Freedom SW 230V Installation Guide

Installing the Inverter/Charger

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 11, and firmly tighten the terminal nut.

7.

Check to ensure that the sensor and all wires are held firmly 
and cannot be moved.

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.
