Exception: Conductors of AC and DC circuits, rated
1000 volts nominal, or less, shall be permitted to occupy
the same equipment, cable, or conduit. All conductors
shall have an insulation rating equal to at least the
maximum circuit voltage applied to any conductor within
the equipment, cable, or conduit. See NEC 300.3(C)(1).
Connecting Smart A/C Module
The Smart A/C Module can control an air conditioner (24
VAC) directly. See Figure 3.1.

Auxiliary Contacts
If desired, there is one normally-closed Auxiliary Contact
on the transfer switch to operate customer accessories,
remote advisory lights, or remote annunciator devices. A
suitable power source must be connected to the common
terminal. If needed, an extra auxiliary contact can be
added.
NOTE: Auxiliary Contact is rated 10 amps at 125 or 250
volts AC.

Figure 3-1. Typical Smart A/C Connections
Control of Air Conditioner Load
1. Route the thermostat cable (from the furnace/
thermostat to the outdoor air conditioner unit) to the
transfer switch.
2. Connect the wire to the terminal strip terminals (A/
C 1) on the Smart A/C Module as shown in Figure
3.1. These are normally closed contacts which
open upon load shed conditions. Route thermostat
wire away from high voltage wires.
3. If required, connect additional air conditioners to
the terminal strip terminals (A/C 2-4).

NOTE: These instructions are for a typical air conditioner
installation. Control of certain heat pumps and 2-stage air
conditioners may require special connections or the use
of Smart Management Modules (SMM) to control the
loads.
