Connecting the AccessWay to DC Power Supply (continued)

Step		Action
6.	Optionally, connect a remote alarm monitoring device to the
	AccessWay, to alert you to a fault in the DC output voltage.
	a)	Determine whether you want the alarm relay contacts
		open or closed when AccessWay output voltages are
		within normal operating range. The default setting is
		Normal Open.
	b)	Optionally, reverse this setting: at the front of the
		AccessWay, loosen a power module’s captive screws
		and pull the power module out of the AccessWay. Set
		the jumper to the Normal Closed position
		(Figure 1-12). Replace the power module in the
		AccessWay. Tighten the captive screws that secure it.
	c)	Connect two lengths of wire from the alarm monitor
		device terminals to the ALARM 1 terminals on the
		back of the AccessWay.
7.	If you disconnected the power terminal block from the rear of
	the AccessWay unit, replace it.
8.	Attach the cable clamp (Figure 1-13; provided with the
	AccessWay) to the wire bundle at the rear of the AccessWay.
	Leave a service loop of at least 8 cm between the clamp and the
	terminal block, and secure the clamp to the screw at the left of
	the terminal block.
	Ensure that any strain is relieved from the cable terminals, and
	that the power terminal block is easily accessible should you
	need to remove it quickly in an emergency.
9.	Apply DC power to the AccessWay.
	Verify that the LEDs near the bottom of the power module(s) are
	lit. The LEDs indicate the presence of input voltage and the
	status of output voltage.
