Installing Gun ESD Protection
To protect the Gun and Gun Module from electrical shock you will need to install the Gun ESD PCB into
your cabinet. Follow the instructions below.
1. Make sure the cabinet is powered down and the AC unplugged from the wall outlet.
2. Locate the 5-pin Molex connector that connects the gun harness to the gun module.
3. Unplug the Molex connectors. Remove the male joiner pins as shown by the arrow in Part 2 and 3 of
the picture above
4. Install the ESD PCB next to the gun harness. Use wood screws to attach the PCB to the cabinet. The
green ground wire on the PCB should point down. See Part 4 of the picture above. The gun harness
should be able to reach the ESD PCB.
5. Plug the gun harness connector into the top of the ESD PCB. See Part 5 of the picture above. Plug
the gun module connector into the bottom of the ESD PCB.
6. Connect the grounding wire from the ESD PCB to the ground stud on the AC Power plate at the rear
of the cabinet. See part 6 of the picture above. This is a critical part of the ESD protection.
