Terminal Definition Connection description
J402 ~ J404 Eight dry contact outputs Connected to signal cables
J433 Four wet contact inputs Connected to signal cables
J417 Battery temperature sensor terminal Connected to battery temperature sensor
J418 Ambient temperature sensor terminal Connected to ambient temperature sensor
J420 RS232 port Connected to a modem or an upstream host
J426 LLVD normally-closed contact
The port has been connected before delivery.
Switching on this port gets the LLVD contactor controlled by the
controller. For control condition, refer to 4.7.2 Battery Settings
J427 BLVD normally-closed contact
The port has been connected before delivery.
Switching on this port gets the BLVD contactor controlled by the
controller. For control condition, refer to 4.7.2 Battery Settings
J430 Providing 12V power to modem Connected to the power cable of the modem
Connecting temperature sensor cable
The temperature sensor is an optional accessory. The operating voltage of its probe is 5V, the measurement range is
-5°C ~ +100°C, the measurement precision is ± 2°C.
The installation procedures are described as follows:
1. Connect the three-core plug of the temperature sensor cable to the J417 or J418 terminal of the controller.
2. Put the temperature probe in the battery room where best represents the ambient temperature of the battery. Do
not connect it to other heat-generating equipment. When the battery is outside the cabinet, the temperature probe
cannot be placed in the cabinet.
Connecting dry contacts
The controller provides three pairs of dry contacts, which are J402 ~ J404 dry contacts shown in Figure 2-14.
The connection method is as follows:
Peel one end of the signal cable and insert it into the J402 ~ J404 terminals. Fasten the connection by tightening the
screw on the terminal.
The functions of J402 ~ J404 dry contacts are given in Table 2-5.
