secondary nominal currents:

.../1 A or .../5 A

•

All models are three phase digital

Energy Meter with 2 tariffs and with

IR lateral communication

available.

The built-in communication depends on the model:

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.

of a parameter

◾

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.
