Battery Temperature Sensor Installation
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+ via the BTS port, which is located at the
bottom of the Conext XW+ chassis, next to the communication ports.
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 3-5 on page 3–10):
a) Connect the BTS ring terminal directly to a battery terminal
(recommended), or:
b) Attach the BTS to any side of the battery you wish to monitor by using the
adhesive backing on the BTS.
WARNING
BATTERY TEMPERATURE
The Battery Temperature Sensor provides necessary information for
performance and safety.
Always install and connect the Battery Temperature Sensor (BTS). See the
note directly below.
Failure to follow these instructions can result in death or serious injury.
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.
Note: Connect the BTS to the batteries only after the battery bank has been
prepared and is ready to connect to the inverter.
Note: When using the adhesive backing, install the BTS on the side of the battery
below the electrolyte level.
