Interference Suppression
DOK-CONTRL-CLM01.4LAP1-FK01-EN-P
These controls are designed as modular units to be built into a control
cabinet. The controls are electrically connected via connectors on the top
side of the unit.
Protection System:
Front Panel = IP 20
Electronics and Connectors = IP 20
The installation should offer a type of protection appropriate for the
environmental conditions, for protection of the unit especially against
deposits of metal dust, oil, moisture and strong electromagnetic
interference, as well as for maintaining the allowable ambient
temperature.
Max. allowable ambient temperature:
with natural air flow
with forced ventilation
at 3 m/s air speed
Min. allowable ambient temperature:
Local power loss = 45 W max.
These controls are exemplary in their resistance to network and switching
problems. However, the following rules must be followed during
installation, to eliminate excessive problem situations.
With electronic controls, no inductive loads should be moved without
appropriate interference suppression.
For operation with DC voltage, appropriate interference suppression is
achieved by the arrangement of free-wheeling diodes, and for operation
with AC voltage, it is achieved by the arrangement of type-specific,
standard RC interference suppression elements
inductance.
Only the interference suppression element that is arranged directly at the
inductance fulfills the intended purpose!
If this is not the case [installation directly at the inductance], more
interference actually results because of surges in the interference
suppression circuitry.
This general rule should be followed as closely as possible. It is far easier
to prevent interference than to eliminate the results of existing
interference.
