Note 1）The peripheral equipment described here is applicable when the inverter connects a standard Hitachi 3-phase,

4-pole squirrel-cage motor.

Note 2）Select breakers that have proper capacity. (Use breakers that comply with inverters.) Select above proper ELB

capacity following above table for the 1pc inverter.1pc inveter must be supplied by the above proper 1pc ELB.

Note 3）If the power line exceeds 20m, cable that is thicker than the specified applicable cable must be used for the

power line.

Note 4）Use copper electric wire (HIV cable) of which the maximum allowable temperature of the insulation is 75°C.

Note 5）Use earth-leakage breakers (ELB) to ensure safety.

Note 6）To comply UL, use either ELB/or FUSE which is specified by UL for the Power supply for the inverter.

(

Please refer to Chapter1 “1.3 Precautions Concerning Compliance with UL and cUL Standards”)

Note 7）The earthed line, please use things more than electric wire diameter to show to the power line.
