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 DNH unit. This will ensure
	DNH 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 wiring access plates from DNH. Punch holes as
	required for either conduit or cable gland connectors for
	both power and I/O lines. Install connectors and replace the
	plates.
5.	Route input power, in accordance with pertinent electrical
	codes and regulations, to DNH. 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.
