Possibility to be put on a work surface,
DIN rail EN 60715 with included clip CPD3 (or CKD2 for metal version).
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 61439-1:2011.
Compliance of EN 61439-1:2011 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.
For every cables we recommend to bind the bunch, we recommend for this use:
– Length of the bunch (combination of power supply and data cables) can be maxi-
mum 1.5 m. If the length of data cables exceeds 1.5 m or in the event of, the cable
leads towards the switch – board. We recommend installing over – voltage protec-
tors (surge suppressors).
