4.1.3
Selecting the control unit
When selecting the control unit, it must always be clarified whether an explosion-proof
version is necessary or whether the control unit can also be installed in the safe area (
“Application illustration DUSTHUNTER SP100 Ex-3K”, page 36
). Please note that additional
precautions for explosion protection must be observed when connecting the control unit in
the Ex-area.
Selecting the MCUDH Ex-3K control unit
Selection of the MCUDH Ex-3K control unit depends on the required power supply unit and
the optional Interface module (
). The control units are suitable for
operation in Ex-zones 2/22.
Table 10: Selection Table for MCUDH Ex-3K control unit
Selecting a conventional MCU control unit
Selection depends on the type of power supply and the optional Interface modules (
). The conventional control units are not suitable for operation in Ex-
areas.
