AC Power (Mains) Connections, Continued
Step Action
3. Install 15-Ampere circuit breakers; disconnect switches or
receptacles in the incoming power supply lines or two
switched receptacles near the unit. This will ensure the
power supplies will be completely separated from each of
the power sources. Label the breakers or receptacle boxes
to make sure that the circuits are clearly identifiable.
Note: For one input power sources only a single breaker
box or switch receptacle is required.
4.
Remove the wiring access plates from ANG. Punch holes
as required for either conduit or cable gland connectors for
both power and I/O lines. Install connectors and replace the
plates. For Zone 1 units (Figure 1-4) use one of the pre
tapped holes
Important
If you are going to install a Fiber Optic Coupler Assembly
select the egress locations and punch required holes.
5. Route input power, in accordance with pertinent electrical
codes and regulations, to ANG. Use entry holes provided in
step (4).
6. Locate the AC Power Input connector. To make the AC
connections easier the Power Input Connector comes apart.
Simply loosen the two recessed captive screws, grasp the
top portion of the connector and pull it straight out from the
base connector.
Loosen the top wire retaining screws from the removed
connector. Strip the insulation ¼ -inch back from each of the
input power leads. Insert each lead in the correct location,
and tighten down the retaining screws.
