1.7.2 Dry Contactor Interface of Battery and Environmental Temperature Detection
The input dry contactor J2 and J3 detect the temperature of batteries and environment respectively, which can be used
in environment monitoring and battery temperature compensation.
J2 and J3 interfaces diagram are shown in fig.1-5 , the description of interface is in table.1-3 .

Position Name Purpose
J2.1 TEMP_BAT Battery temperature detection
J2.2 TEMP_COM Common terminal
J3.1 TEMP_ENV Environment temperature detection
J3.2 TEMP_COM Common terminal
Note: Specified temperature sensor is required for temperature detection (R25=5Ohm, B25/50=3275), please
confirm with the manufacturer, or contactor local maintenance engineers when placing an order.
1.7.3 Remote EPO Input Port
The UPS has an Emergency Power OFF (EPO) function. This function can be activated by pressing a button on the control
panel of the UPS or through a remote contactor provided by the user. The EPO pushbutton is protected by a hinged
plastic cover.
J4 is the input port for remote EPO. It requires shorting NC and +24v during normal operation, and the EPO is triggered
when opening NC and +24v, or shorting NO and +24v. The port diagram is shown in
fig.1-6 , and port description is shown
in table.1-4 .
