Beware, danger of life!
Parts of the controller card are on the intermediate circuit voltage (up to
48V DC) and result in live voltage for about 5 minutes after deactivating
the current.
Touching the terminals, lines and device parts can cause serious injury or
death!
7.3. EMC measures
Ensure that the controller devices are suitable for use in the required EMC
environment.
EPH Elektronik supplies special mains filters and bodies aligned with the respective
controller which guarantee a best possible stability noise immunity, low
interference emission, simple assembly and installation as well as the required
electric safety.
EMC security is, however, only provided if, apart from an EMC-suitable housing and
the recommended mains filter, a proper installation with shielded motor and control
lines between the super ordinate control, controller and motor is adhered to.
The shield must be earthed on the biggest possible scale and using the shortest
route. The shield must be laid on the housing using a respective metal fitting for
housing executions.
• Remove the varnish and the insulation between the
installation points
• Ensure largest possible scales of metal connections
• Anodised or yellow dichromated surfaces have a high HF
resistance, this is why the surface must be sanded down
accordingly.
• Cables to the controlling device should be as short as
possible and laid separately from other mains lines
