Conformity to the Low Voltage Directive in the EU (Continued)
10. The inverter has been tested with IEC/EN 61800-5-1 2007 Short-circuit Test under the following
conditions.
Short-circuit current in the supply: 10,000 A
240V or below (200V class series inverters of 18.5 kW (25HP) or below.)
230V or below (230V class series inverters of 22 kW (30HP) or above.)
480V or below (480V class series inverters)
11. Use this inverter at the following power supply system.
*1 Use this inverter at the following IT system.
Non-earthed (isolated from earth) IT
system
IT system which earthed neutral
by an impedance
Corner earthed / Phase-earthed IT
system by an impedance
*2 Cannot apply to Corner earthed / Phase-earthed TT system of 400V type.

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.).
Use an earth fault detector able to disconnect the power
within 5s after the earth fault occurs.
Can not be used
