Installation - Wiring Prerequisites
For the RS485 Modbus communications cable, Alpha XTRA Guard I cable (Alpha P/N 5121C) is required.
At the recorder end, the communications cable shield must be unconnected and must not extend into the
recorder enclosure. The shield of the communications cable must be connected to earth ground at the
farthest end of the cable. See the option wiring procedure for the RS485 Communications Card.
Inside of the enclosure, the user must install ferrite suppression filters and capacitors on all wires connected
to the recorder. ©Fair-Rite Products Corp. part number 0443164151, or equivalent, shall be installed as
shown in Figure 2-11 to Figure 2-22, one filter for each circuit group.
Cable with an outer jacket diameter larger than 6.7 mm (0.264 in.) may require the outer jacket to be
removed to fit the required one turn in the filter, or the selection of a different cable.
