1.1 Mains power supply
Danger to life from electric shock
Inadequate or incorrect grounding of the unit leads to contact-sensitive voltage on the housing. When
making contact, increased leakage currents will cause a life-threatening electric shock.
► Before the installation, check that the connection leads are voltage-free.
► Conduct the electrical connection in accordance with locally applicable regulations.
► Make sure that the local mains voltage and frequency match rating plate specifications.
► Make sure that the mains cable and extension cable meet the requirements for double isolation
► Use only a 3-pin mains cable and extension cable with properly connected protective earthing
