3. Introduction

The present operating manual contains specifications, installation instructions and troubleshooting
procedures for ACM  D2/S2 inverters.

The information in this manual must be known before installation of the inverter in order to
guarantee fault-free installation and thus maximum performance.

The information contained in this manual refers to the software versions D2A-STD-020A and
D2A-1300-021.
