical strength and the cable design should meet relevant industry standards.
With cable length shorter than 30m, the CSA calculation should be based on the current
density of 2.5A/mm2. The suggested CSA value is not more than 10mm2.
Select the DC load cable CSA according to the Table 2-1.

Note: The specs are applicable at ambient temperature of 40°C. If the temperature is
higher than this, the CSA of the cable should be increased. The maximal cable CSA should
not larger than 10mm2
The CSA of DC cable depends on the current flowing through the cable, the allowable
voltage drop and the load peak capacity. The recommended load peak capacity is 1/2 to
2/3 of the MCB/fuse capacity.
The CSA of grounding cable should not less than 2.5mm2, and yellow-green double color
cable is recommended.
Determining subrack configuration
NetSure 2100 A31-S2/S3 subrack can be accommodated with 1 ~ 3 rectifies, the actual
configured rectifies are based on the order requirement. If the rectifier number is one, you
need to select two dummy plate. If the rectifier number is two, you need to select one
dummy plate. If the rectifier number is three, there is no need to select a dummy plate.
The appearance of the rectifier is shown in Figure 2-1, the layout of the subrack panel is
shown in Figure 2-2.

2.3 Installing Power System
The power system can be installed in 19 inch rack.
If rack mounting installation is used, firstly remove the two brackets, turn the bracket with
the grounding screw to make the grounding screw facing forward, and then fasten the
bracket to the front of the subrack left side wall, meanwhile, fix the other bracket after
rotation to the front of the subrack right side wall. The position of the bracket is shown in
Figure 2-3. Use the fixing screws to fasten the subrack power system to the rack through
brackets. Strictly follow the direction shown in Figure 2-4 when installing the subrack
power system. When carrying or installing the power system, it is prohibited to bottom up
or turn over the power system.

3.2 Basic Settings
The parameters of the power system are set at the factory, and the factory default setting
can meet the normal use of the power system. Users can modify the parameters (like AC
over/under-voltage point, DC over/under-voltage point and so on) of the power system
through background software. Users can also reset the commonly used parameters based
on actual needs through LCD screen of the controller. When setting the system
parameters, the user must enter the correct password before setting the parameters for
the controller. For NetSure 2100 A31-S2 configuration, the password of M225S controller
is 1.

For NetSure 2100 A31-S3 configuration, the password of M831A controller is 640275.
Users can log into the M831A controller webpage and set relevant parameters. When the
controller is powered on, you can find the IP address, subnet mask, default gateway in
‘Settings’-‘Communication parameters’ through the LCD screen, and note down them.
Then set the IP address of the local computer to the same LAN segment. For example, if
the controller IP address is 192.168.100.100, the IP address of the local computer can be
set to 192.168.100.101. Both the subnet mask and the default gateway are kept the same
as that of the controller. After that, log into the controller webpage by inputting the
controller IP address through a web browser. Login user name: admin; password: 640275.
After logging in, you can set the relevant parameters in the parameter setting page.
