Safety instructions

The following safety instructions must be followed during installation and working with networks and the software.

Explosion protection

WARNING

Risk of explosion

Gases or dusts can be ignited in potentially explosive atmospheres. Read and follow the safety instructions to prevent deflagrations or explosions.

The Embedded PC must be installed in a housing, which ensures protection class IP54 for gas according to EN 60079-15. A housing with protection class IP54 is required for non-conductive dust. IP6X is required for conductive dust according to EN 60079-31.

Observe the temperature at the cable entry points into the housing. If the temperature during nominal operation is higher than 70 °C at the entry points or higher than 80 °C at the wire branching points, cables must be selected that are designed for these high temperatures and operation in potentially explosive atmospheres.

Tighten the screws of the fieldbus connectors firmly so that the connectors do not slip out due to vibrations. Only use RJ45 connectors with an intact latching lug.

Maintain the prescribed ambient temperature during operation. The permissible ambient temperature range during operation is 0 °C to +55 °C.

Take measures to prevent the rated operating voltage exceeding 119 V through short-term interference voltages.

Switch off the power supply and ensure that no explosive atmosphere occurs when:
