Mounting Recommendations
Router can be placed:
•
on a flat surface,
•
on a wall (or other surface) using the side wings,
•
on a DIN rail EN 60715 with the included metal DIN rail 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 router to a switchboard, after which
there is no need to have examination immunity or issues in connection with EMC according to
EN 61439-1:2011.
Attention:
If the negative pole of the router is grounded, there is no protection against
reversed polarity! The only protection left is the fuse inside the device.
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
cables and metal surfaces on every side in order to avoid interference. When using
an external antenna seperate from the switchboard it is necessary to fit a lightening
conductor.
•
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 (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.
–
Data cables must not have a reticular tension of
∼
230 V/50 Hz or
∼
120 V/60 Hz.
•
Sufficient space must be left between individual connectors for the handling of cables,
•
To ensure correct functioning of the router we recommend the use of an earth-bonding
distribution frame for the grounding of the power supply of the router, data cables and
antenna within the switchboard.
