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.
