Installation
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
.

DANGER!
• Hazard of electrical shock! Circuit potentials are up to 240 VAC above earth ground. Capacitors retain
charge after power is removed. Disconnect power and wait until the voltage between B+ and B- is
0 VDC before servicing the 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 three minutes. Damage to the drive will result.
STOP!
If the kVA rating of the AC supply transformer is greater than 10 times the input kVA rating of the drive(s),
an isolation transformer or 2-3% input line reactor must be added to the line side of the drive(s).
