Quick Installation Guide
❹Voltage Input Connections
Connect phases and neutral references to the
Ⓗ
terminal block, using the order described below:
Terminal Description Signal to be Connected
4 – N
Neutral
3 – Va
Phase ‘R’
2 – Vb
Phase ‘S’
1 – Vc
Phase ‘T’
Measurement Range: 20 to 500Vac Ph-Ph
11,54 to 288,67 Vac Ph-N
❺ Current Input Connections
Connect phase references to the
Ⓘ
terminal
block, using the order described below:
Terminal Description Signal to be Connected
10 – °Ia
CT’s S1 - Phase ‘R’
9 – Ia
CT’s S2 - Phase ‘R’
8 – °Ib
CT’s S1 - Phase ‘S’
7 – Ib
CT’s S2 - Phase ‘S’
6 – °Ic
CT’s S1 - Phase ‘T’
5 – Ic
CT’s S2 - Phase ‘T’
Measurement Range: 20mA to 5Aac
(Continuous Overload: up to 7.5Aac)
❻Accessing Operation Modes
Instantaneous Measurements:
checking
of
V, A, W, VAr, VA, PF
and
Hz
values. To
access this mode, hold the
and
keys simultaneously for three
seconds.
Energy Measurements:
checking of
kWh+, kWh-, kVArh+, kVArh-, kW
and
kVA
values.
To access this mode, hold
the
and
keys simultaneously
for three seconds.
Function (Configurations):
configuration
of constants for PT and CT, connection
diagrams, integration time (demand),
communication parameters and reset
command (energies and demands). To
access this mode, hold the
and
keys simultaneously for three seconds.
❼ Configuring the Product
The first step is to access Function
mode, by holding the
and
keys
simultaneously until the message
Fun
appears in L1. Then, to navigate
through menus use
or
keys
.
To enter a specific menu, use
key.
PT Configuration:
Definition of
Potential Transformer ratio.
Example: 440/220V, PT= 0002.00.
Use
key
to navigate
through
the
digits and
,
to increment or
decrement the value of the active
digit. If no PT is used, PT ratio must
be 0001.00
CT Configuration:
Definition of
Current Transformer ratio.
Example: 500/5A, CT = 0100.00.
Use
key
to navigate
through
the
digits and
,
to increment or
decrement the value of the active
digit. If no CT is used, CT ratio must
be 0001.00
CD Configuration:
Definition of
Connection Diagram, according to
the circuit measured.
Use
key
to navigate
through
the
digits and
,
to increment or
decrement the value of the active
digit. Please refer to the “Connection
Diagrams” table for checking the available CD options.
To confirm a configured value, press till all digits stop
flashing, only the LEDs ‘k’ and ‘M’ will be blinking in this
situation.
