5.1 Installation according to EMC (installation of a CE−typical drive system)
ƒ The electromagnetic compatibility of the ETC Motion Control depends
on the type and diligence of the installation. Pay particular attention
to:
– Layout
– Shielding
– Earthing
ƒ If the installation differs, the system must be checked for compliance
with the EMC limits in order to evaluate the conformity with the EMC
directive. This applies e.g. to the use of unshielded cables
ƒ The responsibility for complying with the EMC directive is with the end
user.
ƒ If you observe the following measures, you can assume that no EMC
problems will arise and the EMC directive or EMC legislation will be
complied with.
ƒ If devices are operated near the system which do not meet the CE
requirements for noise immunity in EN 61000−4−2, these devices could
be electromagnetically interfered with by the ETC ETC Motion Control
System.
ƒ Make contact between top hat rail and earthed mounting plate:
– Mounting plates with electrically conducting surfaces (zinc plated or
stainless steel) permit a continuous contact.
– Painted plates are not suitable for EMC compliant installation.
ƒ If you use several mounting plates:
– Connect mounting plates to each other over a large surface (e.g.
using copper strips).
ƒ When laying cables ensure the physical separation of signal and
network cables.
ƒ Lay the cables as close as possible to the reference potential. Freely
suspended cables act like aerials.
