Wiring Procedures and Diagrams
Preparation
1. Loosen the screws securing the controller access cover (see Figure 21) on each controller provided.
Cable Routing
All input and output connections to the circuit board are 24 Volt or less.
Although the cables do not have to be run in conduit, it is necessary that long runs of cable be supported or protected by
strapping them to the equipment piping. If conduit will be used to route the shielded cables, three factors must be consid-
ered:
1. DO NOT share the same conduit or raceway with 120 Volt or higher circuits.
2. Keep cables at least six (6) inches away from 120 Volt or higher electrical circuits.
3. GROUND the conduit (if metallic) to a known “earth ground” location.
A series of openings are located on the sides of the Smart Controller enclosure (see Figure 22). Strain relief fittings
are provided with the controller enclosure for interconnecting wiring. Install the plastic fittings as needed. Remove the
compression nut and rubber sleeve from each fitting. Prior to connection of the cable wires to the circuit board, slide the
compression nut and sleeve over the cable for the wiring connections. When wiring is completed, apply a small amount
of silicone to the rubber sleeve and reassemble. This will assure all wiring is secure and assist in making the tightening of
the fitting easier. Insert the plugs provided to block any holes not used for wiring or other accessories.
