Handling Precautions

If the power supply generates a lot of electrical noise, we recommend inserting an insulating transformer in the power circuit and using a line filter.

Recommended line filter: Model No. 81446364-001

After providing anti-noise measures, do not bundle primary and secondary power leads together, or pass them through the same piping or wiring duct.

Ground

When it is difficult to ground shielded cable, prepare a separate ground terminal (earth bar).

Ground type:

100

max.

 

Ground cable: 2mm sq. min soft-copper wire (AWG14)

Cable length:

Max. 20m
