S.1 Introduction
Thank you for purchasing Hitachi WJ Series C1 Inverter. (Afterward "Hitachi WJ Series C1 Inverter"
referred to as WJ-C1.)
This is a User's Guide that describes the handling and maintenance of the WJ-C1.
For the purpose of paper consumption reduction and provision of the latest information, we
enclose the WJ-C1 Basic Guide only, while providing the WJ-C1 User's Guide (this Guide) for more
detailed description through electronic means instead of CD or a printed document.
About the Basic Guide (Bundled with product)
 The WJ-C1 Basic Guide provides the minimum information necessary for handling the product. Be sure
to read this document as well as the WJ-C1 User's Guide for more detailed information.
About the User's Guide (This document)
 The WJ-C1 User's Guide provides detailed information necessary for handling the product. Be sure to
read the User's Guide for proper use.
If there are any differences between the WJ-C1 Basic Guide and the WJ-C1 User's Guide due to
updates, etc., the contents on the Guide with the latest version will have higher priority. The version of
the Guide is shown in underlined alphabet like the following example, and the alphabet changes to A,
B, C... by the revision. For example, comparing the User's Guide NT361AX and the Basic Guide
NT3611BX, the Basic Guide contains the latest contents. Always use the WJ-C1 inverter strictly within
the range described in the latest contents on the Guide and perform proper inspection and
maintenance to prevent failures or accidents.
