Wire Connectors

Warning: Field wiring connections

must be made by a UL Listed and CSA

Certified ring lug terminal connector

sized for the wire gauge being used.

The connector must be fixed using the

crimping tool specified by the con-

nector manufacturer.

Fuse and Circuit Breaker Sizes

The inverter’s input power wiring must include UL Listed, dual-element,

600V fuses, or UL Listed, inverse-time, 600V circuit breakers.

Motor Overload Protection

Hitachi SJ300 inverters provide solid state motor overload protection,

which depends on the proper setting of the following parameters:

• B012 “electronic overload protection”

• B212 “electronic overload protection, 2nd motor”

• B312 “electronic overload protection, 3rd motor”

Set the rated current [Amperes] of the motor(s) with the above parame-

ters. The setting range is 0.2 * rated current to 1.2 * rated current.

Warning: When two or more motors are connected to the

inverter, they cannot be protected by the electronic overload pro-

tection. Install an external thermal relay on each motor.
