MAIN INFORMATION
1.1)
INTRODUCTION
EMA11 was engineered and tested in compliance with IEC 348 class 1 standards for operating
voltages up to 600 Vac rms, considering the VDE 0110 group C isolation standards for operating
voltages up to 500 Vac rms.
The present manual contains all of the information warnings that must be followed up by the operator
to ensure a right use of the equipment and to maintain the safe operating conditions.

DESCRIPTION
The EMA11 is an instrument which has been designed to monitor, store and analyze all electrical
variable in a distribution line.
All the relevant data are displayed and, if desired, stored on internal RAM and transmitted to a remote
PC, via RS485 (standard) on which the compatible management software has been installed.
It is possible to monitor via digital outputs (2 dig. out. standard) alarms, sirens or strategically factory
loads.
EMA11 with optional harmonic analyzes can carry out network harmonic content analyzes with FFT
st
method up to the 31 harmonic, very useful to locate network disturbances.
The EMA can perform accurate deep and complete energy analyzes.
A fundamental feature of EMA11 is the easy way to integrate new additional options and the
upgrading of the firmware using serial port and flash technology.
All parameters are displayed on a graphic LCD display light-back with a resolution of 128x128 dots.
Displaying and programming mode are carried out by means of a 5 buttons keyboard.
