3.27.3 Remote Sensor Placement Within the CANbus
Two remote sensors are shipped with the Liebert XDP. One shielded CANbus cable is provided with
each sensor. Sensor A is to be connected to the directly the Liebert XDP. Sensor B is to be connected to
the CANbus within the smart module chain. This can be at the end of the chain as shown in
Figure 45. For proper placement within the room, see 3.26 - Temperature/Humidity Sensor
Locations.

Sensor B can be placed in the middle of the daisy chain as shown in Figure 46; however, the
additional cable length must be subtracted from the allowable length.

The modules can also be split into two chains as shown in Figure 47.
