Mounting to the Negative Battery Terminal
To mount the sensor on the negative battery terminal:
See Figure 10.
1. Select the battery to be monitored. The BTS should be connected to the
battery bank that 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 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 BTS 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.
6. Mount the sensor directly on top of the ring terminal, as shown in Figure 10,
and firmly tighten the terminal nut.
7. Check to ensure that the sensor and all wires are held firmly and cannot be
moved.
8. Turn the battery switch on again (if you opened it in Step 2.)
9. Route the sensor cable to the inverter/charger and plug it into the Battery
Temp jack, as shown in Figure 11. Secure the cable along its length.

WARNING: Fire hazard
In this procedure, you must install the DC wire on the battery terminal, then install the
sensor on top of the DC wire. This sequence is required to provide the best connection to
the battery and to ensure correct performance of the sensor.
