Conformity to Low Voltage Directive in EU
[Available only for the products with CE or TÜV mark]
CAUTION
1. Safe separation for control
interface of this inverter is provided
when this inverter is installed 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 installed in overvoltage
category III. An isolation transformer has
to be installed between power supply
mains and this inverter when SELV
circuit from
connected to this inverter directly.
Otherwise supplementary insulation
between control interface of this inverter
and environment must be provided.
3. The ground terminal
be connected to the ground. Don't use
only RCD as the sole method of electric
shock protection.
Dimensions of external PE conductor
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 another protective measure
shall be applied such as separation of
the EE from the environment by double
or reinforced insulation or isolation of EE
and supply system by the transformer.
6. The inverter has to be installed in
environment of pollution degree 2. If the
environment is pollution degree 3 or 4,
the inverter has to be installed in a
cabinet of IP54 or higher.
7. Use a cable according to EN60204
Appendix C.

8. Install the inverter, AC or DC reactor,
input or output filter in an enclosure , to
prevent a human body from touching
directly this equipment.
1) When a person can touch each
connecting terminal or live parts,
install the inverter, AC or DC reactor,
input filter in an enclosure with
minimum degree of protection of
IP4X.
2) When a person can not easily touch a
connecting terminal or live parts,
install the inverter, AC or DC reactor,
input filter in an enclosure with a
is minimum degree of protection of
IP2X.
9. It is necessary to install the inverter in
appropriate
appropriate RFI filter to conform to the
EMC
responsibility to check whether the
equipment ,the inverter is installed in,
conforms to EMC directive.
10. Do not
grounding terminal directly. Use crimp
terminal with tin or equivalent plating to
reduce electrochemical potential.
11. Do not remove the keypad panel before
disconnecting
insert/remove the extension cable for
keypad panel remote operation while
power is on. Confirm that the extension
cable is securely latched to keypad
panel and inverter before power is on.
A supplementary isolation is required for
the extension cable when the inverter is
installed in overvoltage category III.
12. Basic insulation for control interface of
this inverter is provided when the
inverter is used at altitude over 2000m.
The use at altitude over 3000m is not
permitted.
13. The supply mains neutral has to be
earthed for VXSM400-3/550-3.
