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.
3.2.1
Power Connections
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).
DANGER!
Hazard of electrical shock!
Circuit potentials up to 600 VAC are possible. 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 may
result.
