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 segments�
►
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�
9.5 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�
9.6 Installing network/bus cables between buildings
9.6.1 Causes of surge voltages
Surge voltages occur as a result of switching operations, electrostatic discharge,
and lightning discharge� Surge voltages can be inductively, capacitively or
galvanically coupled into electrical cables for mains supply, measured value
transmission, and data transmission� In this way, surge voltages reach the power
supply units and the interfaces of systems and devices�
9.6.2 Equipotential bonding line
Install an additional equipotential bonding line between the grounding points of
buildings, preferably in the form of
– a metal-reinforced concrete channel,
– an additional grounding cable or
– a metal pipe�
9.6.3 Surge protective devices
ifm recommends wiring all the wires of the cable to surge protective devices in order to protect the
devices against surge voltages�
Observe all national and international regulations when installing surge protective devices�
