Safe Transportation and Storage

Follow all information on transportation, storage, and proper handling given in the product-specific documentation. That includes:
If the drive is stored before installing it, make sure that the ambient conditions agree to the specifications given in
l
Conditions during Storage.
If the package is kept in storage for more than 4 months, keep it in controlled conditions:
l
Make sure that the temperature variation is small.
¢
Make sure that the humidity is less than 50%.

Reforming guideline
No reforming required. Connect to mains voltage.
Connect to mains voltage and wait a minimum of 30 minutes before loading the drive.
Using a DC supply connected directly to the DC-link terminals of the drive, ramp up the voltage 0–
100% of DC-bus voltage in increments of 25%, 50%, 75%, and 100% rated voltage under no load for
30 minutes at each increment. See
