8.7 How to check Power Components

Before checking the power components, be sure to disconnect AC Input Supply and wait until the Main Electrolytic

Capacitor (B+ - B-) discharges.

•

NOTE:

If the drive has been powered-off for more than two years, it is strongly recommended that the drive be sent

back to the factory to recondition the electrolytic capacitors.
