approved by the manufacturer. The product can only be operated cor-
rectly and safely if it is transported, stored, installed and assembled pro-
perly and correctly. Furthermore, it must be operated and serviced

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 voltage supply conforms to overvoltage category II.
The voltage supply has an easily accessible disconnecting device
(e.g. a switch or a plug).
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:
When using a DC voltage supply: 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 on each of the two wires.
Supply with AC voltage: the wire diameter for the input supply line
is at least 0.75 mm² (North America: AWG18).
WARNING
ELECTRIC SHOCK
Only connect a supply voltage that corresponds to the type plate of your
device.
Failure to follow these instructions can result in death, serious injury,
or equipment damage.
