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).

9. Green power LEDs on faceplate will illuminate when AC power is present. When an output is in a trouble
condition (blown fuse or tripped PTC) the corresponding LED will not be illuminated (Fig. 1, pg. 3).
a. Blown fuse (R248220, R248300220, and R248600220) - set power switch on the back of the unit to the
OFF position (Fig. 1c, pg. 3). Remove front faceplate to access fuses.
Replace with fuses rated @ 3.5A/250VA (R248220 and R248300220).
Replace with fuses rated @ 5A/32VA (R248600220).
b. Tripped PTC (R248CB220, R248300CB220, and R248600220) - to reset PTC, set power switch on the
back of the unit to the OFF position. After approximately 30 secs. set power switch to the ON (RESET)
position (Fig. 1c, pg. 3).
10. Power switch with built-in circuit breaker:
OFF position - Switch not illuminated. Outputs not powered.
RESET (ON) position - Switch illuminated. Outputs powered.
Circuit breaker tripped - Switch not illuminated. Power LEDs on faceplate are not illuminated.
Outputs not powered. To reset circuit breaker set power switch to the ON (RESET) position (Fig. 1c, pg. 3).
Note: Do not exceed units electrical load ratings as indicated in reference chart (pg. 2).
Do not place mechanical load on unit. Data racks should always be properly ventilated.
Unit is designed optimally for normal data room office installations.
CAUTION: Equipment to be installed / serviced by authorized / trained personnel only.
Shut branch circuit power before installing / servicing equipment.
WARNING: To reduce the risk of fire or electric shock, do not expose the unit to rain or moisture.
This installation should be made by qualified service personnel and should conform to
the National Electrical Code and all local codes.
