For the most of applications with a built- in router in a switch board it is possible to recognize
two kinds of environments:
no public and industry environment of low voltage with high interference,
public environment of low voltage without high interference.
For both of these environments it is possible to mount router to a switch board, the following
there is no need to have examination immunity or issues in connection with EMC according to
EN 60439- 1 ed.2:00 + A1:04.
If the negative pole of the router is grounded, there is no protection against reversed
polarity!
Compliance of EN 60439- 1 ed.2:00 + A1:04 specification it is necessary to observe next
assembly of the router to the switch – board:
For whip antennas we recommend to observe a distance of 6 cm from cables and metal
surfaces on every side due to the elimination of interference. While using an external
antenna except for the switch- board it is necessary to fit a lightening conductor.
Before mounting a router on sheet- steel we recommend using a "cable" antenna.
