*1 Use this inverter at the following IT system.
Non-earthed (isolated from earth) IT
system
Can be used.
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.).
IT system which earthed neutral
by an impedance
Corner earthed / Phase-earthed IT
system by an impedance
Cannot be used
