200V type inverters can be used at IT or TT system.
Use 400V type inverters at the following IT or TT system.
*1) EMC filter : on
Earthed condition
Non-earthed (isolated from earth) IT system
IT system which earthed neutral by an impedance
Corner earthed / Phase-earthed system by an
impedance or earthed system of 400V(TT system)
*2) EMC filter : off
Earthed condition
Non-earthed (isolated from
earth) IT system
IT system which earthed
neutral by an impedance
Corner earthed /
Phase-earthed system by an
impedance or earthed
system of 400V(TT system)
*1,2)According to chapter 11.1.2.3 of User's manual, turn the EMC filter off.
*3)"product ver." descripted in note Colum, means the alphabet symbol of SER.NO.'s end.
Use 575V type inverters at the following IT or TT system.

In this case the insulation between the control interface and the main circuit of
the inverter is basic insulation. Thus do not connect SELV circuit from
external controller directly (make connection using a supplementary
insulation.)
Use an earth fault detector able to disconnect the power within 5 s after the
earth fault occurs.
