Introduction

Thank you for purchasing the Hitachi SJ700-2 Series Inverter.

This Instruction Manual describes how to handle and maintain the Hitachi SJ700 Series Inverter. Read this Instruction Manual carefully before using the inverter, and then keep it handy for those who operate, maintain, and inspect the inverter.

Before and during the installation, operation, inspection, and maintenance of the inverter, always refer to this Instruction Manual to obtain the necessary related knowledge, and ensure you understand and follow all safety information, precautions, and operating and handling instructions for the correct use of the inverter.

Always use the inverter strictly within the range of the specifications described in this Instruction Manual and correctly implement maintenance and inspections to prevent faults occurring.

When using the inverter together with optional products, also read the manuals for those products. Note that this Instruction Manual and the manual for each optional product to be used should be delivered to the end user of the inverter.
