10.1.7 Extended storage
If the unit is stored for a long time, connect it to the power supply 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 frequency inverters. They are subject to aging
effects when de-energized. This effect can damage the capacitors if the unit is con-
nected directly to the nominal 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.
• 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
10.1.8 Waste disposal
Observe the applicable national regulations. Dispose of materials separately in ac-
cordance with the nature of the materials and the regulations in force, for example:
• Electronics scrap (printed circuit boards)
• Plastic
• Sheet metal
• Copper
• Aluminum
