Installing the Inverter/Charger
This guide for use by qualified personnel only.
Step 5: Connecting the Battery Temperature Sensor (BTS)
Installing a battery temperature sensor (BTS) extends the life of a
battery by preventing overcharging in warm temperatures and
undercharging in cold temperatures. With a BTS monitoring the
battery temperature, the voltage delivered to the battery is adjusted
according to the battery’s actual temperature.
The BTS has a self-adhesive backing and attaches to the side of the
battery. A 7.6 m cable is supplied with the BTS.
Mounting Options
You can mount the BTS in one of two ways:
• Mounting the sensor to the negative battery post allows the
internal battery temperature to be sensed and provides the most
accurate results.
• Attaching the sensor to the side of the battery using the self-
adhesive backing also provides good results in most situations.
