1. Route thermostat cable (from furnace/thermostat to
outdoor air conditioner unit) to transfer switch.
2. Con
nect wire to the terminal strip terminals (A/C 1)
on SACM as shown in Figure 2-4. These are nor-
mally closed contacts which open upon load shed
con
ditions. Route thermostat wire away from high
voltage wires.
3. If
required, connect additional air conditioners to
the terminal strip terminals (A/C 2-4).
