1. INSTALLATION
Before installation:
•Read the user manual carefully, determine the correct connection diagram.
•Remove all connectors and mounting brackets from the unit, then pass the unit through
the mounting opening.
•Put mounting brackets and tighten. Do not tighten too much, this can brake the
enclosure.
•Make electrical connections with plugs removed from sockets, then place plugs to their
sockets.
•Note that the power supply terminal is separated from measurement terminals.
Below conditions may damage the device:
•Incorrect connections.
•Incorrect power supply voltage.
•Voltage at measuring terminals beyond specified range.
•Current at measuring terminals beyond specified range.
•Connecting or removing data terminals when the unit is powered-up.
•Overload or short circuit at relay outputs
•Voltage applied to digital inputs over specified range.
•High voltage applied to communication port.
Current Transformers must be used for current
measurement.
No direct connection allowed.
Below conditions may cause abnormal operation:
•Power supply voltage below minimum acceptable level.
•Power supply frequency out of specified limits
•Phase order of voltage inputs not correct.
•Current transformers not matching related phases.
•Current transformer polarity incorrect.

1.3 ELECTRICAL INSTALLATION
Do not install the unit close to high electromagnetic noise
emitting devices like contactors, high current busbars,
switchmode power supplies and the like.
Although the unit is protected against electromagnetic disturbance, excessive disturbance
can affect the operation, measurement precision and data communication quality.
•ALWAYS remove plug connectors when inserting wires with a screwdriver.
•Fuses must be connected to the power supply and phase voltage inputs, in close
proximity of the unit.
•Fuses must be of fast type (FF) with a maximum rating of 6A.
•Use cables of appropriate temperature range.
•Use adequate cable section, at least 0.75mm
2
(AWG18).
•For current transformer inputs, use at least 1.5mm
2
section (AWG15) cable.
•The current transformer cable length should not exceed 1.5 meters. If longer
cable is used, increase the cable section proportionally.
•Follow national rules for electrical installation.
•Current transformers must have 5A output.
Current Transformers must be used for current
measurement.
No direct connection allowed.

3. DISPLAY NAVIGATION
The button will select the display context and buttons will navigate between
possible values of this context.
Phase indication leds will reflect the phase displayed on the screen.
Phase status leds will turn-on if the related phase voltage is above 70 volts.
Relay led will turn-on when the relay output is active.
Kilo leds will turn on if the displayed value is in kA/kV/kW/kVA/kVAr.
Sigma led will turn on when displaying total values.
V / Hz leds will turn-on when the displayed value is in volts or hertz.
Display of currents: If the CT ratio is below 200/5 then currents will be displayed with
0.1A precision. If the CT ratio is between 200/5 and 2000/5 then currents are displayed
with 1A precision. If the CT ratio is above 2000/5 then currents are displayed with 0.01 kA
precision and the “k” led will turn on.
Display of voltages: If the VT ratio is above 100.0/1 then voltages will be displayed with
0.1kV precision. If the VT ratio is between 100.0/1 and 20.0/1 then voltages will be
displayed with 0.01kV precision. In both cases the “k” led will turn on. If the VT ratio is
below 20.0/1 then voltages are directly displayed with 1V precision.
Display of kW, kVA, kVAr: If the product CTxVT is below 1000 then the values will be
displayed with 0.1k precision. Otherwise they will be displayed with 1k precision.
Display of kWh, kVArh, Hours: Values are displayed with a precision of 0.1 k (or hour).
