Introduction - Honeywell Class 320 Meter Installation Instructions Manual

1.0 INTRODUCTION

The Honeywell Class 320 meter is a 3-element meter with communications. The
device is used to monitor electric power usage of individual loads after the utility meter
and store kW and kVAR data for automatic meter reading. Installation must only be
performed by qualified personnel and in accordance with these instructions and all
applicable local and national electrical codes. E-Mon and its representatives assume

is suitable for the intended electrical service. For example, Class 320 meters labeled
for 120/208V service MUST NOT be installed on service feeds of 277/480 volts or 347/
600 and vice versa.
