Installation regulations, EMC
Observe the following requirements when installing a DMI in
a device or system:
• Always mount the DMI on an earthed top-hat rail.
• The clearance between the DMI and the circuit-breaker, as
well as between the DMI and the main conductors must
be at least 0.5 m.
• All cables and conductors connected to the DMI must not
be laid parallel to the main conductors. Conductors may
only be crossed on the shortest possible route and with a
minimum clearance of 10 cm.
• The minimum bending radius of the communication cable
between NZM and DMI is 130 mm.
• Fit the supplied ferrite ring on the cable (NZM-XDMI-CAB)
to the circuit-breaker approximately 5 to 10 cm from the
plug at the circuit-breaker end.

These measures must be observed in order to ensure the
EMC characteristics specified in a section
“Electromagnetic compatibility (EMC)”, Page 70.
