All wiring must comply with local and national regulations regarding cross-
section and ambient temperature requirements.
Power connection wire recommendation: minimum 167°F [75°C] rated copper
wire.
Ensure correct grounding of the equipment by a certified electrical installer.
Ground the adjustable frequency drive in accordance with applicable standards
and directives.
Use a dedicated ground wire for input power, motor power and control wiring.
Do not ground one adjustable frequency drive to another in a "daisy chain"
fashion.
Keep the ground wire connections as short as possible.
Follow the motor manufacturer wiring requirements.
Minimum cable cross-section: AWG 7 [10 mm
terminated separately).
Establish electrical contact between cable shield and adjustable frequency
drive enclosure by using metal cable connectors or by using the clamps
provided on the equipment (see Chapter 4.6 Motor Connection).
Use high-strand wire to reduce electrical interference.
Do not use pigtails.
