Mounting Recommendations
•
possibility to be put on a work surface,
•
DIN rail EN 60715 with included clip CKD-SBD23.
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.
It is possible to mount the router to a switch board ror both of these environments. Then
there is no need to perform any immunity or emission test in relation to EMC according to EN
61439-1:2011.
For complying with EN 61439-1:2011 standard is necessary to observe the following
router installation into switchboard:
•
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).
–
With data cables they mustn’t carry cables with reticular tension
∼
230 V/50 Hz.
•
Sufficient space must be left in front of individual connectors for handling of cables,
•
For correct function of the router we recommend to use in the switch-board earth-bonding
distribution frame for grounding of power supply of router, data cables and antenna.
