Specifications:
Installation Instructions:
1. The unit is factory set for 24VAC operation.
For 28VAC operation adjust unit prior to mounting and applying power as follows:
a. Open bottom of the unit by removing six (6) screws (Rack Mechanical Drawing & Dimensions, pg. 4).
b. 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).
c. After securing all wires for proper voltage place bottom panel back on the unit and fasten with the six
(6) screws.
2. Mount unit in the desired rack location (Space unit at least 3” from any video monitors).
3. Set power switch on the back of the unit to the OFF position (Fig. 1c, pg. 3).
4. Plug power cord into grounded 220VAC, 50/60 Hz receptacle (Fig. 1b, pg. 3).
5. Set power switch on the back of unit to the ON (RESET) position and measure output voltage before
connecting devices (Fig. 1c, pg. 3). This helps avoiding potential damage.
All terminals with common suffix (P) “1P, 2P...” are the same polarity.
6. Set power switch on the back of the unit to the OFF position (Fig. 1c, pg. 3).
7. 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.
8. Upon completion of the wiring, set power switch on the back of the unit to the ON (RESET) position
(Fig. 1c, pg. 3).
