Tests required by the
e
European Directives and based on standard IEC/EN 61131-2.
(1)
Devices must be installed and wired in accordance with the instructions in the “Grounding and
Electromagnetic Compatibility of PLC Systems” manual, available in pdf format on the
CD-ROM supplied with Unity Pro or PL7 software packages or included on DVD reference
UNY USE 909 CD M
(
see page 6/20).
(2)
These tests are carried out with no enclosure, with the devices
fixed on a metal grid
and
wired in accordance with the recommendations in the “Grounding and Electromagnetic
Compatibility of PLC Systems” manual.
(3)
In cases where the limits of electromagnetic emissions between 30 MHz and 1 GHz need
to be monitored, it is recommended that
TSX RKY 6EX/8EX
racks be used instead of
TSX RKY 6/8
racks.
(4)
The devices must be installed in a metal enclosure.
