5.2 Electrical connections
Note
Electromagnetic compatibility (EMC)
You can use this device in industrial environments and small businesses. Metal housings show
increased electromagnetic compatibility compared to high-frequency radiation. The protection
from high-frequency radiation can be increased by grounding the housing.
Note
Improvement of interference immunity
• Lay signal cables separately from cables with voltages > 60 V.
• Use cables with twisted wires.
• Install the device and lay its cables at a distance to strong electromagnetic fields.
• Use shielded lines to guarantee the full specification according to Ethernet/PROFIBUS.
Note
Unstable plug-in connections
Plug-in connections without interlock can loosen and fall out. Operation with Ex py or Ex ec can
cause an ignition.
• Secure plug-in connections without interlock mechanically, for example, with a cable tie.
