Device Switch-on
•
When the device is switched on, the firmware version and the model appear on the
display for one second. (Preliminary Page)
•
If no button is pushed for 40 seconds, the display goes back to the Main Page and the
backlight is switched off.
•
The first button pushing does not change the page but is used
to switch the backlight on.

OK button: to confirm the modification of a parameter
• In case the cabling sequence is wrong, this
message appears. In this condition, the
Energy Meter continues to measure and to
increase the Energy Registers, but its
calculation is not correct.
• By pushing OK button for 5 seconds, this
message disappears until next restart
• In case the display shows these messages,
the device has got a malfunction and
must be replaced
• When this page is on the display, it is
possible to reset the Partial Energies
(Main Energies are not resettable).

Wiring diagram
• The Energy Meter has OVERVOLTAGE CATEGORY lll (according to IEC 62052-31 that refers to IEC-60664-1 Ed. 2.0:2007), hence its direct connection to the Public Electricity
Grid is not allowed. The Energy Meter is intended for INDOOR installation only (according to EN 50470-1 and IEC 62052-31). The Energy Meter must be installed on a DIN-rail
and inside a cabinet with a protection degree (IP rating) equal to (or better than) IP51. Direct connection of currents inputs to the Energy Meter is NOT ALLOWED: external CTs
insertion with proper insulation level are mandatory.
U289A U289C
U289B
(
①
) The connection of the Neutral Wire to the “N” terminal of the
Power Meter is mandatory.
Its connection to the Load is optional, but, in the case, only 3-phase
measures (Powers and Energies) are meaningful, while measures referred
to L1, L2, and L3 are meaningless.
(
②
) These manual disconnect switches are mandatory for safe installing
operation. Their purpose and location must be easily evident to installation
personnel
(
③
) These fuses are not mandatory, they are recommended to protect the line,
not the device itself. Use 6 A fast (F) or 1 A delayed (T).
(
④
) Earthing of secondary windings of CTs is governed by the laws in force
in the Countries where the device is installed.
Current transformers must not be operated with open terminals since
dangerous high voltages might occur which may result in personal injuries
and property damage; furthermore, in this case the transformers
are exposed to thermal overload.
Alternative wiring diagram, with only 2 external CTs.
To be used only under the following conditions:
• The load is 3 wires (no neutral) and there is no current leakage (l1 - l2 - l3 = 0)
• Only 3-phase measures (∑ Power and Energies) are meaningful.

Please read this important information!
Intended Use / Use for Intended Purpose
The instrument is a digital multifunctional energy meter certified in accordance with MID. Integrated 4-quadrant measurement permits measurement of
energy import and export.
Thanks to MID certification, acquired data (display) can also be used for the purpose of billing energy costs to third parties.
Via integrated communication interfaces, the values are also forwarded to superordinate management systems. Protection against tampering is provided through
adequate measures (tamper-proof cover).
Safety of the operator, as well as that of the instrument, is only assured when it’s used for its intended purpose
Use for Other than Intended Purpose
Using the instrument for any purposes other than those described in the product documentation is contrary to use for intended purpose.
Liability and Guarantee
Gossen Metrawatt GmbH assumes no liability for property damage, personal injury or consequential damage resulting from improper or incorrect use of the
product, in particular due to failure to observe the product documentation. Furthermore, all guarantee claims are rendered null and void in such cases.
Nor does Gossen Metrawatt GmbH accept any liability for data loss.
