FVR-C11S-EN
Compliance with low volta
g
e directive in
EU [Applicable to products with T
Ü
V
mark]
CAUTION
1. Safe separation for control interface of this
inverter is provided when this inverter is in-
stalled in overvolta
g
e cate
g
or
y
II. PELV
(Protective Extra Low Volta
g
e) circuit or
SELV (Safet
y
Extra Low Volta
g
e) circuit
from external controller is connected to the
interface directl
y
.
2. Basic insulation for control interface of this
inverter is provided when this inverter is in-
stalled in overvolta
g
e cate
g
or
y
III. An insu-
lation transformer has to be installed
between power suppl
y
mains and this in-
verter when SELV circuit from external
controller is connected to this inverter di-
rectl
y
. Otherwise supplementar
y
insulation
between control interface of this inverter
and environment must be provided.
3. The
g
round terminal G should alwa
y
s be
connected to the
g
round. Don’t use onl
y
RCD as the sole method of electric shock
protection. Dimensions of external PE con-
ductor should be same as dimensions of
input phase conductor and capable for
possible fault.
4. Use MCCB or MC that conforms to EN or
IEC standard.
5. Where RCD (Residual-current-operated
protective device) is used for protection in
case of direct or indirect contact, onl
y
RCD
of t
y
pe B is allowed on the suppl
y
side of
this EE (Electric equipment). Otherwise an-
other protective measure shall be applied
such as separation of the EE from the en-
vironment b
y
double or reinforced insula-
tion or isolation of EE and suppl
y
s
y
stem
b
y
the transformer.
6. The inverter has to be installed in environ-
ment of pollution de
g
ree 2. If the environ-
ment is pollution de
g
ree 3 or 4, the
inverter has to be installed in a cabinet of
IP54 or hi
g
her.
7. Use a prescribed wire accordin
g
to the
EN60204 Appendix C.
8. Install the inverter, AC or DC reactor, out-
put filter in an enclosure that meets the
followin
g
requirement, to prevent a hu-
man bod
y
from touchin
g
directl
y
to these
equipment.
1) When a person can touch easil
y
on each
connectin
g
terminal or live parts, install
the inverter, AC or DC reactor, output fil-
ter in an enclosure with minimum de-
g
ree of protection of IP4X.
2) When a person can not touch easil
y
on
each connectin
g
terminal or live parts,
install the inverter, AC or DC reactor,
output filter in an enclosure with a mini-
mum de
g
ree of protection of IP2X.
9. It is necessar
y
to install the inverter in ap-
propriate method usin
g
an appropriate
RFI filter to conform to the EMC directive.
It is customer’s responsibilit
y
to check
whether the equipment, the inverter is in-
stalled in, conforms to EMC directive.
