9.8 Extended storage
Electrolytic capacitors are used in the frequency inverters. They are subject to aging
effects when de-energized. If the device is connected to the voltage supply directly
after a long storage period, the capacitors can be damaged.
In case of extended storage, connect the device to the supply voltage for at least 5
minutes every 2 years. Otherwise, the service life of the device may be reduced.
If you have not performed maintenance regularly every 2 years, 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:
• Step 1: AC 0 V to AC 350 V within a few seconds
• Step 2: AC 350 V for 15 minutes
• Step 3: AC 420 V for 15 minutes
• Step 4: AC 500 V for 1 hour
9.9 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 (circuit boards)
• Plastics
• Sheet metal
• Copper
• Aluminum
