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 insulation transformer has to be installed between power
supply mains and this inverter when SELV circuit from external controller is connected to this
inverter directly. 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 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 prescribed wire according to the EN60204 Appendix C.
8. Install the inverter, AC or DC reactor, input or output filter in an enclosure that meets the
following requirement, to prevent a human 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 filter in an enclosure with minimum degree 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 minimum degree of
protection of IP2X.
9. It is necessary to install the inverter in appropriate 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 installed in, conforms to EMC directive.
10. Do not connect copper wire to grounding terminal directly. Use cramp terminal with tin or
equivalent plating to reduce electrochemical potential.
11. Do not remove the keypad panel before disconnecting power and do not 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 FVR-E11S-4EN.
