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.
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 30 meters, the CSA calculation
should be based on the current density of 2.5A/mm2. The suggested CSA value is
no less than 10mm2.
Select the DC load cable CSA according to the Table 2-1.

Note: The specs are applicable at ambient temperature of 25°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.
2.3 Installing Power System
The power system can be installed against the wall or installed into 19 inch rack.
Note
1. When installing the power system against the wall, make sure that the wall strength and
thickness meet the load-bearing and expansion bolt installation requirements.
2. The three brackets are fixed on both sides of the subrack power system before delivery.
1. If wall-mounting installation is used, firstly remove the three 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,
respectively fix the other two brackets after rotation to the middle of the subrack left
and right side wall. The position of the bracket is shown in Figure 2-2.
2. By referring to the dimension shown in Figure 2-1, mark the central points of the
installation holes on the floor. Use an electric drill (aiguille: Φ8) to dig holes (depth:
45mm) at the marked points. Clean the holes off dust. Put the four expansion pipes
(M6 ×65) into the holes and keep 20mm exposed.

4. After the installation, the cabinet should stand firmly no matter how it is shaken.
5. If rack mounting installation is used, firstly remove the three 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 any
one of the other two brackets after rotation to the front of the subrack right side wall
(the rest bracket is no need to be fixed). The position of the bracket is shown in
Figure 2-2, use the fixing screws to fasten the subrack power system to the rack
through bracket.
2.4 Cable Connection
All the cables entering or outgoing the power system must be put into the metal pipe
for protection. The metal pipe should be connected to the PE bar reliably. Plastic
coated metal hoses are recommended.
Danger
Danger
1. Switch off all MCBs before the electrical connection.
2. Only the qualified personnel can do the mains cable connection.
3. Before electrical connection, make sure all the AC MCBs of the power system are
switched off, the AC 230/400V 20A double pole C type MCB is recommended.
4. There is a dangerous voltage in the primary circuit, disconnect the power supply before
maintenance.

2.4.1 Connecting Earth Cable
Connect one end of the earth cable to the grounding terminal (see Figure 2-3), and
solder the other end to the grounding metal base outside the power system.
2.4.2 Connecting AC Input Cables
1. The routing method of the AC input cables is the same as that of the earth cables.
Connect the live line (L) and neutral line (N) of the AC input cables respectively to
the lower terminals of the power system AC input terminal L and AC input terminal N,
as shown in Figure 2-3.

2.4.3 Connecting DC Cables
The power system can be connected with three route of loads respectively
controlled by three MCBs, as shown in Figure 2-3. Connect the negative load cable
to the corresponding load '-' and then connect the positive load cable to the
corresponding load '+' (see Figure 2-3).
2.4.4 Connecting Battery Cable
The power system can be accessed in one group of batteries controlled by a battery
MCB, as shown in Figure 2-3. During connection, connect the negative battery
cable to the battery terminal '-' and then connect the positive battery cable to the
battery terminal '+' (see Figure 2-3).
2.4.5 Connecting Communication Cable
Connecting dry contact output port
The controller is configured with two pairs of alarm dry contact output (DO1 ~ DO2)
as standard configuration and four expanded outputs (DO3 ~ DO6) as optional. The
dry contact that generating corresponding alarm is normally closed, users can
connect according to actual needs. When wiring, take out the female of the 4-pin
phoenix terminal bound at the controller handle, connect the multi-core
communication cable with the pipe terminal to the corresponding female of the
phoenix terminal according to the dry contact silkprint on the controller, and then
insert the terminal into the controller front panel. The position of communication
terminal and port definition are shown in Figure 2-4 (Users need to prepare signal
cable themselves).
Figure 2-4 Illutration of controller front panel
Connecting RS232 port
The RS232 port is used for communication with the host. The correlation of the
RS232 and DB9 port on the host is shown in Table 2-2. When wiring, take out the
female of the 3-pin phoenix terminal bound at the controller handle, connect the
multi-core communication cable with the pipe terminal to the corresponding female
of the phoenix terminal according to the RS232 port silkprint on the controller, and
then insert the terminal into the controller front panel, as shown in Figure 2-4 (Users
need to prepare signal cable themselves).

power system until the 3pin temperature sensing interface J2 is exposed on the
monitoring board. Then table out the temperature compensation cable and insert
the cable into the interface, and then slowly push the controller into the power
system and fix the captive screw.

3.2Basic 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. The password of M225S
controller is 1.
