Installation Instructions:
1. Mount unit in the desired rack location (Space unit at least 3” from any video monitors).
Do not obstruct side air vents.
2. Set power disconnect circuit breaker to OFF position (Fig. 1c, pg. 3).
3 All units are factory set for 24VAC operation.
For 28VAC operation, adjust unit prior to mounting and applying power as follows:
Change the wire position so that the black wire [28V] is connected to the terminal marked [P] and
the yellow wire [24V] is connected to the terminal marked [S] (Fig. 1, pg. 3).
4. Plug power cord into a grounded 115VAC 50/60 Hz receptacle (Fig. 1b, pg. 3), ground should be connected
as indicated in Fig. 1d, pg. 3.
5. Set power disconnect circuit breaker to RESET (ON) position (Fig. 1c, pg. 3).
6. Measure output voltage before connecting devices. This helps avoiding potential damage.
All terminals with common suffix (P) “1P, 2P...” are the same polarity.
7. Set power disconnect circuit breaker to OFF position (Fig. 1c, pg. 3).
8. Connect devices to the removable terminal blocks marked [1P & 1N] through [8P & 8N] (Fig. 1a, pg. 3).
When wiring is completed on terminal blocks, they can be locked down by tightening screw flanges.
9. Upon completion of wiring, set power disconnect circuit breaker to RESET (ON) position (Fig. 1c, pg. 3).
