Warning
All PE cables must be connected before commissioning for reasons of safety.
The mains PE connection is connected to the central PE connection point of the
SEC−ST.
Make sure that the earth connections between devices and the mounting plate
are of sufficiently large dimensions in order to be able to discharge HF interfer
ence.
Electrical isolation
In the design of the MTRE−ST, great importance has been placed on high resistance
to interference. For this reason individual function blocks are electrically isolated
from each other. Signal transmission within the MTRE−ST is carried out by an opto
coupler.
Measures for complying with EMC guidelines
If correctly fitted and if Festo cables are used for all the connections, motors
MTRE−ST−... will comply with the regulations specified in the technical standards
EN 50081−2 (interference emission) and EN 61000−6−2 (resistance to interference).
Interference emission and resistance to interference of a device always depend on
the complete design of the drive, which consists of the following components:
the power supply
the motor
the electromechanics
the design and type of wiring
higher−order controller.
Make sure that all individual components comply with the EMC guidelines.
S
Only use original parts of Festo.
