2.2.3 Requirements for use in potentially explosive environments
General safety guidelines
Automation PC 810 devices are suitable for use in the environments described above as well as in environments
that are not at risk of explosion. Wiring must follow national regulations and meet all legal requirements. The devices
must be installed in suitable protective housings and final assembly must be inspected and approved by the local
authorities. Additional equipment must be suitable for the operating location.
Devices with explosion protection are to be used as intended and are only permitted to be operated by knowl-
edgeable and qualified personnel according to these operating instructions and the corresponding user's manual.
Operation in any other way endangers the safety and functionality of the devices and the connected systems. The
operator is responsible for following the applicable safety and accident prevention regulations, as well as adhering
to standards.
Mounting and installation
Automation PC 810 systems must be installed according to the guidelines in the user's manual. In order to guar-
antee sufficient air circulation, the specified amount of space around the device must be observed. The maximum
ambient temperature is 50ºC. A fan kit must be used in conjunction with a 5PC800.BM45-xxx processor board. The
tightening torque for the power supply terminals is 0.5 Nm. Cables must be able to handle a surface temperature of
75°C. Devices must remain voltage free until installation work is complete. Devices must be used within a potential
equalization system and connected to the potential offset. ATEX: Devices must be installed in a protective housing
that meets minimum IP54 (EN 60529) and "tc" (EN 60079-31) protection requirements.
Maintenance
Accumulated dust must be removed regularly.
Breakdowns and disassembly
Devices must be shut down and protected against being accidentally started. Defective devices must be exchanged
by knowledgeable and qualified personnel.
The battery (Renata CR2477N) or fuses must not be removed while voltage is applied or only removed when in
non-hazardous areas.
Danger!
Explosion hazard - Replacing components may impair suitability for Class I, Division 2!
Explosion hazard - Plugs must not be disconnected while voltage is applied or only disconnected when
in non-hazardous areas.
