3 Installation Instructions
1. Unpack product. Do not discard packing materials until installation and checkout are successfully completed. Unit is
heavy, handle with care.
2. Mount unit in 19” rack only. Do not obstruct side air vents.
3. Verify that power switch on back of unit is in the OFF position (See Figure 2 - Rear View of Power Supply).
4. Plug power cord into grounded 117V, 60Hz (230V, 50/60Hz for HPR12DC616CE & HPR12DC616CBCE)
receptacle.
5. Set power switch on back of unit to ON (RESET) position and verify output voltage. Set power switch on back of
unit to OFF.
6. Connect CCTV cameras (or other external loads) to appropriate terminals. Connect circuit #1 to terminals marked
“1P” and “N”. Connect circuit #2 to terminals marked “2P” and “N”. Continue to connect the remaining circuits
carefully observing polarity. Terminals marked with “P” are positive.
7. Upon completion of wiring, set the power switch on back of the unit to the ON (RESER) position. The red power
indicator on the power switch should illuminate.
8. All 16 green LEDs on faceplate should illuminate. If an output has a blown fuse or tripped PTC the corresponding
LED will not illuminate.
9. Upon completion of wiring, secure terminal blocks by tightening screws on flanges..
4 Troubleshooting
1. If the red power indicator on the power switch is not illumated:
– Verify that power is present at receptacle.
– Verify that the unit is plugged into the power receptacle.
– Verify that the power switch is in the ON (RESET) position.
– Try resetting the circuit breaker in the power switch by setting to OFF position then back to ON (RESET) position.
2. If the green LEDs on the faceplate are not illuminated for outputs 1 to 8 and/or 9 to 16 while power switch is
illuminated:
– Set power switch on back of unit to the OFF position.
– Unplug power cord from receptacle.
– Remove field wiring to affected circuit(s) and check for shorts and overloads.
– Place field wiring after resolving any shorts and/or overload conditions.
– Allow the power supply to cool for five minutes.
– Plug power cord into receptacle.
– Set power switch on back of unit to the ON (RESET) position.
If the green LEDs do not illuminate after the power switch is set to ON:

WARNING:TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE
THIS APPLIANCE TO RAIN OR MOISTURE.
For continuous protection against hazard, replace fuses only with exact type and rating. All 117V/230V wiring
should be routed so that it cannot touch 12V wiring; minimum spacing 3/8” (0.953cm). This installation should be
made by a qualified service person and should confirm to all local codes. Install in accordance with the National
Electrical Code.
