9 Installation

When preparing for cable installation, the local conditions and the corresponding
mounting regulations are very important Cables can be installed, for example, in
cable ducts or on cable bridges
Data corruption and loss
A minimum distance between the cabling and possible sources of interference (eg, machines,
welding equipment, power lines) is defined in the applicable regulations and standards During
system planning and installation, these regulations and standards must be taken into account and
observed
Protect the bus cables from sources of electric/magnetic interference and mechanical strain
Observe the following guidelines regarding "electromagnetic compatibility" (EMC) to keep mechanical
risks and interference to a minimum
9.1 Mechanical strain
► Choose the correct cable type for the respective application (eg, indoor or
outdoor installation, drag chains)
► Observe the minimum bending radius
► Make sure that cables do not enter the shear area of moving machine parts
► Do not install bus cables at right angles to driving routes and machine
movements
► Use cable ducts and cable bridges
► Observe the specifications of the cables used
9.2 Sources of interference
Signal cables and power supply lines should not be installed in parallel
► If necessary, metal isolating segments 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 "Installing network/bus cables between buildings"
► 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
9.3 Cable routing in control cabinets
► 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
