Installing Optional Accessories
The XC Series ships with a battery temperature sensor (BTS) and drip protection
rubber boots for the DC cables.
Battery Temperature Sensor
Xantrex strongly recommends that you install a Battery Temperature Sensor (BTS)
to protect your battery and improve charging accuracy. It is best to use a separate
BTS with each individual battery bank, to provide optimal charging and protection
of each bank. If no BTS is connected, the charger defaults to the charging
conditions for 40 °C (104 °F). At this temperature the charging voltage is lower to
keep batteries from overcharging; charging will be slower and the batteries will be
slightly undercharged.
One BTS is provided with with your XC Series and additional battery temperature
sensors may be purchased separately.
To install a BTS:
1. Switch off all devices operating from the battery.
2. Connect the ring terminal on the sensor directly on to the negative battery stud,
or affix the double-sided adhesive backing (included) to the sensor back and
attach the sensor to the side of the battery to be monitored.
3. Route the sensor cable to the charger and plug it into the bank 1 (default if using
only one BTS), bank 2 or bank 3 connector on the rear panel.
