Liebert iCOM Display Components and Functions

Notes on Wiring for a U2U Network—Refer to Figures 13 and 15

1.See unit electrical schematic.

2.Cable ‘A’ and ‘B’ are provided with each unit. One only is used as follows:

•Liebert IntelliSlot based communications - Cable ‘A’ is preconnected to P65 on I/O board and P65 on the Liebert IntelliSlot power supply

•Non-Liebert IntelliSlot-based communications—Cable ‘B’ is pre-connected to Terminals 77 & 78 but must be exchanged with Cable ‘A’ at P65 on the I/O board.

3.A Liebert IntelliSlot option bay is provided for a maximum of two optional Liebert IntelliSlot Web-LBDS or Liebert IntelliSlot 485-LBDS cards.

4.When a large display is used, both cables (P64A and P66) are required.

5.On units with the standard small display, Cable ‘C’ is provided for unit to unit (U2U) networking. Cable ‘C’ is pre-connected to P64A on the I/O board. The customer connection point is in the field- wiring area near the Liebert IntelliSlots.

6.On units with the optional large display, Cable ‘C,’ Cable ‘D,’ and a crossover coupler are provided for unit-to-unit (U2U) networking. To enable U2U networking, unplug the red cable from P64A near the I/O board and connect to one side of the crossover coupler. Connect Cable ‘C’ to P64A as shown. The customer connection point for Cable ‘C’ is located in the field wiring area, near the Liebert IntelliSlot bays. Connect Cable 'D' to the other side of the crossover coupler as shown. The customer connection point for Cable 'D' is also in the field wiring area, near the Liebert IntelliSlot bays. This connects the I/O board and the display to the private U2U network.

7.When the optional remote T/H sensors are supplied, the customer connection point is in the field wiring area, near the Liebert IntelliSlot bays. The cable supplied with the remote T/H sensors is marked unit end and sensor end. Match the six-pole plug on the unit end of the cable with the six- pole connector in the unit. Secure the fork terminal on the cable shield to the metal plate adjacent to the six-pole connector.
