NOTICE
The user must ensure compliance with EMC Directive 2014/30/EU using appropriate controls
and switching devices.
If an INTORQ rectifier is used for the DC switching of the spring-applied brake: If the switching frequency
exceeds five switching operations per minute, the use of a mains filter is required.
If the spring-applied brake uses a rectifier from another manufacturer for the switching, it may become nec-
essary to connect a spark suppressor in parallel with the AC voltage. Spark suppressors are available on
request, depending on the coil voltage.
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 switching noise during engagement and disengagement varies depending on the air gap, braking torque
and brake size.
Depending on the natural oscillation after installation, operating conditions and state of the friction surfaces,
the brake may squeak during braking.
Miscellaneous
The abrasion of the friction parts produces dust.
