5.6 Mounting recommendations

• Possibility to be put on a work surface,
• DIN rail EN 60715 with included metal clip.
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 follow-
ing 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 lightning 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 (the combination of power supply and data cables) can be
maximum 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
protectors (surge suppressors).
