Supply voltage
Note:
The supply voltage is electrically isolated from the housing.
WARNING
ELECTRIC SHOCK
Only connect a supply voltage as described in the data plate of your device.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
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).
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
page 34.
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.
Voltage Supply: the wire diameter for the input supply line is
20AWG~12AWG.
The cross-section of the protective conductor cable is the same size as or
bigger than the cross-section of the voltage supply cables.
The connection cables used are permitted for the specified temperature
range.
