1 Introduction

The PWB-iModem is designed for remote data transmission for PWB-data loggers (ELS, PWBlogg).
Different protocols can be used for data inquiry. The parameterization of the modem is done by the
software PWB-Soft.

2 General safety instructions

The power supply of data measure- and storage devices is provided by mains adapter. Some de­vice alternatives can also be supplied by lithium battery. Please consider following notes on safety
during operation of the devices:

• Use no other mains adapters and no other batteries or battery packs as supplied by manu­facturer or recommended ones, otherwise it can lead to serious damage of the device and to
accidents.

• Avoid mechanical damages of the electric cable of the mains adapter, as these can cause re or

electric shocks. Do not use damaged electric leads anymore.

• Do not recharge battery or battery pack or throw them into re or expose them to great heat,
as this can lead to an explosion of the batteries and can cause injuries to persons or material

damages.

• If a liquid of the battery pack reaches your eyes, rinse them immediately with a lot of water and
see a doctor.

Attention: The electronics consist of electrostatic sensitive components. Pay
attention to ESD-operation instructions when handling this electronics!

3 Safety instructions for use in Ex zone 2

The iModem is deliverable as operational supplement falling in category II 3 G for safe use within
explosive gas atmospheres of zone 2.
Please, pay attention to the following note on safety:

• The „online-outlet“ for data transfer and conguring iModem or data logger must be installed

outside of the explosion-hazard area. If the ‚online-outlet‘ is at the modem housing, this outlet
must only be used in case of nonexistence of an explosive atmosphere. When the system is not
used, the „online-outlet“ has to be closed using the protective cap.

• Devices must only be used with rating no more than 60V AC or 75V DC voltage, which prevent
the exceeding of rating even if a temporary interference of more than 40% occurs.

• If the iModem is supplied by external voltage, the mains-plug power supply delivered by manu­facturer must only be used. This is always connected to the mains outside of explosion-hazard
area. Do only use the AC-adapter at the mains voltage to be designed (230 VAC). Power supply
by using different mains adapters or accessory units are inadmissible.

• Opening the iModem e.g. for battery change must only be done outside of the explosion-hazard
area (in case of nonexistence of an explosive atmosphere).

• In case of damaged cables (data, transducer or ac power line), the device must not further be
operated. Please ask manufacturer for purpose of a repair.

• The antenna of the iModem is generally tted outside the Ex zone.

is no more guaranteed within Ex zone 2 and the EC-declaration of conformity loses its

validity.

4 Special notes on antenna use in Ex zone 2

• The ANT2-M is an antenna which is applicable when using a PWBlogg iModem in zone 2 areas
endangered by gas explosions.

• Please note: The ANT2-M is classied as „simple apparatus“ as there is no ignition risk just by

the antenna. Therefore ATEX markings are not permissible.

• The ANT2-M has been assessed together with the PWBlogg iModem to ensure that there is no
ignition risk by interconnecting both.

• If the iModem including a different antenna is supposed to be used in areas of the zone 2 endan­gered by gas explosions, the antenna must be installed outside any dangerous area or a risk
assessment must be conducted by manufacturer again.
