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.
