
Supply voltage
Note: The supply voltage is electrically isolated from the housing.

For every supply voltage to be connected, make sure the following
requirements are met:
 The power supply conforms to overvoltage category I or II.

The voltage supply has an easily accessible disconnecting device
(e.g. a switch or a plug). This disconnecting device is clearly
identified so that in the case of an emergency, it is clear which
disconnecting device belongs to which line.
 The disconnecting device is clearly identified so that in the case of
an emergency, it is clear which disconnecting device belongs to
which line.
 The lines to be connected are voltage-free.

The ground screw on the back of the device is connected to the
protective conductor.
 There is a fuse in the outer conductor (AC) or the positive
conductor (DC) of the voltage supply.
Regarding the properties of this fuse: See “General technical data”
on page 52.

Supply with DC voltage: the fuse is suitable for a DC voltage.
 If the neutral conductor (AC) or the negative conductor (DC) is not
grounded: there is a fuse in each of the two wires.
 AC voltage Supply: the wire diameter for the input supply line is at
least 0.75 mm² (North America: AWG18).
WARNING
