Battery Temperature Sensor Mounting

A 40 ft battery temperature sensor cable is shipped with your device. This three-wire cable carries a
voltage signal to the power supply from a sensor element which must be mounted close to the storage
battery. Voltage is proportional to the battery temperature and the diagnostic circuitry in the power
supply module. The 40 ft cable can be extended to a total length of 190 ft using 50 ft extensions
(Motorola Solutions part number 3084827Y04. See
Mount the sensing element of the temperature sensor so that it detects the actual battery temperature
(or the ambient temperature as close as possible to the batteries being charged). The two examples of
mounting are as follows:
Example 1
Use cable ties to attach the sensing cable to the positive (or negative) power cable. A minimum of two
cable ties should be used (spaced 6 inches apart), with one of the cable ties not more than 2 inches
from the sensing element. Mount the sensing element not more than 2 inches from the battery post
where the power cable connects. See
