Table 2-3-4 Selection of peripheral devices
*1 The applicable frame and series of the model of
the molded case circuit breaker (MCCB) and
earth leakage breaker (ELCB) vary according to
the capacity of the transformer of the equipment.
For details of selection, refer to the relevant
technical documents.
*2 The recommended cable size for the main circuit
is PVC cable at ambient temperature 40 degree
C specified in Appendix C of EN 60204
*3 The power supply impedance without a reactor
is considered to be the equivalent of 0.1% of the
inverter capacity, with 10% current unbalance
accompanied by the voltage unbalance.
*4 Use crimp terminals with an insulating cover.
