Clean dust and oil on the mating surface; check for bent/damaged pins/sockets and broken cables to ensure no defects before operation.
Align the alignment marks of male and female heads (with foolproof design for some models), push in smoothly until a "click" is heard for full contact.
Tighten the lock nut to fit the equipment/cable joint, avoid over-tightening (shell deformation) or loose locking (protection failure).
Loosen the lock nut completely first, then pinch the shell to pull out smoothly, strictly prohibit pulling the cable directly for unplugging.
Fix the cable with cable ties after installation to reduce plug and bending stress; reserve sufficient cable margin for moving parts.
Technical Note: Standardized plugging, unplugging and installation operations can effectively reduce the damage of M8 connector pins, shell and cables, and improve the overall service life; for the connectors used in moving parts such as mechanical arms, it is necessary to regularly check the locking state and cable fixation to avoid failure caused by vibration and loosening.
