13-1 General
In accordance with the provisions described in
the European Commission Guidelines Docu-
ment on Council Directive 89/336/EEC,
Fuji Electric Co., Ltd. has chosen to classif
y
the
FVR-C11S ran
g
e of Inverters as "Complex
Components".
Classification as a "Complex Components" al-
lows a product to be treated as an "apparatus",
and thus permits compliance with the essential
requirements of the EMC Directive to be demon-
strated to both an inte
g
rator of FVR Inverters
and to his customer or the installer and the user.
FVR Inverters is supplied ‘CE-marked’, si
g
nif
y
-
in
g
compliance with EC Directive 89/336/EEC
when fitted with specified filter units installed
and earthed in accordance with this sheet.
This Specification requires the followin
g
per-
formance criteria to be met.
EMC product standard EN61800-3/1996

, it is customer’s responsibilit

to
check whether the equipment conforms to
EMC directive.
13-2 RFI Filters
It is stron
g
l
y
recommended that the appropriate
FVR input filter is used, as shown in the follow-
in
g
s, to limit RF current flowin
g
into the main
suppl
y
circuit.
Without an input filter a FVR installation ma
y
not
meet statutor
y
requirement. FVR Inverters con-
tain hi
g
h-power semi-conductor devices which
are switched at hi
g
h speeds to s
y
nthesize a
near-sinusoidal current wave form across the
frequenc
y
ran
g
e of output.
Rapidl

volta

es and currents will

enerate some de

ree of electroma
g
netic emis-
sion. Emissions will be predominantl
y
conducted
throu
g
h the motor and the mains suppl
y
cables,
althou
g
h some radiated emissions will be detect-
ed in close proximit
y
to the drive s
y
stem.
It is essential that precautions are taken both at
the desi
g
n sta
g
e and at the time of installation to
prevent radio frequenc
y
interference (RFI) from
the drive s
y
stem affectin
g
sensitive equipment in
close proximit
y
.
The RFI filters ran
g
e are desi
g
ned especiall
y
for
the FVR Inverter and help to ensure EMC com-
pliance of machiner
y
and installations usin
g
the
Inverters.
The Inverters ma
y
be mounted on top of the filter
usin

the inte
g
ral fixin
g
positions, the intention
bein
g
that valuable space inside wirin
g
cabinets
ma
y
be saved. (Refer to Table 13-2-1)
