Conformity; Safety Instructions - NetModule NB2710 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 modifications 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 (according to IEC 60950-1, TNV-1
DC
circuit levels) by using safety approved components.
NB2710 routers shall only be used with a certified (CE or equivalent) power supply which must
have a power limited and SELV circuit output.
They are basically designed for indoor use. Do not expose the communication module to ex-
treme 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 than 40
cm from the antenna in order to reduce exposure to electromagnetic fields below the legal limits.
This distance applies to - and -antennas. Larger distances may apply to antennas with higher
4 2
gain.
Any Ethernet cabling must be shielded, the Ethernet section of this manual provides more infor-
mation.
Devices with a WLAN interface may be operated only with applicable Regulatory Domain config-
ured. Special attention must be paid to country, number of antennas and the antenna gain (see
also chapter 5.3.4). 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.
If an extension cable is used to attach the antenna, the antenna gain may be higher by the amount
of cable attenuation. The user is responsible for the compliance with the legal regulations.
We highly recommended creating a copy of a working system configuration. It can be downloaded
using the Web Manager and easily applied to a newer software release afterwards as we generally
guarantee backward compatibility.
