10.2.1 Extended storage
If the unit is stored for a long time, connect it to the supply voltage for at least 5 mi-
nutes every 4 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 deenergized. This effect can damage the capacitors if the unit is connected di-
rectly to the nominal voltage after a longer period of storage.
If maintenance has been neglected, SEW‑EURODRIVE recommends to connect the
unit to a MOVITRANS
®
supply with reduced line cable current. To do so, set the nomi-
nal line cable current parameter in the MOVITRANS
®
supply according to the following
overview to slowly increase the internal voltage supply.
The following stages are recommended:
• Stage 1: Power on with 50% of the line cable current
• Stage 2: 50% line cable current for 15 minutes
• Stage 3: 75% line cable current for 15 minutes
• Stage 4: 100% line cable current for 1 hour
