Instruction Manual

Installing the Battery Temperature Sensor
975-0400-01-01 Revision H 2–29
This manual is for use by qualified personnel only.
3. Connect the ring terminal on the BTS directly to the negative battery terminal
(recommended), or use the adhesive backing on the sensor back to attach
the sensor to any side of the battery to be monitored. See Figure 2-15.
If using the adhesive backing, install the BTS on the side of the battery below
the electrolyte level. It is best to place the sensor between batteries and
place the batteries in an insulated box to reduce the influence of the ambient
temperature outside the battery enclosure.
4. Pass the end of the BTS cable through a conduit hole on the solar charge
controller and insert the BTS plug into the BTS port. See Figure 2-16.
5. Replace the solar charge controller wiring compartment cover.

Important: The BTS cable must not pass through the same conduit used for PV
wiring and battery cables.
