If Using an AC Power Source
If using an AC power source, you must either cut off the plug and terminate the wires as you would a DC power
source or add a receptacle (not provided). If adding a receptacle, the vent and power gland can be swapped to
better accommodate a receptacle. If relocating the power cable entry port to a different location, be sure to move
the power cord wire gland insert (single hole) to the new entry port to ensure proper fit and maintain IP rating.
If using molded power cords, the IEC C1x type equipment connector will not pass through the wire glands
provided with the enclosure. The connector can be cut from the cord per the below instructions; push-on terminal
blocks are provided to reconnect the wires from the cord. There are typically three insulated wires:
•
green for earth (chassis) ground connection
•
white for neutral in 110VAC systems (or second leg in 220VAC systems)
•
non-white (black/blue/red) for the line (hot) in 110VAC (or first leg in 220VAC systems)
Cutting and Reconnecting AC Power Cord within Enclosure
1. Determine the length of stub connection needed to reach from the IEC C1x connector attached to the
equipment to the green, white and blue terminal blocks. Make sure to allow enough extra length to provide a
drip loop in the event that any moisture that potentially entered the enclosure while servicing the equipment
during inclement weather with the enclosure door open will not allow for water droplets to run down the power
cord wires and into the terminal blocks.
2. Cut the power cord to the desired length.
3. Pass the cut end of the AC mains wire from the outside of the enclosure through the strain relief/wire gland to
the inside of the enclosure.
4. Strip the outer sheath of both ends of the power cord to expose enough individual wire length for connecting
to the terminal blocks and allowing extra length for drip loops.
5. Strip the insulation on each wire back approximately 0.25" (6mm). After stripping the insulation, twist the
stranded wire ends to facilitate insertion of the wire into the terminal block.
6. Attach the green wires on both cut ends of the power cord to the green earth (chassis) ground terminal block:
push and hold the orange wire release button while inserting wire, then release to secure connection.
7. Attach the white wires on both cut ends of the power cord to the white terminal block.
8. Attach the non-white wires on both cut ends of the power cord to the blue terminal block.
Connecting DC Power within the Enclosure
1. Strip the insulation on each wire back approximately 0.25" (6mm).
2. Twist the stranded wire ends to facilitate insertion of the wire into the terminal block.
3. Insert ground (green) wire into green terminal block. Push and hold the orange wire release button while
inserting wire, then release to secure connection.
4. Insert DC positive (red) wire into red terminal block.
5. Insert DC negative (black) wire into black terminal block.
After Installing Cabling
Ensure all nuts are properly tightened and any unused openings are filled with hole plugs provided.
Power Wire Gland (x1): Using Torque Wrench, tighten nut to 75-80 in. lbs.
Data Wire Glands (x10): Using Torque Wrench, tighten nuts to 75-80 in. lbs
Improperly tightened nuts or unfilled wire inserts can affect NEMA/IP rating and void cabinet warranty.
