Hey everyone!
I purchased 3 new servo motors and they have a power cable (which connects to the drive) which has the UVW and grounding wires, but also requires me two plug in L, N and a ground wire.

But i cannot find a way to open the connector to plug in wires. And i'm afraid to damage it trying, so i'm here asking for some guidance. How am i supposed to plug a wire here if it has no screw like regular terminals?

Also, should i feed direct power from the grid, or should i use filters like EMI? I have a few, can i use one for 3 motors if it has enough capacity? What else should i use to protect the circuit? The motors are AC 750W. I'm using pulse/dir as interface.


Thank you guys!

Those connectors have spring contacts. A special tool (looks like a thin awl) is inserted into the rectangular opening to release the wire.

You can buy the tool, or make one yourself with an old small screwdriver and a bench grinder.

CitizenofDreams is correct these are spring connectors. You can press wires into opening and use a small awl or paper clip in the tiny square hole I’ll release the wire. I also recommend you use EMI filter before the AC power source wires go to the servos
