General

Keep control wiring as far away as possible from the power wiring and in separate conduits
to avoid interference. If necessary let them cross only at 90º angle.

The AC motor drive control wiring should be properly installed and not touch any live power
wiring or terminals.
NOTE

If a filter is required for reducing EMI (Electro Magnetic Interference), install it as close as
possible to AC drive. EMI can also be reduced by lowering the Carrier Frequency.

When using a GFCI (Ground Fault Circuit Interrupter), select a current sensor with sensitivity
of 200mA, and not less than 0.1-second detection time to avoid nuisance tripping. For the
specific GFCI of the AC motor drive, please select a current sensor with sensitivity of 30mA
or above.
DANGER!
Damaged insulation of wiring may cause personal injury or damage to circuits/equipment if it
comes in contact with high voltage.
