Mounting Options
You can mount the BTS in one of two ways:
• Mounting the sensor to the negative post of one of the house batteries allows
the internal battery temperature to be sensed and provides the most accurate
results.
• Attaching the sensor to the side of one of the house batteries using the self-
adhesive backing also provides good results in most situations.
Mounting to the Negative Battery Terminal
To mount the sensor on the negative battery terminal:
See Figure 14.
1. Select the battery to be monitored. The battery temperature sensor must be
connected to the house battery bank, which is directly connected to the
inverter/charger.
2. Switch off all devices operating from the battery, or open the battery switch (if
present) to disconnect the battery.
3. Wait 10 minutes for any explosive battery gases to dissipate.
4. Remove the nut that connects the existing wiring ring terminals to the battery
negative terminal stud.
5. Move or reorient the existing wiring ring terminals on the battery negative
terminal stud, so there is a flat surface on which to seat the battery
temperature sensor mounting plate.
You may need to bend the ring terminal crimp and/or wires slightly downward
to allow the sensor to seat flush to the top surface of the upper ring terminal.
WARNING: Energy and explosion hazard
