Quick Reference Guide

Caution: Be sure to read the SJ2002Inverter Manual and follow

its Cautions and Warnings for the initial product installation.

This Quick Reference Guide is intended for reference use by

experienced users in servicing existing installations.

UL®Cautions, Warnings, and Instructions

Wiring Warnings for Electrical Practices and Wire Sizes

The Cautions, Warnings, and instructions in this section summarize the

procedures necessary to ensure an inverter installation complies with

Underwriters Laboratories®guidelines.

Warning: “Use 60/75°C Cu wire only” or equivalent.

Warning: “Open Type Equipment.”

Warning: “Suitable for use on a circuit capable of delivering

not more than 100,000 rms symmetrical amperes, 240 V

maximum.” For models with suffix N or L.

Warning: “Suitable for use on a circuit capable of delivering

not more than 100,000 rms symmetrical amperes, 480 V

maximum.” For models with suffix H.

Warning: “Hot surface—risk of burn.”

Warning: “Install device in pollution degree 2 environment.”

Warning: “Maximum Surrounding Air Temperature 50°C.”

Warning: “Risk of electric shock—capacitor discharge time is at

least 5 minutes.”

Warning: “Solid state motor overload protection is provided in

each model.”

Warning: “Tightening torque and wire range for field wiring

terminals are marked adjacent to the terminal or on the wiring

diagram.”

Terminal Tightening Torque and Wire Size

The wire size range and tightening torque for field wiring terminals are

presented in the tables below.

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 SJ2002inverters 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 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.
