CE Mark Installation Requirements
The following requirements for surge, electrostatic discharge (ESD), and fast
transient burst (FTB) protection must be met for applications that require CE Mark
listing:
T The VersaMax I/O Station is considered to be open equipment and should
therefore be installed in an enclosure (IP54).
T This equipment is intended for use in typical industrial environments that
utilize anti-static materials such as concrete or wood flooring. If the equipment
is used in an environment that contains static material, such as carpets,
personnel should discharge themselves by touching a safely grounded surface
before accessing the equipment.
T If the AC mains are used to provide power for I/O, these lines should be
suppressed prior to distribution to the I/O so that immunity levels for the I/O
are not exceeded. Suppression for the AC I/O power can be made using
line-rated MOVs that are connected line-to-line, as well as line-to-ground. A
good high-frequency ground connection must be made to the line-to-ground
MOVs.
T AC or DC power sources less than 50V are assumed to be derived locally from
the AC mains. The length of the wires between these power sources and the
PLC should be less than a maximum of approximately 10 meters.
T Installation must be indoors with primary facility surge protection on the
incoming AC power lines.
T In the presence of noise, serial communications could be interrupted.
