Guidelines for EMC-compatible Installa-
tion
General:
For electronic equipment that supplies inductive loads
(such as electromagnetic safety brakes or clutches/cou-
plings), the prescribed measures regarding interference
emission as per the EMC directive can only be considered
in combination with the respective load and not only for the
equipment itself. The EMC directive can only be adhered to
by the complete device or machine.
The measures described for compliance with the EMC
directive for electronic equipment are examined under
laboratory conditions, and cannot necessarily be bindingly
transferred onto the condition of a machine or system in
case of deviations.
Scope of the inspection:
• Monitoring module ROBA
®
-brake-checker
• released ROBA
®
-stop safety brake
Interference immunity:
The interference immunity as per the stated standards is
achieved without additional measures.
Interference emission:
The line filter must be installed before the control element
on the mains side (see wiring example on Page 5)
• Observation of the requirements of the
standard IEC 60364-4-44/VDE0100-444
• Observation of the remarks/guidelines/in-
structions of the control cabinet, line filter
and frequency converter manufacturer
regarding EMC-compliant setup
• Observation of the EMC guidelines from
ZVEI and DEMVT
• Observation of the recommendations of
the IEC TR 61000-5-2
• Mains, power, measurement, signal and
control lines laid separately
• Possibly use shielded, separate line per
brake
• Line shielding must be EMC compliant
and have the greatest possible surface
area
• Ensure good earth connections on the
metal body of the brake
• Avoid antennae effects: Keep lines as
short as possible; do not form rings or
loops
• Signal lines over 30 m are considered
long lines and may require special mea-
sures
• According to IEC 618003, IT networks
are “second environment” category C4
and require special measures
• Equipment with interference emission
levels for industrial usage (environment/
class A, second environment) may re-
quire additional measures when used for
domestic purposes (environment/class B,
first environment)
