by the user. Fuses inside the device may only be replaced by authorized staff, such as
your specialist dealer.
Power supply

must not be rendered ineffective. Furthermore, the device may only be connected to
an outlet with a functioning protective conductor connection.
The device has a power supply unit that automatically adjusts to the power supply.
As a result, the device can be operated with all common power supplies.

damaged power cord. Instead, switch the device off and contact your specialist dealer.
Disconnecting the device from the power supply
To disconnect the Phase 3 from the power supply completely, use the easy-to access
mains switch on the rear panel. After doing so, please disconnect the plug of the power
cord from the device.

Operation during thunderstorms
During thunder and lightning storms, disconnect the device from the power supply by
