DIN rail with clips CPD2 (Elpac clip SL for SL version) are included
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
60439-1 ed.2:00 + A1:04.
•
For compliance of EN 60439-1 ed.2:00 + A1:04 specification it is necessary to observe next assem-
bly of the router to the switchboard.
•
For whip antennas we recommend to observe a distance of 6 cm from cables and metal surfaces
on every side according to the next picture 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 an external antenna.

For multiple cables, we recommend to bind the bunch according to the following picture. We recom-
mend for this use:
•
Length of the bunch (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 switchboard,
we recommend installing over-voltage protectors (surge suppressors).
•
Keep a distance of 50 mm between data cables and power supply cables with
~ 230 V/50 Hz
.
•
All signals to sensors must be twisted pairs
