4 Installation / Preparation for commissioning

4.1 Basic rules

● The shielding effect of cables must also be ensured after installation (bending
radii/tensile strength!) and after connector changes. In cases of doubt, use more
flexible cables with a higher current carrying capacity.
● Only use connectors for connecting the measuring system, which ensure good
contact between the cable shield and the connector housing. Connect the cable
shield to the connector housing over a large area.
● A 5-wire cable with a PE-conductor isolated from the N-conductor (so-called TN
network) should be used for the drive/motor cabling. This will largely prevent
equipotential bonding currents and the development of interference.
● Equipotential bonding measures must be provided for the complete processing
chain of the system. In particular compensating currents caused by differences in
potential across the shield to the measuring system must be prevented.
● A shielded and stranded data cable must be used to ensure high electromagnetic
interference stability of the system. The shielding should be connected with low
resistance to protective ground using large shield clips at both ends. The
shielding should be grounded in the switch cabinet only if the machine ground is
heavily contaminated with interference towards the switch cabinet ground.
● Power and signal cables must be laid separately. During installation, observe the
applicable national safety and installation regulations for data and power cables.
● No stub lines.
● Separation respectively differentiation of the measuring system from possible
interfering transmitters.
● Observe the manufacturer's instructions for the installation of converters and for
shielding power cables between frequency converter and motor.
● Ensure adequate dimensioning of the energy supply.
● The applicable standards and guidelines are to be observed to insure safe and
stable operation. In particular, the applicable EMC directive and the shielding and
grounding guidelines must be observed.
● Upon completion of installation, a visual inspection with report should be carried
out.
