Laying <strong>PROFINET</strong> cables<br />
1.3.13 Avoiding sharp edges<br />
• Sharp edges may damage the<br />
<strong>PROFINET</strong> cable. You should<br />
there<strong>for</strong>e de-burr sharp edges –<br />
e.g. the cutting edges of cable<br />
ducts – using a de-burring tool or<br />
file.<br />
• Use plastic edge protectors to<br />
protect edges <strong>and</strong> angles.<br />
• Use bends limiting parts in the<br />
direction of cable routing at the end<br />
of the duct or cable channel. That<br />
helps to prevent a kink of the<br />
cables.<br />
1.3.14 Adding supplementary cables<br />
When laying additional cables, make sure that existing <strong>PROFINET</strong> cables <strong>and</strong> other<br />
system cables are not overstrained or damaged. This may happen e.g. in case the<br />
<strong>PROFINET</strong> cables are laid together with other cables on a joint cable tray (as long<br />
as permitted by electric safety). Take special care when installing new cables (<strong>for</strong><br />
repair or upgrades). It is particularly critical to run several cables in one protection<br />
tube. This may cause damage to those cables already laid in the tube.<br />
Lay the <strong>PROFINET</strong> cable lastly when running it with other cables in the same cable<br />
duct.<br />
