Mounting Recommendations; Space Around Antennas (Plastic) - Advantech LR77 v2 Libratum User Manual

5.5 Mounting recommendations

• possibility to be put on a work surface,
• DIN rail EN 60715 with included plastic or metal clip.
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 follow-
ing there is no need to have examination immunity or issues in connection with EMC according
to EN 60439-1 ed.2:00 + A1:04.
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 due to the elimination of interference. While using an external
antenna except for the switch-board it is necessary to fit a lightning conductor.
• Before mounting a router on sheet-steel we recommend using a cable antenna.
