Circuit Breaker and Fuse Sizes
The inverter’s connections to input power must include UL Listed inverse time circuit
breakers with 600V rating, or UL Listed fuses as shown in the table below.
Motor Overload Protection
Hitachi L200 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”
Set the rated current [Amperes] of the motor(s) with the above parameters. 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 protection. Install an external thermal relay on each
motor.
