7.12 CANbus Termination
The last device in the chain must be terminated.
• The remote temperature and humidity sensors are terminated at the factory.
• The Liebert XD smart modules are not terminated at the factory. Improper termination will
cause communication errors.
7.12.1 Remote Temperature and Humidity Sensors Termination
The control board is terminated at the factory. If a remote sensor is the last device in the CANbus chain,
no changes are necessary. The termination jumper must be removed if a remote sensor is not the last
device in the CANbus chain. Refer to the Liebert XD module user manual for terminating procedures.
