Before wiring an alarm connector, familiarize yourself with the negative
and positive polarities of its two pins by examining the legends on the top
panel. Refer to Figure 34.

The following procedure shows the ALM OUT connector. The procedure is
the same for the ALM IN connector. To wire an alarm connector, perform
the following procedure:
1. Strip 6.5mm (0.25 in.) of insulation from the ends of the wires with a
wire insulator stripper. Refer to Figure 35.
Figure 35. Stripping an Alarm Wire
Warning
Do not strip more than the recommended amount of wire. Stripping
more than the recommended amount can create a safety hazard by
leaving exposed wire on the terminal block after installation.  E10
2. Tightly wrap the wire strands with your finger tips. Refer to Figure 36
on page 89.
This step is to prevent loose strands from touching other wires and
causing an electrical short.
