9.7 Shutdown
WARNING
Electric shock due to charged capacitors.
Severe or fatal injuries.
• Observe a minimum switch-off time after disconnecting the supply voltage:
10 minutes.
To shut down the device, disconnect it from the power supply using appropriate mea-
sures.
9.8 Storage
Observe the following instructions when shutting down or storing the device:
• Cover the connections with the supplied protection caps.
• Place the device on a side without connectors.
• Ensure that the device is not subject to mechanical impact.
Observe the notes on storage temperature in chapter "Technical data" (→ 2 164).
9.9 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
