1. See unit electrical schematic, installation and user manuals.
2. Cable “A” provided with each unit. Liebert IntelliSlot-based
communications - Cable “A” is preconnected to P65
on the microprocessor and input/output board and P65 on the
Liebert IntelliSlot power supply non-Liebert IntelliSlot-based
communications.
3. Install applicable Liebert IntelliSlot cards.
4. Both cables (P64 and P66) are required.
5. It is not necessary to connect the ground coupling on the end of the
cable connected to Sensor “A” or Sensor “B.”
6. A crossover coupler is provided for unit-to-unit (U2U) networking. Unplug
the red cable from P64 on the microprocessor and input/output board
and connect it to one side of the crossover coupler. The first customer
connection point is to P64 on the microprocessor and input/output board.
The second customer connection point is to the other side of the crossover
coupler. This connects the microprocessor and input/output board and
display to the private U2U network.
7. The remote sensors are interchangeable as to which connects to the Liebert
XD cooling module and which connects to P2 on CAN Iso.
8. Field-install cables with factory-installed ferrite beads (when provided,
typically two places). Each cable must make three passes through the
ferrite bead. Locate the ferrite bead on top of the electric box. See
the instruction sheet provided with the cable assembly.
9. Factory-installed ferrite bead (when provided). The cable passes through
the ferrite bead three times.
