5.5 Start-up
Before starting the inverter, if components are condensed inside the inverter or have been stored in a highly
humid air for a long time, it has to be dried out enough for more than a day, otherwise it will cause failure. After
that the circuit breakers must be switched ON to start the inverter, which also switches on the control circuits.
DANGER
Lethal voltages are still present in the terminals and lines of the inverter even after
the inverter has been switched off and disconnected!
Coming into contact with the lines and terminals in the inverter will cause serious
injury or death.
Only authorised electricians who are approved by the supply grid operator may open,
install and maintain the inverter.
›
Keep all doors and covers closed when the unit is in operation.
› Do not touch the lines and terminals when switching the unit on and off!
