WARNING
High leakage currents exist in AC line filters. The filters must
be grounded properly before applying power. Filter capaci-
tors retain high voltages after removal. Measure voltages to
determine safe levels prior to handling the equipment. Fail-
ure to do so could result in severe bodily injury.
NOTE
To be able to route the interference currents at low impedance back to
the interference sources, the filter, the power unit, and the contact area
of the motor cable shield must have a junction with the common mount-
ing plate over as wide a surface as possible that has good conductive
properties. The best way to ensure this is to use unpainted zinc-coated
mounting plates.
