Installation and usage precautions for power connectors are as follows:
Before installation, check if the voltage of the contactor coil matches the control power supply voltage. Then inspect the contactor's contacts for proper contact and for any signs of bridging. Clean the anti-rust oil from the iron core pole faces to prevent oil residue from causing a fault where the power cannot be released upon disconnection. Aviation Power
(2) During the installation of the contactor, its bottom surface should be perpendicular to the ground, with an inclination less than 5 degrees.
(3) When installing the GY series DC contactor, the holes should be positioned vertically to facilitate heat dissipation.
Do not allow screws, washers, and other components to fall inside the contactor during installation to prevent mechanical jamming and short-circuit failures. 36V Aviation Power Supply
(5) The contactor connector surface should be kept clean and, when necessary, lightly oiled.
When small metal beads form on the contact surface due to the arc effect, they should be promptly removed. However, for silver and silver alloy contact surfaces, the oxide film produced does not require filing as the contact resistance is very low; otherwise, it will shorten the lifespan of the contacts. 400HZ Frequency Converter Power Supply
