Precautions For Use

1. To prevent looseness, please use gasket when installing contactor. M4 screw should be used at the installation of contactor, and the locking torque of screw should be controlled within 3N·m~4N·m; the allowable pulling force of lead out pin of contactor is (1) load outlet: ≤ 49n; (2) coil lead out pin: ≤ 49n. In case of exceeding the range, it may cause damage.
2. Please avoid sticking grease and other foreign matters on the lead-out piece, and use the connecting wire with the specification of more than 4mm², otherwise it may cause abnormal heating of the lead-in end.
