•Detailed description of the fault and of the operating condition when the fault occurred

The Electrex repair lab will send the authorization number to the customer directly or to the distributor as per

applicable case.

The RMA authorization number shall be clearly marked on the packaging and on the return transport

document.

WARNING: Failure to indicate the RMA number on the external packaging will entitle our warehouse to

refuse the delivery upon arrival and to return the parcel at sender’s charge.

The material must be shipped:

-within 15 working days from the receipt of the return authorization number

-free destination i.e. all transport expenses at sender’s charge.

-to the following address: Electrex S.r.l.

Via Claudia 96 - 41056 Savignano s/P (MO) - Italy

Atn. Repair laboratory

-the units covered by warranty must be returned in their original packaging.

1.3.1 RE-SHIPPING OF REPAIRED PRODUCT

The terms for re-shipment of repaired products are ex-works, i.e. the transport costs are at customer charge.

Products returned as detective but found to be perfectly working by our laboratories, will be charged a fixed

fee (40.00 Euro + VAT where applicable) to account for checking and testing time irrespective of the

warranty terms.

1.3.2 Return Material Authorization (RMA form)

Request for the authorization number for the return of goods

to account for checking and testing time irrespective of the warranty tems.

Space reserved to ELECTREX

R.M.A. No.

The RMA number shall be clearly indicated on the external packaging and on the shipping document:. Failure to observe this

requirement will entitle the ELECTREX warehouse to refuse the delivery.

2 Safety

This instrument was manufactured and tested in compliance with IEC 61010 class 2 standards for operating

voltages up to 250 VAC rms phase to neutral.

In order to maintain this condition and to ensure safe operation, the user must comply with the indications

and markings contained in the following instructions:

•When the instrument is received, before starting its installation, check that it is intact and no damage

occurred during transport.

•Before mounting, ensure that the instrument operating voltages and the mains voltage are

compatible then proceed with the installation.

•The instrument power supply needs no earth connection.

•The instrument is not equipped with a power supply fuse; a suitable external protection fuse must be

foreseen by the contractor.

•Maintenance and/or repair must be carried out only by qualified, authorized personnel

•If there is ever the suspicion that safe operation is no longer possible, the instrument must be taken

out of service and precautions taken against its accidental use.

•Operation is no longer safe when:

1) There is clearly visible damage.

2) The instrument no longer functions.

3) After lengthy storage in unfavorable conditions.

4) After serious damage occurred during transport

The instruments must be installed in respect of all the local regulations.

2.1 Operator safety

Warning: Failure to observe the following instructions may lead to a serious danger of death.

-During normal operation dangerous voltages can occur on instrument terminals and on

voltage and current transformers. Energized voltage and current transformers may generate

lethal voltages. Follow carefully the standard safety precautions while carrying out any

installation or service operation.

-The terminals of the instrument must not be accessible by the user after the installation. The

user should only be allowed to access the instrument front panel where the display is

located.

-Do not use the digital outputs for protection functions nor for power limitation functions. The

instrument is suitable only for secondary protection functions.

-The instrument must be protected by a breaking device capable of interrupting both the

power supply and the measurement terminals. It must be easily reachable by the operator

and well identified as instrument cut-off device.

-The instrument and its connections must be carefully protected against short-circuit.

Precautions: Failure to respect the following instructions may irreversibly damage to the instrument.

-The instrument is equipped with PTC current limiting device but a suitable external protection

fuse should be foreseen by the contractor.

-The outputs and the options operate at low voltage level; they cannot be powered by any

unspecified external voltage.

-The application of currents not compatible with the current inputs levels will damage to the

instrument.

3 Mounting

3.1 Dimensions (mm)

3.2 Fixing and blocking

The connection terminals of the instrument are held in place by a plastic panel, which must be mounted

using 4 screws (supplied). This set up will prevent the disconnection of the current measurement terminals.

4 Wiring Diagrams

4.1 Power Supply

The instrument is fitted with a separated power supply with extended

functioning range. The terminals for the power supply are numbered

(13 and 14). Use cables with max cross-section of 4 mm2.

4.2 Measurement Connections

4.2.1 Voltage connection

Use cables with max cross-section of 4 mm2and connect them to the terminals marked VOLTAGE INPUT

on the instrument according to the applicable diagrams that follow.

4.2.2 Current connection

It is necessary to use external CTs with a primary rating adequate to the load to be metered and with a 5A

secondary rating. The number of CTs to be used (1, 2 or 3) depends upon the type of network.

Connect the CT output(s) to the terminals marked CURRENT INPUT of the instrument according to the

applicable diagrams that follow.

Use cables with cross-section adequate to the VA rating of the CT and to the distance to be covered. The

max cross-section for the terminals is 4 mm2.

N.B. The CT secondary must always be in short circuit when not connected to the instrument in order to

avoid damages and risks for the operator.

Warning: THE PHASE RELATIONSHIP AMONG VOLTAGE AND CURRENT SIGNALS MUST BE

CAREFULLY RESPECTED. ALL DISREGARD OF THIS RULE OR OF THE WIRING DIAGRAM

LEADS TO SEVERE MEASUREMENT ERRORS.
