2.7.4 Electrical safety
If covers are opened or parts are removed which are only accessible with tools, voltage-
carrying components may be exposed. The plugs may also be under voltage.

Electrical work must only be carried out by your authorized service partner.

Before connecting the device, check that the supply voltage and frequency are correct at
the point of installation (“Electrical data”, page 137 and the information on the type
plate, see “Marking and labelling of PrograMill One”, page 21).

To avoid injury to the user and for cooling reasons and fire protection, never remove the
housing covers.

Observe the manufacturer’s house installation instructions before installing (“Supporting
documents”, page 9).

To avoid the risk of electric shock, only connect the device to a power supply with a
protective earth conductor.

The mains plug is used as a supply circuit disconnecting means. Always connect the mains
plug to an easily accessible protective contact socket.

Connect the grounded and accessible safety contact socket to a separately secured circuit.

Make sure that the protective contact socket is equipped with a residual current circuit
breaker (FI).

Connect the machine to a separately secured circuit or make sure that no devices are
connected that cause severe supply voltage fluctuations when switched on. These
fluctuations interfere with the electronic controls and may cause failure of the system.

If you need to disconnect the unit from the power supply at a later time: Disconnect the
plug from the mains socket, not on the device.
