National and international safety regulations
Verify that the electrical installation meets local or nationally applicable
safety regulations.
Shielding ground
The overall shield of a connected shielded twisted pair cable is connected
to the ground connection on the metal housing as a conductor.
Beware of possible short circuits when connecting a cable section with
conductive shielding braiding.
Requirements for connecting electrical wires
Before connecting the electrical wires, always verify that the
requirements listed are complied with.
General requirements for connecting electrical wires
The following requirements apply without restrictions:
The electrical wires are voltage-free.
The cables used are permitted for the temperature range of the application case.
Ground the device via the ground screw.
Disconnect the grounding only after disconnecting all other cables.
Exclusively use 60/75 °C (140/167 °F) or 75 °C (167 °F) copper (Cu) wire.
The power supply cable to be connected is suitable for ambient air temperature of at least
212 °F (100 °C).
The power supply complies with the requirements for a safety extra-low voltage (SELV) as
per IEC/EN 60950-1.
Requirements for connecting the supply voltage
The following requirements apply without restrictions:
All of the following requirements are complied with:
The supply voltage corresponds to the voltage specified on the type plate of the device.
The power supply conforms to overvoltage category I or II.
The power supply has an easily accessible disconnecting device (for example 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.
The power supply cable is suitable for the voltage, the current and the physical load.
Hirschmann recommends a wire diameter of 0.5 mm² to 0.75 mm² (AWG20 up to AWG18).
The following requirements apply alternatively:
Relevant when the device is supplied via 1 voltage input:
Alternative 1
The power supply complies with the requirements for a limited power source
(LPS) as per EN 60950-1.
Alternative 2
Relevant for North America:
The power supply complies with the requirements according to NEC Class 2.
