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 conguring 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.
• Allsubsequentmodicationstothedeviceresultintheconsequencethatasecureuse
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 classied 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.
