To install the BTS:
1. Attach the ring terminal end of the Battery Temperature Sensor to the negative battery terminal;
see Figure 2-5 for proper connection to the battery terminal.
2. Route the sensor’s cable to the inverter following existing wire runs.
3. Connect the RJ11 connector end of the BTS cable to the yellow-labeled BTS Port on the
inverter (see Figure 1-1, Item 6).
2.4.6 Battery Temperature Sensor Installation and Wiring
The Battery Temperature Sensor (see Figure 2-7) provides the inverter with precise battery
temperature information to automatically adjust the ABSORB and FLOAT charge voltage set points.
This allows the batteries to be correctly charged under extreme temperature changes.
If the temperature sensor is NOT installed and the batteries are subjected to large temperature
changes, battery life may be shortened.
The BTS provided may be extended to a maximum length of 40 feet (12 m) using a RJ11 connector
(female to female) and a standard phone cable with RJ11 connectors. However, your inverter to
battery cable length shouldn’t exceed the recommended distance shown in Table 2-2.
