1. Introduction

This manual is designed to ensure the safe and correct operation of the TOSNIC-7000S Uninterruptible Power System (hereafter referred to as "UPS unit"). Please read the "Safety Precautions" and "Operation" sections of this manual carefully before use and make sure you have a thorough understanding of the information in these two sections. Keep the manual handy in a place near the unit so you can refer to it instantly when needed.

Note that this manual was written based on the standard circuits shown in figures 6.2 (page 13). The delivered UPS system may, if desired by the customer, differ from the standard configuration. Similarly, the displayed markings may differ from those on the standard system. If this is the case, follow the operating procedures and indications provided in the development circuit diagrams created individually for the UPS system actually delivered.

Also, while this manual uses the term UPS, the equipment may be marked "CVCF" according to customer specifications. If this is the case, remember that the term UPS in the manual is equivalent to CVCF.
