■ Ground Wiring
Follow the listed precautions to properly wire the ground for one drive or a series of
drives.
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 W or less, 400 V Class: Ground to 10 W 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.
Refer to Figure 3.15 when using more than one drive. Do not loop the ground wire.
