WARRANTY
This product is covered by a warranty against material and manufacturing defects for a
period of 24 months period from the manufacturing date.
The warranty does not cover the defects that are due to:
• Negligent and improper use
• Failures caused by atmospheric hazards
• Acts of vandalism
• Wear out of materials
• Firmware upgrades
Akse reserves the right, at its discretion, to repair or substitute the faulty products
The warranty is not applicable to the products that will result defective in consequence of a
negligent and improper use or an operating procedure not contemplated in this manual.
RETURN AND REPAIR FORMALITIES
Akse accepts the return of instruments for repair only when authorized in advance. The
transport costs are at customer charge.
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 fl at fee to account for checking and testing time irrespective of the warranty
terms.
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 qualifi ed, 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 againstits 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.
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 identifi ed 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 unspecifi ed external voltage.
• The application of currents not compatible with the current inputs levels will damage
to the instrument.

Normal Classic Alarm with reference to a fi xed threshold or to maximum and minimum delay
and applicable hysteresis. “AVG” parameter is not used.
1-OF-3 Consider also the 2 following registers of the selected one in “MEAS” . Works on a fi xed
max or min threshold with delay and applicable hysteresis. If one of the three register
exceed the threshold the alarm goes on. “AVG” parameter is not used.
3-OF-3 Consider also the 2 following registers of the selected one in “MEAS”. Works on a fi xed
max or min threshold with delay and applicable hysteresis. When all the three register
exceed the threshold the alarm goes on. “AVG” parameter is not used.
DERIV “THRE” parameter becomes a % value, “AVG” parameter is used. The instant value
applied to the alarm on “MEAS” is compared with its value mediated obtained on the
basis of the time set on “AVG”. When the instantaneous value combined alarm diff ers
in more (setting “Max”) or less (setting “MIN”) from the average value (“ AVG “) of the
percentage set on “THRE” the alarm goes on. With delay and applicable hysteresis.
UNBAL Consider also the 2 following registers of the selected one in “MEAS”. “THRE”
parameter becomes a % value. Alarm goes on when one of the three register is
diff erent from the percentage set on “THRE” comply with the higher value of the three
read register if “MAX” is set on “TYPE”, or comply with the lower value of the three
register if “MIN” is set on “TYPE”
With delay and applicable hysteresis.

Voltage connection
Use cables with max cross-section of 2,5 mm
2
if fl exible 4 mm2 if rigid and connect them to the terminals marked voltage input on the instrument according to the applicable diagrams
that follow.
Current connection
It is necessary to use external CTs with a primary rating adequate to the load to be metered and with a 5A or 1A 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 I1, I2, I3 (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, the P1-P2 orientation and the S1-S2 connection of the CT(s) must be carefully respected.
All disregard of this rule or of the wiring diagram leads to severe measurement errors.
