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 quali
fi
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 identi
fi
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 unspeci
fi
ed external voltage.
• The application of currents not compatible with the current inputs levels will
damage to the instrument. supply with extended operating range. The power
supply terminals are numbered (10) and (11). Use cables with max cross-
section of 4 mm2.
