Switchgear mains connection
DANGER
Danger of death due to electrical current when the main switch is switched off!
Even when the main switch is switched off, there is mains voltage power to the voltage selection terminal.
- Make the voltage selection before connecting the product to the mains.
CAUTION
Risk of property damage due to incorrectly set mains voltage!
If the wrong mains voltage is set, the switchgear will be destroyed. The switchgear can be operated at different mains voltages. The mains voltage is set to 400 V at the factory.
- To use another mains voltage, change the position of the cable jumper before connection.
