Danger to life from electric shock
Contact with exposed and live elements generate an electric shock. Incorrect connection of the mains
supply leads to the risk of live housing parts that can be touched. There is a risk to life.
►Before the installation, check that the connection leads are voltage-free.
►Make sure that electrical installations are only carried out by qualified electricians.
►Provide adequate grounding for the device.
►After connection work, carry out an earthed conductor check.
