7.11.1 Connection to the Liebert XDP or Liebert XDC
The Liebert XDP and Liebert XDC have two CANbus ports each (P2 and P4) on the CAN Isolator in
the low voltage side of the electrical box (see Figures 129 and 130). This allows for two chains of the
network to be created to minimize the total network length.
