5.6 Mounting Recommendations

• It is possible to place the router on a flat surface,
• DIN rail EN 60715 with the included plastic or metal clip.
For most applications with a built-in router within a switchboard, it is possible to recognize
two kinds of environments:
• A non-public, industry environment of low voltage with high interference,
• a public environment of low voltage and without high interference.
For both of these environments, it is possible to mount the router to a switchboard, af-
ter which there is no need to have examination immunity or issues in connection with EMC
according to EN 61439-1:2011.
In compliance with the EN 61439-1:2011 specification, it is necessary to observe the
following assembly instructions for a router attached to a switchboard:
• For whip antennas it is recommended to observe a minimum distance of 6 cm from ca-
bles and metal surfaces on every side in order to avoid interference. When using an
external antenna separate from the switchboard it is necessary to fit a lightning conduc-
tor.
• When mounting a router on sheet-steel we recommend using a cable antenna.
• For all cables, we recommend to bind the bunch, and for this we recommend:
– The length of the bunch (the combination of power supply and data cables) should
be a maximum 1.5 m. If the length of data cables exceeds 1.5 m or if the cable is
leading towards the switchboard, we recommend installing surge protectors.
