EPO Mounting
The Emergency Power-off Switch (EPO) is designed to be wall-mounted. Mounting accessories, including
screws and anchors, for common material types (drywall, plywood, concrete) are included in the standard
kit.
The QUATRA RED EPO has two (2) secure mounting tabs, one on each top/bottom side.
Caution. Make sure the area behind any surface is free of electrical wires or other dangerous elements
before drilling.
1. To mount the EPO, first determine the approximate location on the wall for the unit.
2. Hold the unit up on the wall and, using a pencil or similar marker, mark the mounting tabs points.
3. Using a drill, drill the location for the wall anchors.
4. Hammer in the wall anchors.
5. Place the EPO in the right location and screw on the mount.
EPO Grounding
1. Connect one side of the grounding cable to the grounding terminal on the equipment with a ¼" – 20
Bolt.
2. Connect the other end to the main grounding bar installed inside the fire room. The recommended
cable gauge is AWG #10 or AWG #12 and color code green/yellow.
