REFER TO THE FILED WIRING DIAGRAM AS A GUIDE IF YOU
DO NOT HAVE A SPECIFIC WIRING DIAGRAM FOR YOUR
SYSTEM. FOLLOW YOUR LOCAL ELECTRICAL CODES AND
REGUATIONS FOR MINIMUM WIRE SIZE AND ROUTING.
2.3.2 Connecting Incoming Power - Field Mount
To connect the incoming power, use the following procedure.
Note: All units shipped from the factory are configured for 115 VAC. If you
desired 230 VAC make sure the power selector switch is set to 230 VAC
(Section 2.5.1).
1. Loosen the screw latch mounted on the front chassis. Open the door (see
Figure 2-3).
2. Route incoming power wiring through a conduit hole at the bottom right of
the enclosure. Leave ample loose wiring (typically 8”) to facilitate
removing the terminal connectors.
3. Wire safety ground terminal located on the side of the chassis.
4. Wire HOT to Terminal L on Power Input Terminal.
5. Wire NEUTRAL to Terminal N on Power Input Terminal.
6. If additional I/O is required at the line voltages, these wires should be routed
through a conduit hole on the bottom right of the enclosure. Leave ample
loose wiring (typically 8”) to facilitate removing the terminal connectors.
