Important Notes
Always wipe the contacts clean before plugging and unplugging.
When disconnecting, unscrew the coupling nut and pull the connector straight out—do not twist left/right, and never pull directly on the cable.
Avoid sharp bending of the cable during use.
When installing bulkhead joints, ensure the joint remains perfectly aligned and does not tilt.
All connectors are prohibited from prolonged exposure to direct sunlight or high heat to prevent material degradation.
