Remove the explosion-proof motor wiring cover
Thread Content
Does the wiring cover of an explosion-proof motor need to be removed during installation? And how is the explosion-proof rating maintained after it is removed? Thank you!
If it’s not opened, how can the wires be connected? As long as the sealing surface and seal rings are not damaged, the explosion-proof rating will not be reduced.
When reinstalling it, a little 204 rust preventive oil can be applied to the flameproof surface
It’s opened for maintenance or installation! ! During the time it was disassembled, its explosion-proof rating must have decreased! ! Only after full restoration can the explosion-proof rating be achieved. If it is necessary to disassemble the device in order to meet the explosion-proof requirements, the entire pump unit must be moved to a safe area before it can be opened.
When making connections, ensure that the gland or flange is properly sealed and explosion-proof
I’ve never thought about this issue; usually I just take it apart and connect the wires directly
How can wiring be done without disassembling it? Once it is disassembled, as long as the sealing ring remains intact, there are generally no problems.
Power must be disconnected before disassembly. When opening the cover and connecting wires, pay attention to the sealing performance of the explosion-proof gland
If it is installed correctly, it will not affect the explosion-proof rating; so what’s the point of not removing it?
