Release 08 01/2019
Certified usage
Use the product only for the application cases described in the
Hirschmann product information, including this manual.
Operate the product only according to the technical specifications.
See “Technical data” on page 37.
Connect to the product only components suitable for the requirements
of the specific application case.
National and international safety regulations
Verify that the electrical installation meets local or nationally applicable
safety regulations.
Grounding the device
The device is grounded via the power supply connections.
Requirements for connecting electrical wires
Before connecting the electrical wires,
always
verify that the
requirements listed are complied with.
Requirements for connecting the supply voltage
Before connecting the supply voltage,
always
verify that the requirements
listed are complied with.
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.
Only switch on the device when the casing is closed.
Relevant for North America:
Exclusively use 60/75 °C (140/167 °F) or 75 °C (167 °F) copper (Cu) wire.
Prerequisites:
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.
This applies to the following device variants only:
MACH104-20TX-FR...
Unplug every non-heating device coupling to disconnect the device from the power supply.
This applies to the following device variants only:
MACH104-20TX-FR...
The wire diameter of the power supply cable is at least 1 mm² (North America: AWG16) on
the supply voltage input.
The cross-section of the ground conductor is the same size as or bigger than the cross-
section of the power supply cables.
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:
