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).
Table 2-2 Correlation of ports
2.4.6 Connecting Temperature Compensation Cable
If the user selects the temperature compensation cable, first loosen the captive
screw in the upper left of the controller, and slowly pull the controller out of the
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.
2.5 Installation Check
After the installation, you should carry out the inspection procedures given in
Table 2-3.
Table 2-3 Installation check list
Check that the power system is horizontally, vertically and steadily fixed
Check that all the bolts are tightened, especially those in electrical
connections. Check that the bolts have plain washers and spring
washers and are not reversed
Check that there are no unwanted materials inside the cabinet and clear
up the unwanted materials
Check that the power system is intact. If there are scratches, paint them
immediately with antirust paint to prevent corrosion
Check the correctness of all MCBs and cables specifications
Check the correctness of input and output cable connection, and
communication between the power system and the system grounding.
Make sure that all the cable connections are firm and reliable and the
cable binding is tidy and normative
Check the correctness of the battery strings polarities
Measure the resistance value between the positive terminal and
negative terminal and phase- to - phase resistance value in the AC loop.
Make sure that there is no short-circuit
Check the AC input and distribution. Check that the color of the AC
cables is normative, the cables are laid stably, and the safety labels are
complete
Check that the rectifiers are clipped tightly
Check that all the MCBs are switched off
3Testing
During testing, the corresponding safety regulations must be observed, and the
testing procedures should be followed strictly. The system has been tested before
delivery, the user does not need to carry on the field testing.
3.1Testing Distribution Unit And Rectifiers
Note
Before the test, inform the chief manufacturer representative. Only trained electrical
engineer can maintain and operate this equipment. In operation, the installation personnel
are not allowed to wear conductive objects such as watches, bracelets, bangles and rings.
During operation, parts of this equipment carry hazardous voltage. Misoperation
may result in severe or fatal injuries and property damage. Before the test, check
the equipment to ensure the proper grounding. Installation check must be done
before testing. Then the batteries can be charged for the first time.
Make sure that the AC output MCBs, rectifier MCBs and load MCBs are switched off.
Make sure that all the devices are properly installed.
Please check the power system according to below listed items.
Startup preparations
Make sure that all the MCBs are switched off.
Measure the AC input voltage. Make sure the input voltage
is within the allowable range.
Make sure that the communication and dry contact alarm
output cable are connected to the monitoring board
Make sure that the temperature sensor is installed correctly
Use a voltmeter to measure the battery string voltage and
make sure the battery polarities are correct
Check with an ohmmeter that there is no short circuit
between the positive & negative terminal of DC output,
between the positive & negative battery poles or AC input
terminals (Note: Pull out all modules before the check and
restore them after the check)
Startup
Switch on the system AC output MCB, the green LED on the
rectifier will be on after a certain delay
Switch on the load MCB. Use a multimeter to check the
voltage of both ends of load, if it shows 53.5V ± 0.5V, the
voltage is normal
Switch on the battery MCB
