Three-phase active power energy meter with serial S-Bus interface, Pic. 1
Description
Energy meter with serial S-Bus interface enables the reading
of all relevant data like consumption, current, voltage and
power (active and reactive).
Indicating elements (Pic. 4)
T1total (kWh)
■
Shows total consumption
T1part. (kWh)
■
Shows partial consumption, this
value is resettable
CT
■
Shows the set current transformer
ratio
Select
■
When the Z1-Z2 bridge is open the
transformer ratio can be selected
under Menu item Select.
P(kW)
■
Shows the instantaneous power
per phase or all phases
U(V)
■
Shows the voltage per phase
I(A)
■
Shows the current per phase
kWh
■
Shows the unit kWh when the
consumption is displayed
L1 / L2 / L3
■
For P-, U-, I- or Error display, the
corresponding phase is displayed
Error
■
In case of missing phase or wrong
current direction. The correspond-
ing phase is additionally displayed.

Notes before connecting
1. Do not connect L1, L2 or L3 to N
2. In order to avoid moisture in the meter due to condensa-
te build-up, acclimatise the meter at room temperature
for about half an hour before connecting.
3. N must always be connected.
Attention!
These devices must only be installed by a professional
electrician, otherwise there is the risk of fire or the risk of
an electric shock.

Installation instructions
The three-phase energy meter can be attached to a 35 mm
rail (EN 60715, TH35).
The meter can be used only in installation cabinets.
Operation of the LCD display
See page with LCD menu navigation.
The bridge Z1-Z2 should be removed for adjusting the
transformer ratio.

Wiring diagram
The secondary, mains current transformer
connection is to be connected to the phase to
be measured and therefore the transformer
don’t have to be grounded.
This connection is to be fused according to the local
installation instructions.
