Shutdown
WARNING
Electric shock due to charged capacitors.
Severe or fatal injuries.
•
Observe a minimum switch-off time after disconnecting the power supply:
10
minutes.
To shut down the device, disconnect it from the power supply using appropriate meas-
ures.
10.7
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" (→
10.8
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
