1 Introduction
The PWB iModem is designed for remote data transmission for PWB-data loggers. Different protocols can be
used for data inquiry. The parameterization of the modem is done by the software PWB-Soft.

General safety instructions
• This device must only be installed and operated in compliance with the instructions and warning notices
of the dedicated technical documentation.
•
Only qualified personnel must install and operate this device.
• The data logger‘s power supply is done by a lithium primary battery. This can optionally be done by a
power supply unit too. In this case the internal lithium battery supplies the data logger during temporary
power failure.
Please note the following safety advice before you install and operate the devices:
• The power supply units and batteries delivered by manufacturer must exclusively be used. Failure to do
so may result in severe damage and accidents.
• Please pay attention to intactness of all connection cables. If there are cable damages, put the device out
of operation immediately. Contact maufacturer for repair.
•
Do not charge lithium batteries, throw them into fire or expose them to heat, as this can lead to battery
explosion and result in personal injury and/or material damage.
•
If fluid from battery pack gets into your eyes, rinse them with plenty of water and see a doctor.
• Never use water to extinguish burning batteries! EXPLOSION HAZARD!
• Do not use damaged batteries!
• Do not short-circuit batteries!

• Mounting and connecting the device must only be done if there is no potentially explosive atmosphere.
•
This device must only be used in areas with pollution level 2 as defined in IEC60991-1.
•
This device is only suitable in areas with low risk of mechanical hazards.
•
Connecting and disconnecting the plug connectors (antenne too) are only permitted if there is no explo
-
sive atmosphere. Operating the moden without antenna is not permitted.
• Unplugged connectors are not permitted in hazardous areas. Always remove unplugged connectors from
hazardous areas!
•
Opening the case (e.g. for battery change) must only be done if there is no potentially explosive atmo
-
sphere.
•
The case must only be cleaned by using wet cloths, otherwise there is the danger of spark ignition by
electrostatic discharge.
•
The „online outlet“ for data transmission and data logger configuration must only be used in case of no
-
nexistence of an explosive atmosphere. If not used, the „online outlet“ must be closed with the dedicated
cap.
•
If the online outlet is permanently used, make sure that the connected devices are with voltage rating no
more than 60V AC or 75V DC. Furthermore make sure that there is a transient protection and that it is set
to a value that does not exceed 140% of the rated voltage.
Attention:
The electronics consist of electrostatic sensitive components. Pay attention to ESD-
operation instructions when handling this electronics!
