a. The power supply unit for plasma, CNC system and the enclosure of
machine must share a ground wire that is 2mm thick at least in diameter and
well connected to the ground.
b. Shielded cables must be used for the system input/output and the
exposed part at the cable end must not be longer than 30mm.
c. The unused input end must be connected to 24V ground wire.
d. A 0.01uF capacitor should be used between the 24V ground wire and
enclosure(shielded cable).
e. Use an isolation transformer(380V-220V) and as interference suppressor if
it is possible.
f. Separate the operational power supply for high-power welding
machine/cutting machine from that for CNC system.
