User Manual for NRSW version 4.4
1. Welcome to NetModule
Thank you for purchasing a NetModule Router. This document should give you an introduction to the
router and its features. The following chapters describe any aspects of commissioning the device,
installation procedure and provide helpful information towards configuration and maintenance.
Please find further imformation such as sample SDK script or configuration samples in our wiki on
http://wiki.netmodule.com.

NB3720
User Manual for NRSW version 4.4
2. Conformity
This chapter provides general information for putting the router into operation.
2.1. Safety Instructions
Please carefully observe all safety instructions in the manual that are marked with the symbol .
Compliance information: The NetModule routers must be used in compliance with
any and all applicable national and international laws and with any special restrictions
regulating the utilization of the communication module in prescribed applications and
environments.
Information about the accessories / changes to the device:
– Please only use original accessories to prevent injuries and health risks.
– Changes made to the device or the use of non-authorized accessories will render the
warranty null and void and potentially invalidate the operating license.
– NetModule routers must not be opened (SIM cards may be used according to the
instructions).
10

NB3720
User Manual for NRSW version 4.4
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 Vpeak. 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 5.3.4). 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.1
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 IP65.
– 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.
1Note: Power supplies for routers with the Pb option (72-110 VDC) cannot be a SELV circuit, since the voltage is greater
than 60 VDC.

User Manual for NRSW version 4.4
2.2. Declaration of Conformity
NetModule hereby declares that under our own responsibility that the routers
comply with the relevant standards following the provisions of the RED Directive
2014/53/EU. The signed version of the Declaration of Conformity can be obtained
from http://www.netmodule.com/downloads
2.3. Waste Disposal
In accordance with the requirements of the Council Directive 2012/19/EU regard-
ing Waste Electrical and Electronic Equipment (WEEE), you are urged to ensure
that this product will be segregated from other waste at end-of-life and delivered
to the WEEE collection system in your country for proper recycling.
2.4. National Restrictions
This product may be generally used in all EU countries (and other countries following the RED Directive
2014/53/EU) without any limitation. Please refer to our WLAN Regulatory Database for getting further
national radio interface regulations and requirements for a particular country.
