Installing the Optional Battery Temperature Sensor

(BTS)

Xantrex strongly recommends that you install the optional
Battery Temperature Sensor (BTS) to protect your battery
and improve charging accuracy. If no BTS is connected, the
charger can be set to one of three charging temperature
settings (Cold, Warm, or Hot). See “Installing Optional
Accessories” on page 2–25 for directions on how to use the
charger without a BTS. Regardless of its previous setting, if
the BTS connection is lost, the charger will default to Warm
in the next charging cycle.
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 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 to the
BTS port on the rear panel.
Note: If there are multiple batteries, attach the BTS to the
battery that is located in the warmest ambient temperature.
Important:
To minimize noise interference, the remote and
BTS cables should be routed away from the AC mains line and
DC battery cables.
Also, if the BTS is unplugged after a battery over temperature
fault, the charger will stop charging. Use the onboard display to
set the appropriate temperature setting to restart charging.
