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 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 the OFF position.
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
