Simplified User Guide

 This document is intended as a quick user guide for the
i 20 Indicator.
It allows a quick start of the device. For electrical connection
and installation, refer to the following manuals :
• Wiring block diagram : 04-50-00 DD

• User manual : 04-50-00 MU

Safety

Standard NF EN 60 950 requires that instruments are

connected via a power outlet and that the outlet is in close
proximity to the instrument. An easily accessible isolator
device must be installed when the instrument is permanently
connected to the mains.
