6.4 Shutdown
The motor is only regarded as being shut down if the frequency inverter is de-
energised.
Simply switching the frequency inverter to the "OFF" position does not provide
reliable protection against unintentional restart.
1. Completely de-energise the drive.
6.5 Idle periods
Extended idle periods (> 1 month)
For extended idle periods (> 1 month), start up the drive regularly (e.g. once per
month), or at least turn the rotor. For motors with a transport lock, remove the lock
prior to turning the rotor. Before you start the drive, read the information in section
"Returning to service". (

Section 6.2, Page 29)
If you plan to take the drive out of service for more than 12 months, implement
appropriate corrosion protection, preservation, packaging and drying measures.
6.6 Returning to service

Returning to service only in conjunction with a frequency inverter, e.g. PumpDrive 2
or PumpDrive R
