94 Cable Routing In Buildings; 95 Cable Routing Outside Buildings; 96 Installing Network/Bus Cables Between Buildings; 961 Causes Of Surge Voltages - IFM Electronic Ecomat 300 AL1030 Device Manual

IO-Link Master EtherCat
► Install network/bus cables at least 10 cm away from power lines
9.4 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 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
