Conformity to the Low Voltage Directive in the EU
If installed according to the guidelines given below, inverters marked with CE are considered as
compliant with the Low Voltage Directive 2006/95/EC.

*1 The frame size and model of the MCCB or RCD/ELCB (with overcurrent protection) will vary, de-
pending on the power transformer capacity. Refer to the related technical documentation for details.
*2 The recommended wire size for main circuits is for the 70
C 600V PVC wires used at an ambient
temperature of 40
C.
*3 In the case of no DC reactor, the wire sizes are determined on the basis of the effective input current
calculated under the condition that the power supply capacity and impedance are 500 kVA and
5%, respectively.
