The same EMC compatibility rules apply both for indoor and outdoor routing of
cables. The following also applies:
• Running cables on metal cable trays.
• Electrical connection of the joints of cable trays/ducts.
• Ground the cable carriers.
• If necessary, provide adequate equipotential bonding between connected
devices.
• Take the necessary (internal and external) lightning protection and grounding
measures in as far as they are applicable to your particular application.
