Sources of interference – Signal cables and power supply lines should not be installed in parallel. If necessary,
metal isolating sments should be placed between the power supply lines and signal
cables.
– Only use connectors with metal housing and connect as much of the shielding as
possible to the housing.
– For outdoor cables between buildings, make sure that grounding is carried out in
accordance with on page 27.
– During installation, all connector locking mechanisms (screws, union nuts) must be
firmly tightened in order to ensure the best possible contact between shielding and
ground. Before initial startup, the ground or shielding connection of cables must be
checked for low-resistance continuity.
– Install network/bus cables in separate cable ducts or separate cable bundles.
– Where possible, do not install network/bus cables parallel to power supply lines.
– Install network/bus cables at least 10 cm away from power lines.
Cable routing in buildings – Where possible, use metal cable hangers.
– Do not install network/bus cables together with or parallel to power supply lines.
– Separate network/bus cables on cable bridges or in cable ducts from power supply
lines using isolating sments.
– Install network/bus cables as far away as possible from sources of interference, such
as motors and welding equipment.
– For long cable connections, install an additional equipotential bonding line between the
terminal points.
Cable routing
outside buildings
– Install network/bus cables in metal pipes that are grounded on both sides or in concrete
cable ducts with continuous reinforcement.
– For long cable connections, install an additional equipotential bonding line between the
terminal points.
