2016-09-13

1 there are occasions around the surge current machine.

1) contactor, relay, electromagnetic valve and other electromagnetic devices, to set the surge suppressor in its coil.

2) near the welding machine, try to stay away from the power supply.

2 signal lines are not used when the specified shielded twisted pair, please replace the use of.

3 use the correct grounding method.

1) confirm the ground resistance, less than 10 ohms.

2) from the frequency converter to be close to the ground (as short as possible).

3) the ground wire size should be enough to be consistent with the main circuit.

(4) the ground wire must be separated from other power lines and control signal lines (not parallel wiring, grounding wire is the source of interference)
