User Manual for NRSW version 4.5.0.100
Information about the device interfaces:
– All systems that are connected to the NetModule router interfaces must meet the
requirements for SELV (Safety Extra Low Voltage) systems.
– Interconnections must not leave the building nor penetrate the body shell of a vehicle.
– Connections for antennas may only exit the building or the vehicle hull if transient
overvoltages (according to IEC 62368-1) are limited by external protection circuits
down to 1 500 V
peak
. All other connections must remain within the building or the vehicle
hull.
– Always keep a distance of more than 40 cm from the antenna in order to reduce
exposure to electromagnetic fields below the legal limits.
– Devices with a WLAN interface may be operated only with applicable Regulatory Do-
main configured. Special attention must be paid to country, number of antennas and
the antenna gain (see also chapter
). The maximum allowed gain is 3dBi in
the relevant frequency range. WLAN antennas with a higher amplification may be
used with the NetModule router "Enhanced-RF-Configuration" software license and
the antenna gain and cable attenuation that have been correctly configured by certi-
fied specialized personnel. A misconfiguration will lead to loss of the approval.
– Cellular antennas attached to the router must have an antenna gain of equal or less
than 2.5 dBi. The user is responsible for the compliance with the legal regulations.
– Only CE-compliant power supplies with a current-limited SELV output voltage range
may be used with the NetModule routers.
General safety instructions:
– Observe the usage limitations of radio units at filling stations, in chemical plants, in
systems with explosives or potentially explosive locations.
– The devices may not be used in airplanes.
– Exercise particular caution near personal medical aids, such as pacemakers and hear-
ing aids.
– The NetModule routers may also cause interference in the nearer distance of TV sets,
radio receivers and personal computers.
– Never perform work on the antenna system during a thunderstorm.
– The devices are generally designed for normal indoor use. Do not expose the devices
to extraordinary environmental conditions worse than IP40.
– Protect them against aggressive chemical atmospheres and humidity or temperatures
outside specifications.
– We highly recommended creating a copy of a working system configuration. It can be
easily applied to a newer software release afterwards.
