9.2.3 Battery Temperature Sensor Kit
The battery temperature sensor is used to detect the battery temperature. With this function, we can adjust the float
charging voltage of the battery to make it inversely proportional to the ambient temperature of the battery, so as to prevent
the over-charge of the battery at high ambient temperature.
Preparation
1. Prepare the installation tools, including a cross head screwdriver.
2. Check that all installation materials are present and complete, including a battery temperature sensor.

1. Power down the UPS completely.
a. Turn off the load.
b. All UPS indication goes off, wait five minutes for the internal DC bus capacitors of the UPS to discharge
completely.
2. Connect one end of the network cable with shielded RJ45 port to the battery temperature sensor and plug the
other end into the J2 dry contact port on the UPS bypass. The temperature sensor can be connected in series
with a maximum of 20 sensors and a maximum distance of 50 m.
3. Route and pack the cables in order. Note that the cables should be routed separately from the power cables, to
avoid EMI.
