Installation and Maintenance Tips

Installation: Strip conductors to the recommended length, insert into pressure screw terminals, and torque to spec for a gas-tight connection. Always ensure the mating plug is clean and undamaged before connecting. Grounding is critical—verify continuity post-install.

Maintenance: Periodically inspect gaskets for wear, clean contacts with approved solvents, and test for continuity. In salty environments, rinse with fresh water after exposure to extend life.

Following these steps maximizes safety and performance, preventing common issues like overheating or arcing.
