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).
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 2-6. 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).
2.4.4 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 take 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.

Table 2-7 Installation check list
1
Check that the rack is installed horizontally, vertically and steadily
2
Check that all the bolts and screws are tightened, especially those in electrical connections. Check that
plain washers and spring washers are present and not reversed
3
Check that there are no unwanted materials inside the rack and clear up the unwanted materials
4
Check that the rack paint is intact. If there are scratches, paint them immediately with antirust paint to
prevent corrosion
5
Clean up the rack
1
Check that all the MCBs and cable specifications are correct
2
Check that the bus and input/output cables are connected correctly, and that the system is grounded
correctly
3
Measure the resistance value between the positive terminal and negative terminal in the DC loop and
phase - to - phase resistance value in the AC loop. Make sure there is no shortcircuit
4
Check that the number and connection of the battery cell, and polarities of the battery strings are correct
5
Check that the battery cell number and connection
6
Check that the rectifiers are fastened down
7
Check that all MCBs are switched off
8
Check that the cables are tidy, and the cable binding is normative
9
Check the AC input and distribution. Check that the color of the AC cables is normative, the cables are laid
fast, and the safety labels are complete. See Appendix 4 Wiring Diagram for AC wiring and cable
connection
