Conext XW Pro Installation Guide
Note: For all BTS compatible Xanbus enabled devices in the system, at least one BTS
must be separately installed for each device type associated with a battery. If there is a
group of the same devices forming a multi-unit setup, only one BTS is required per
device type connected to the same battery (same DC association). See the installation
guide of each device for BTS installation instructions.
The Battery Temperature Sensor (BTS) regulates battery charging based on battery
temperature. The BTS extends battery life by minimizing overcharging in warm
temperatures and undercharging in cold temperatures.
The BTS connects to the Conext XW Pro via the BTS port, which is located at the
bottom of the Conext XW Pro chassis, next to the communication ports.
Note: Connect the BTS to the batteries only after the battery bank has been prepared
and is ready to connect to the inverter.
To install the Battery Temperature Sensor:
1. Route the BTS cable through your preferred conduit route and insert the BTS jack into
the BTS port.
2. Route the BTS cable to the battery enclosure, and then connect the BTS using one of
the following methods (as shown in Figure 26):
3. Connect the BTS ring terminal directly to a battery terminal (recommended), or:
4. Attach the BTS to any side of the battery you wish to monitor by using the adhesive
backing on the BTS.
Note: When using the adhesive backing, install the BTS on the side of the battery
below the electrolyte level.
Installation tip
Place the sensor between batteries and place the batteries in an insulated box to reduce
the influence of the ambient temperature outside the battery enclosure.
