ER75s
For compliance of EN 60439-1 ed.2:00 + A1:04 specification it is necessary to observe
next assembly of the router to the switch – board:
•
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 interfer-
ence, 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,
Figure 4: Space around antennas
•
For every cables we recommend to bind the bunch according to the following picture,
we recommend for this use:
–
Length of the bunch (combination of power supply and data cables) can be max-
imum 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
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.
