Connecting the Input and Output Circuits
Connect the input and output circuits using pluggable terminals located on the device's front
plate.
Do not plug the terminals for output circuits if a load is connected. If short-circuits are present,
the resulting high current may damage the terminals.
To attach the shielding to the shield contact plate with a clamp, it is useful to lead the shielded
cables from below to controllers with analog inputs. To this end, place the clamp over the
surface of the stripped cable shielding and press it from both sides into the oblong holes of the
shield contact plate until it snaps into position.

Earthing and Shielding
7.2.5.1
Earthing the 24 VDC System Voltage
All devices of the HIMatrix family must be operated with power supply units that comply with the
SELV (Safety Extra Low Voltage) or PELV (Protective Extra Low Voltage) requirements. A
functional earth is prescribed to improve the electromagnetic compatibility (EMC).
All HIMatrix systems can be operated with earthed L- or unearthed.
Unearthed Operation
Unearthed operation offers some advantages in terms of EMC behavior.
Some applications have specific requirements for the unearthed operation of controllers, e.g., in
accordance with the VDE 0116 standard, earth fault monitoring is required for unearthed
operation.
Earthed Operation
The earth must be designed in accordance with the standard and must have a separate earth
contact through which no power-dependent interference current may flow. Only earthing of
negative pole (L-) is permitted. Earthing of positive pole (L+) is not permitted since a potential
earth fault on the transmitter line would bypass the affected transmitter.
