Device variant
Requirements
All variants
All
of the following requirements are complied with:
The supply voltage corresponds to the voltage specified on the
type plate of the device.
The supply voltage conforms to overvoltage category I or II.
The supply voltage has an easily accessible disconnecting device
(e. g., a switch or a plug). This disconnecting device is clearly
identified. So in the case of an emergency, it is clear which
disconnecting device belongs to which power supply -cable.
A fuse is located in the outer conductor of the power supply.
The neutral conductor is on ground potential at both voltage
inputs. Otherwise, a fuse is also located in the neutral
conductor.
Regarding the properties of this fuse:
See Technical data on page 39
.
The power supply cable is suitable for the voltage, the current
and the physical load. The wire diameter is at least
0.75 mm²(North America: AWG18).

Requirements for connecting the supply voltage
WARNING
ELECTRIC SHOCK
Use only Safety Extra Low Voltage circuit.
Failure to follow this instruction can result in death, serious injury,
or equipment damage.
Supply voltage
The supply voltage is connected to the device casing through protective
elements exclusively.
Shielding ground
The overall shield of a connected shielded twisted-pair cable is
connected to the metal housing as a conductor.
Beware of possible short circuits when connecting a cable section
with conductive shielding braiding.
Grounding the device
Grounding the device is by means of a separate ground connection on the
device.
Ground the device before connecting any other cables.
Disconnect the grounding only after disconnecting all other cables.
