Safety Instructions

FVR-C11S-EN
Compliance with low voltage directive in
EU [Applicable to products with TÜV
mark]
CAUTION
1. Safe separation for control interface of this
inverter is provided when this inverter is in-
stalled in overvoltage category II. PELV
(Protective Extra Low Voltage) circuit or
SELV (Safety Extra Low Voltage) circuit
from external controller is connected to the
interface directly.
2. Basic insulation for control interface of this
inverter is provided when this inverter is in-
stalled in overvoltage category III. An insu-
lation transformer has to be installed
between power supply mains and this in-
verter when SELV circuit from external
controller is connected to this inverter di-
rectly. Otherwise supplementary insulation
between control interface of this inverter
and environment must be provided.
3. The ground terminal
G should always be
connected to the ground. Don’t use only
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, only
RCD
of type B
is allowed on the supply side of
this EE (Electric equipment). Otherwise an-
other protective measure shall be applied
such as separation of the EE from the en-
vironment by double or reinforced insula-
tion or isolation of EE and supply system
by the transformer.
6. The inverter has to be installed in environ-
ment of pollution degree 2. If the environ-
ment is pollution degree 3 or 4, the
inverter has to be installed in a cabinet of
IP54 or higher.
7. Use a prescribed wire according to the
EN60204 Appendix C.
8. Install the inverter, AC or DC reactor, out-
put filter in an enclosure that meets the
following requirement, to prevent a hu-
man body from touching directly to these
equipment.
1) When a person can touch easily on each
connecting terminal or live parts, install
the inverter, AC or DC reactor, output fil-
ter in an enclosure with minimum de-
gree of protection of IP4X.
2) When a person can not touch easily on
each connecting terminal or live parts,
install the inverter, AC or DC reactor,
output filter in an enclosure with a mini-
mum degree of protection of IP2X.
9. It is necessary to install the inverter in ap-
propriate method using an appropriate
RFI filter to conform to the EMC directive.
It is customer’s responsibility to check
whether the equipment, the inverter is in-
stalled in, conforms to EMC directive.
