General Maintenance Work
10.4.1 Performing the Visual Inspection
Danger to life due to electric shock or electric arc if live components are touched
If the MV Power Station and its devices are not correctly disconnected, dangerous voltages may be present in the
components which, if touched, will result in death or serious injury.
• Disconnect the MV Power Station (see Section 7.6, page 101).
• After switching off the inverter, wait at least 15 minutes before opening it to allow the capacitors to discharge
completely.
• Ensure that the MV Power Station and its devices are voltage-free.
Procedure:
1. Ensure that there are no foreign materials or objects in or on the MV Power Station and its devices that are
flammable or that could otherwise endanger operational safety. If necessary, remove foreign materials and seal
any holes to prevent further intrusion.
2. Ensure that there are no objects under the medium-voltage compartment which endanger operational safety in
case of arc faults.
3. Ensure that there are no objects under the inverter compartment which prevent the air from circulating.
