6.1. Power connection
Caution:
 Only connect the unit to a power socket with an earthing contact (PE – protective
earth)!
 The power supply plug serves as a safe disconnecting device from the line and
must always be easily accessible.
 Never operate the unit with a damaged mains power cable.
 Regularly check the mains power cables for damage.
 We disclaim all liability for damage caused by incorrect line voltages!
Make sure that the line voltage and frequency match the supply voltage
specified on the type plate.
