Power Connections
DANGER!
Hazard of electrical shock! Circuit potentials are up to 600 VAC above earth ground.
Capacitors retain charge after power is removed. Disconnect power and wait at
least three minutes before servicing the drive.
STOP!
• Verify mains voltage before connecting to drive.
• Do not connect mains power to the output terminals (U,V,W)! Severe damage to
the drive will result.
• Do not cycle mains power more than once every two minutes. Damage to the
drive will result.

Installation After a Long Period of Storage
STOP!
Severe damage to the drive can result if it is operated after a long period of storage
or inactivity without reforming the DC bus capacitors.
If input power has not been applied to the drive for a period of time exceeding
three years (due to storage, etc.), the electrolytic DC bus capacitors within the
drive can change internally, resulting in excessive leakage current. This can result in
premature failure of the capacitors if the drive is operated after such a long period
of inactivity or storage.
In order to reform the capacitors and prepare the drive for operation after a long
period of inactivity, apply input power to the drive for 8 hours prior to actually
operating the motor.
