Extended storage
If the unit is being stored for a long time, connect it to the mains voltage for at least 5
minutes every 2 years. Otherwise, the unit’s service life may be reduced.
The 24 V DC voltage supply can be applied without paying attention to any particular
notes.
Procedure when maintenance has been neglected:
Electrolytic capacitors are used in the servo inverters. They are subject to aging effects
when deenergized. This effect can damage the capacitors if the unit is connected using
the rated voltage after a longer period of storage.
If you have not performed maintenance regularly, SEW-EURODRIVE recommends that
you increase the supply voltage slowly up to the maximum voltage. This can be done,
for example, by using a variable transformer for which the output voltage has been set
according to the following overview.
The following stages are recommended:
AC 400/500 V units:
• Stage 1: 0 V to AC 350 V within a few seconds
• Stage 2: AC 350 V for 15 minutes
• Stage 2: AC 420 V for 15 minutes
• Stage 3: AC 500 V for 1 hour
After you have completed the regeneration process, the unit can be used immediately
or stored again for an extended period with maintenance.

Please follow the current national regulations.
Dispose of the following materials separately in accordance with the country-specific
regulations in force, as:
• Electronics scrap (printed-circuit boards),
• Plastic,
• Sheet metal,
