Interference – Signal and power supply cables should not be installed in parallel. If necessary, metal<br />
isolating segments should be placed between the power supply and signal cables.<br />
– During installation, all connector interlocks must be firmly tightened to ensure the best<br />
possible contact.<br />

– Install AS-i cables in separate cable ducts.<br />
– Install AS-i cables with a minimum distance of 10 cm to power cables.<br />
Cable routing in buildings – Where possible, use metal cable hangers.<br />
– Install AS-i cables as far away as possible from sources of interference, for example,<br />
motors and welding equipment.<br />
6.1 Interference Suppression Measures<br />
Phoenix Contact re<strong>com</strong>mends connecting relay coils or motor coils with an RC element to<br />
protect the devices against interference. Depending on the application, the delay time of the<br />
relay can be increased by approximately 1 ms.<br />

Relay coil with RC element<br />
For the sizing of the RC element the following values are re<strong>com</strong>mended:<br />
R = 100 Ω to 200 Ω; C=220nFto470nF.<br />
