2.2 Notes about operation in potentially explosive areas
2.2.1 Special conditions (ATEX)
WARNING
Danger of explosion
Gases or dusts can be ignited in potentially explosive areas. Read and follow the safety instructions to pre-
vent deflagration or explosions.
The Panel PC must be installed in a housing, which ensures protection class IP54 for gas according to EN
60079-7.
A housing with protection class IP54 is required for fibers and flyings, and for non-conductive dust. IP6X is
required for conductive dust according to EN 60079-31.
Provisions shall be made to prevent the rated voltage from being exceeded by transient disturbances of
more than 119 V.
If the temperatures during rated operation are higher than 70 °C at the feed-in points of cables, lines or
pipes, or higher than 80°C at the wire branching points, then cables must be selected whose temperature
data correspond to the actual measured temperature values.
Observe the permissible ambient temperature during operation in potentially explosive areas. The
permissible ambient temperature range during operation is 0 °C to +55 °C.
The connections of the Panel PC may only be connected or disconnected if the supply voltage has been
switched off or if a non-explosive atmosphere is ensured.
Switch off the power supply and ensure that no explosive atmosphere occurs when the CFast card is
replaced.
Fix the USB cables with cable straps to the mounting bracket. Check tensile strength of the cables regularly
and retightened the cable straps if necessary.
The Panel PC may only be mounted horizontally (see: Mounting [
}
21] ).
