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 connector manufacturer.
Hitachi SJ700 inverters provide solid state motor overload protection, which depends on the
2
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 parameters. The setting range is
0.2 * rated current to 1.2 * rated current.
WARNING: Integral solid state short circuit protection does not provide branch circuit
protection. Branch circuit protection must be provided in accordance with the NEC and any
additional local codes.
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.
