DESCRIPTION OF THE UR5 ROUTER

For the majority of applications with a built-in modem 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 modems to switch board,

the following it is not need have no examination immunity or issues in connection with EMC

according to EN 60439-1+A1.

For compliance of EN 60439 - 1 + A1 specification it is necessary observe next

assembly of the modem to the switch - board:

• round antenna 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 modem on sheet-steel we recommend using an external antenna,

• 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.
