◆ Ground Wiring
Follow the precautions below when wiring the ground for one regenerative unit or a series of regenerative units.
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 regenerative unit ground terminal (200 V class: ground to 100
Ω or less;
400 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 regenerative unit or equipment malfunction due to electrical interference.
NOTICE: When using more than one regenerative unit, ground multiple regenerative units according to instructions. Improper
equipment grounding could result in abnormal operation of regenerative unit or equipment.
