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
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 5.3.4). The maximum allowed gain is 3dBi in the re-
levant frequency range. WLAN antennas with a higher amplification may be used with
the NetModule router Ënhanced-RF-Configurationßoftware license and the antenna
gain and cable attenuation that have been correctly configured by certified 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 hea-
ring 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.
