2.2 Notes about operation in potentially explsive 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.
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 +45 °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.
Switch off the power supply and ensure that no explosive atmosphere occurs when changing the battery of
the system clock.
The connectors on the backside of the Panel PC must be protected against mechanical damage either with
Beckhoff mounting arm adapter C9900-M763 or on site by customer installation.
The protective cap of the USB socket (X102, X103) must be fully tightened to meet the IP65 rating.
Do not use the USB socket on the back side of the Panel PC unless the area is known to be non-hazardous.
The Ethernet sockets (X104, X105) must be closed with the connector of the connection cables
(Accessories) or by the protection cover mounted with the nylon cord to meet the IP65 rating.
The cover plate of the CFast card and the battery must be tightened with a torque of 0.5 - 0.6 Nm.
The equipment shall be installed in such a way that the risk of mechanical danger is low.
The equipment shall only be used in an area of not more than pollution degree 2, as defined in IEC 60664-1.
The Panel PC may only be mounted horizontally (see: Mounting).
