Installation Instructions:
1. Unit is factory set at 12VDC. To adjust the output voltage remove the bottom cover to access DIP switch
on the power supply board (Fig. 1a, pg. 3).
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. 1e, pg. 3).
4. Plug power cord into a grounded 220VAC 50/60 Hz receptacle (Fig. 1d, pg. 3).
5. Set power switch to the ON (RESET) position and measure output voltage before connecting devices
(Fig. 1e, pg. 3). This helps avoiding potential damage.
6. Set power switch on the back of the unit to the OFF position (Fig. 1e, pg. 3).
7. Connect devices to the removable terminal blocks marked [1P & 1N] through [8P & 8N] (Fig. 1c, pg. 3).
When wiring is completed on terminal blocks, they can be locked down by tightening screw flanges.
All terminals with common suffix (P) “1P, 2P...” are the same polarity (positive).
All terminals with common suffix (N) “1N, 2N...” are the same polarity (negative).
8. Upon completion of the wiring, set power switch on back of unit to the ON (RESET) position (Fig. 1e, 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 (R1224DC68220) - Set power switch on the back of the unit to the OFF position
(Fig. 1e, pg. 3). Remove front faceplate to access fuses. Replace with fuses rated @ 3.5A/250VA
(Altronix model # Fuse1).
b. Tripped PTC (R1224DC68CB220) - To reset PTC, set power switch on the back of unit to the OFF
position. After approximately 30 secs. set power switch to the ON (RESET) position (Fig. 1e, 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. 1e, pg. 3).
