Ground Wiring
Follow the precautions below when wiring the ground for one drive or a series of drives.
WARNING!
Electrical Shock Hazard. Make sure the protective earthing conductor complies with technical standards and local safety
regulations. Because the leakage current exceeds 3.5 mA in models 4A0414 and larger, IEC 61800-5-1 states that either the power supply
must be automatically disconnected in case of discontinuity of the protective earthing conductor or a protective earthing conductor with a
cross-section of at least 10 mm
2
(Cu) or 16 mm
2
(Al) must be used. Failure to comply may result in death or serious injury.
WARNING!
Electrical Shock Hazard. Always use a ground wire that complies with technical standards on electrical equipment and minimize
the length of the ground wire. Improper equipment grounding may cause dangerous electrical potentials on equipment chassis, which could
result in death or serious injury.
WARNING!
Electrical Shock Hazard. Be sure to ground the drive ground terminal (200 V class: ground to 100 Ω or less; 400 V class: ground
to 10 Ω or less; 600 V class: ground to 10 Ω or less). Improper equipment grounding could result in death or serious injury by contacting
ungrounded electrical equipment.
NOTICE:
Do not share the ground wire with other devices such as welding machines or large-current electrical equipment. Improper
equipment grounding could result in drive or equipment malfunction due to electrical interference.
NOTICE:
When using more than one drive, ground multiple drives according to instructions. Improper equipment grounding could result in
abnormal operation of drive or equipment.
when using multiple drives. Do not loop the ground wire.

Wiring the Main Circuit Terminal
WARNING!
Electrical Shock Hazard. Shut off the power supply to the drive before wiring the main circuit terminals. Failure to comply may
result in death or serious injury.
Wire the main circuit terminals after the terminal board has been properly grounded.
Models 2A0004 to 2A0081, 4A0002 to 4A0044, and 5A0003 to 5A0032 have a cover placed over the DC bus and braking
circuit terminals prior to shipment to help prevent miswiring. Use wire cutters to cut away covers as needed for terminals.
