surge suppressor, mounting hardware, and waterproofi ng grommet.
Required Tools:
• Drill with 3/16" (4.8mm) bit. For older enclosures a 3/4" (19mm) bit is also
needed.
• Phillips screwdriver
• 3/8" (9.5mm) socket and driver
1. Drill two 3/16" (4.8mm) holes 1½" (38.1mm) apart (indicated locations are
recommended). Newer enclosures have center punch marks on the left and right
side of the enclosure.
2. Attach the surge protector to the inside of the enclosure wall with provided
hardware. For proper grounding, ensure the included star washers come in
contact with the enclosure wall.
3. On newer enclosures, knock out one of the 3/4" (19mm) knockouts located in
the upper rear of the enclosure. On older enclosures, drill a 3/4" (19mm) hole
in desired location. Press the grommet into the hole from the outside of the
enclosure.
