Installation and setup
Wall mounting: Remove all equipment before mounting. Use appropriate hardware for your wall type. Each mounting hole can accommodate M8, M10, 5/16", or 3/8" screws.
Grounding: Use an M6 screw to attach a grounding cable to the front or rear grounding point. Route the cable under the frame and connect it to your facility's earth connection.
Door reversal: The front door can be reversed to open from the left or right. Use the levers at the top and bottom of the door to release it from the hinges, flip it, and re-insert the levers into the hinge holes on the opposite side.
Adjusting mounting rails: Rails can be adjusted in 20 mm (3/4 inch) increments. Remove the screws and cage nuts at the top and bottom of the rails, move them to the desired depth, and re-secure them. Rails can also be flipped to face the threaded holes toward the front.
Cable access: Remove the two screws at the ends of the cable access covers to open the cable management ports.
Maintenance
Side panels can be removed by unlocking them, pulling the two tabs toward the center of the panel, and lifting the panel away from the cabinet. To reinstall, seat the panel in the bottom groove, pull the tabs, press the top into the frame, and lock.
