For the majority of applications with a built-in router in a switch board it is possible to
recognize two sorts 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 routers to switch board,
the following it is not need have no 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 specifications it is necessary observe
next assembly of the router to the switch - board:
•
for single cables we recommend to bind the bunch according to the following picture,
for this use we recommend:
length of the bunch (combination of power supply and data cables) can
be maximum 1,5 m, if length of data cables exceeds 1,5 m or in the
event of, the cable leads towards the switch - board, we recommend to
use fit over - voltage protectors (surge suppressors),
with data cables they mustn't carry cables with reticular tension
~ 230 V/50 Hz,
all signals to sensors must be twisted pairs.
•
sufficient space must be left before individual connectors for handling of cables,
•
for correct function of the router we recommend to use in switch - board earth-
bonding distribution frame for grounding of power supply of router and data cables,
