INTRODUCTION
These state-of-the-art panel meters are designed foraccurate
measurement of the AC RMS voltage, ACRMS current, frequency, active
power and powerfactor in single-phase systems. The
currenttransformer ratio can be set between 5/5A and5000/5A via
front panel buttons.
Devices have separate inputs for supply andmeasurement.
The unit allows both manual selection of the displaychannel and
automatic scrolling.
Changing Display Selection:
By using the MENU button, voltage, current,active power, power
factor and frequency can beselected and read from display. Every
depression on
the MENU button will display the nextmeasurement.
60 seconds after the last keypress, the display willreturn
automatically to the default display mode.However the defult
display mode is selectable byprogramming.
SETTING THE CURRENTTRANSFROMER RATIO
AND THE DEFAULT DISPLAY
Any measured parameter can be set as the defaultdisplay.
Automatic parameter scrolling is also
provided. Selections are stored into a non-volatilememory and is
not affected from power failures.

PRECAUTIONS FOR INSTALLATIONAND SAFE USE
Failure to follow below instructionswill result in death or
serious injury
Do not open the unit. There is no serviceable partsinside.
Fuses must be connected to the power supply andphase voltage
inputs, in close proximity of the unit.
Fuses must be of fast type (FF) with a maximumrating of 6A.
Disconnect all power before working on equipment.
When the unit is connected to the network do nottouch
terminals.
Short circuit terminals of unused current
transformers.Do not try to clean the device with solvent or
the
like. Only clean with a dry cloth.
Verify correct terminal connections before applyingpower.
Electrical equipment should be serviced only bycompetent service
personnel. No responsibility isassured by the manufacturer or any
of itssubsidiaries for any consequences arising out ofthe use of
this material.
Only for front panel flush mounting.
Before installation

diagram.
Remove all connectors and mounting bracketsfrom the unit, then
pass the unit through themounting opening.
Put mounting brackets and tighten. Do not tightentoo much, this
can brake the enclosure.
Make electrical connections with connectorsremoved from sockets,
then place connectors totheir sockets.
Note that the power supply terminal is separatedfrom measurement
terminals, with common neutralpoint.
