Electromagnetic compatibility
Notice
The user must ensure compliance with EMC Directive 2014/30/EC using appropriate controls
and switching devices.
NOTICE
If an INTORQ rectifier is used for the DC switching of the spring-applied brake and if the
operating frequency exceeds five switching operations per minute, the use of a mains filter
is required.
If the spring-applied brake uses a rectifier of another manufacturer for the switching, it
may become necessary to connect a spark suppressor in parallel with the AC voltage.
Spark suppressors are available on request, depending on the coil voltage.

Emissions
Heat
Since the brake converts kinetic energy as well as mechanical and electrical energy into heat, the surface
temperature varies considerably, depending on the operating conditions and possible heat dissipation. Un-
der unfavourable conditions, the surface temperature can reach 130 °C.
Noise
The loudness of the switching noise during engaging and disengaging depends on the air gap "s
L
" and the
brake size.
Depending on the natural oscillation after installation, operating conditions and the state of the friction sur-
faces, the brake may squeak during braking.
Others
The abrasion of the friction parts produces dust.
