Conformity; Safety Instructions - NetModule NB3711 User Manual

2. Conformity

This chapter provides general information for putting the router into operation.

2.1. Safety Instructions

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.
We would like to point out that only the original accessories, shipping with the router,
must be used in order to prevent possible injury to health or damage to appliances and
to ensure that all the relevant provisions have been complied with. Unauthorized mod-
ifications or utilization of unapproved accessories may void the warranty. The routers
must not be opened. However, it is possible to replace any pluggable SIM cards even
during operation.
All circuits connected to the interfaces of the router must comply with the requirements
of Safety Extra Low Voltage (SELV) circuits and have to be designed for indoor use only.
Interconnections must not leave the building nor penetrate the body shell of a vehicle.
Possible antenna circuits must be limited to over-voltage transient levels below 1 500 V
DC
(according to IEC 60950-1, TNV-1 circuit levels) by using safety approved components.
NB3711 routers shall only be used with a certified (CE or equivalent) power supply
1
which must have a power limited and SELV circuit output.
They are basically designed for indoor use. Do not expose the communication module
to extreme ambient conditions and protect the communication module against dust,
moisture and high temperature.
We remind the user of the duty to observe the restrictions concerning the utilization of
radio devices at petrol stations, in chemical facilities or in the course of blasting works
in which explosives are used. Switch off the communication module when traveling by
plane.
You need to pay increased attention when using the communication module close to
personal medical devices, such as cardiac pacemakers or hearing aids. NetModule routers
may also cause interference in the nearer distance of TV sets, radio receivers and personal
computers.
Avoid any installation of the antenna during a lightning. Always keep a distance of more
Note: Power supplies for routers with the Pb option (72-110 V ) cannot be a SELV circuit, since
