Chapter 1 - Introduction - Hitachi SJ300 Series Replacement Manual

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. Since the SJ300 is different from the J300 in dimension, you need to make additional mounting holes
or prepare an attachment plate when replacing. Please refer to the Chapter 2 – Installation.
2. If the parameter settings for the J300 you use defer from the default parameter setting for the SJ300,
you need to change the parameters as you desire.
Please refer to the Chapter 4 – Parameter Setting.
