  • Page 2: Chapter 1 - Introduction

    Chapter 1 – Introduction This manual describes how to replace the J300 series inverter with the SJ300 series. Please make sure to understand the procedure and the notes in this manual before replacement. Major points that should be understood beforehand are: 1.

  • Page 3: Chapter 2 - Installation

    Chapter 2 – Installation Since the J300 series and the SJ300 series have different dimensions, you need to make additional mounting holes or prepare an attachment plate when replacing. Please refer to the following figures for the dimensional comparison. 2.1 In the case of making additional mounting holes Please check beforehand that the existing wires for the J300 have enough length to be connected to the terminals of the SJ300 because, depending on where the SJ300 is placed, the wires may not reach the terminals.

  • Page 23 The default value and the maximum value for the carrier frequency are different between J300 and SJ300. While the maximum value of the carrier frequency is set as default in the case of the J300, SJ300’s carrier frequency defaults to 5kHz (3kHz: 75kW to 150kW). SJ300’s carrier frequency can be adjustable up to 15kHz (10kHz: 75kW to 150kW) with derating.
