Handling Precautions

If electrical interference proves excessive, we recommend adding an insulating transformer and/or using a line filter.

model No.: 81446364-001

After carrying out interference reducing measures, do not bundle the primary and secondary power supply coils together or insert them in the same conduit or duct.

Grounding

If grounding the shield wire or other lines proves difficult, ground them separately

to a grounding terminal block.

 

 

Type

: A ground resistance of maximum 100
