5.4.1Connecting the Analog Sensors

The sensor inputs are factory-set to accept a 4 - 20 mA signal. The inputs can be changed by removing the appropriate jumpers on the control circuit board. See Table 13, Figure 5 and Figure 6.

The user supplied analog sensors MUST have their own power supply. To reduce the effects of inter- ference from any noise source, the sensor input wiring should be shielded twisted pair and the shield tied to earth ground at one end.

Analog input terminals for field connections are factory wired to the microprocessor board if specified when ordered. Eight terminals are located in the field wiring compartment of the unit. Wire sensors to the terminals as follows:

Table 13 Changing factory-set sensor inputs

Terminal	Signal
41	Input #1 (+)
42	Input #1 (-)
43	Input #2 (+)
44	Input #2 (-)
45	Input #3 (+)
46	Input #3 (-)
47	Input #4 (+)
48	Input #4 (-)

Consult your Liebert supplier for a field installation kit to add these connections after, if required.
