General precautions
Connection for interference free operation:
• The EMC approval requires that signal connections are made with shielded cables and metal
connectors only.
• To ensure optimal electrical shielding, all plugged connections are to be screwed or locked into
position.
• Signal cables may not be laid in the same cable trays as power cables.
• Before commissioning the system, check all cable connections.
• Ensure that the permissible values for voltages and signals are upheld.
Safe discharge of electrical disturbances:
• Connect the Panel PC and cabinet by the shortest possible route to a central earth.
• Ensure good electrical connection between Panel PC and cabinet (low-impedance).
• Use an earth connection conductor of minimum 2.5 mm² (0.1 in
2
) diameter.
Special precautions for 230 VAC devices:
• Connect the Panel PC to a socket with a ground contact.
• To disconnect the Panel PC from the power supply, pull out the plug.
• Where a building power socket is used, check that it is easily accessible and as near as possible
to the Panel PC.
• For cabinet mounting, a central circuit-breaker must be provided.
• The plug on the power cord is classified as a circuit-breaker as per EN 60950.
• Pull out the plug before opening the device.
Special precautions for 24 VDC devices:
• The panel PC may be connected to a safety extra low voltage (SELV) circuit only.
• The circuit transformer must fulfil the pertinent standards.
