STEP 1 Mount the power supply

STEP 2 120 VAC wiring connection

Make sure 120VAC service is off at power supply PS1 (Breaker should be shut off).

Make sure 120VAC supply wire is rated at 90° C or higher.

Connect 120VAC supply wire to the AC input.

Connect ground wire to green pigtail attached to the enclosure chassis using the supplied wire nut.

Restore AC power to the power supply. Red LED should now be on.

STEP 3 Wiring the devices

Shut off breaker supplying AC power to the power supply.

Wire your exit device(s) per the diagram(s).

NOTE: NO VOLTAGE ON INPUTS...DRY CONTACT ONLY

Restore power to power supply and trigger the device(s) to make sure they are working correctly.

NOTE: The output voltage cannot be adjusted in an UL installation.

To adjust output voltage, locate adjustment dial shown and go to step 2.

Turn adjustment dial clockwise to increase output voltage. Turn adjustment dial counter-clockwise to decrease output voltage.

TROUBLESHOOTING
SYMPTOMS	POSSIBLE CAUSES	PROBLEMS
EL Exit device can't fully retract latch	Possibility 1 - Wire gauge from pwer supply to exit device is too thin	Check with your device manufacturer's wiring specifications.
	Possibility 2 - Distance from pwer supply to exit device is too far	Check with your device manufacturer's wiring specifications.
	Possibility 3 - Exit device out of adjustmernt	Re-adjust exit device according to manufacturer's mechanical recommendations.
Power supply not working and red LED not lit	Possibility 4 - AC fuse blown	Replace fuse with a 5mm x 20mm, 2.0 A 250VAC, slow blow fuse only
