Installing signal/control and power cables
General notes
CAUTION
Interference emissions! Risk of injury due to malfunction
and uncontrolled movements!
−
Eliminate sources of interference in the area of the
signal and control cables!
−
Ensure an installation in line with EMC requirements.
The achievable service life of the cables is to a great extent determined by the
type of installation and environmental influences at the place of use. Due to the
large variety of application conditions, the listed basic recommendations for
the handling of cables can, however, only serve as an aid to ensure a long and
fault-free operation of the cables.
●
Lay cables and lines so that they cannot be damaged and no one can trip
over them.
●
Never subject cables to pulling stress or torsion. Mechanically fix the cable
ends in place after no more than approx. 30 cm (e.g. cable clip, cable
binder, etc.)
●
Do not kink cables. Do not fall below the bending radii. The value of the
bending radius should be at least 5-6 times the diameter of the cable.
●
Do not subject cables to large temperature differences and extreme weather
influences. Always store cables in a dry place.
●
Always unroll cables completely.
●
Never use damaged cables (e.g. by pressure, clamping or crushing). In case
of damage, shut the system down and replace the cables.
●
Check the connection cables at regular intervals for damage and exchange
them, if necessary.
●
Check the connections for the protective earthing conductor at regular inter-
vals for proper condition and tight seat.
●
Do not use any silicone-containing sealants, adhesives or insulating agents.
●
Ensure a maintenance-friendly installation, i.e. simple access to the connec-
tion lines. Ensure free access to the connection side.
●
Before the installation note down the information on the nameplates. If after
the installation nameplates are not visible or readable any more, this data
will be available to you at any time.
Cable routing
●
Install signal and control lines with a minimum clearance of 200 mm or using
a grounded partition plate to separate them from the power cables. The
installation in separate cable ducts is the optimum. Whenever possible,
introduce signal lines only at one place into the control cabinet in which the
drive controller is installed ideally not in the direct vicinity.
●
Renew cable markings and warning notes on cable connections which have
become illegible or were lost.
