WARRANTY
This product is covered by a warranty against material and manufacturing defects for a 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 61010-1 CAT III 300V class 2 standards for operating voltages up to 300 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 against its accidental use.
• Operation is no longer safe when:
1) There is clearly visible damaged.
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 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.
