11.9.3 Electronics
If the unit is 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.
Procedure when
maintenance has
been neglected
Electrolytic capacitors are used in the inverters. They are subject to aging effects when
de-energized. 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 line 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. After you
have completed the regeneration process, the unit can be used immediately or stored
again for an extended period with maintenance.
The following stages are recommended:
AC 400/500 V units:
• Stage 1: AC 0 V to AC 350 V within a few seconds
• Stage 2: AC 350 V for 15 minutes
• Stage 3: AC 420 V for 15 minutes
• Stage 4: AC 500 V for 1 hour
11.10 Disposal
Observe the current regulations: Dispose in accordance with the material structure and
the regulations in force for instance as:
• Aluminum scrap
