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 endange-
red by gas explosions.
•
Please note: The ANT2-M is classified as „simple apparatus“ as there is no ignition risk just by
the anten-
na. 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.
Operating manual of data acquisition system PWBlogg
• If the data logger is supplied by external voltage, the power supply unit delivered by manufacturer must
exclusively be used. This is always connected with the supply voltage outside of the explosion-hazard
area. Use the power supply unit only at the intended supply voltage. Supplying the data logger using
different power supply units and additional equipment is not permitted.
• If the device is equipped with a lithium ion battery, charging this battery must be done outside the poten-
tially explosive areas.
• For integration into the system‘s potential equalization use the dedicated port at the data logger‘s case.
Note:
The data logger‘s battery circuit is operatively grounded at its case.
Any subsequent modification to the device results in the consequence that a secure use
is no more
guaranteed within ex-zone 2 and the EC declaration of conformity loses ist validity.
