8.13.3 Electronics
INFORMATION
For electronics components, adhere to the following notes in addition to the notes in
chapters "Extended storage" > "Drive" and "Extended storage" > "Storage condi-
tions".
If the device is in extended storage, connect it to the line voltage for at least 5 minutes
every 2 years. Otherwise, the device's service life may be reduced.
Procedure in case 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 device is connected
directly to the nominal voltage after a longer period of storage. If you have not per-
formed maintenance regularly, SEW‑EURODRIVE recommends that you increase the
line voltage slowly up to the maximum voltage. This can be done, for example, by us-
ing a variable transformer for which the output voltage has been set according to the
following overview. After you have completed the regeneration process, the device
can be used immediately or stored again for an extended period with maintenance.
The following graduations 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
