Connection and switching technology
Before carrying out maintenance or replacing the inverter, an installation must be de-energised by means of an isolation switch.
Safe shutdown of the installation
This service switch is clearly identifiable for unqualified persons and allows the entire installation to be de-energized. If the switch is not visible to the technician during work, it must be locked or marked with a warning sign. To indicate the presence of dangerous DC voltage, a label must be affixed to the DC connections on the equipment.
