Interference of network data transmission due to AC cables
When AC cables are in operation, they generate an electromagnetic field which may induce leading or lagging
interference in network cables during data transmission.
• Lay the network cables using suitable fastening material while observing a minimum clearance of 50 mm to
the AC cables.
