Chapter 2 Installation and Wiring|VFD-B Series
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.
