WARNING: this symbol indicates danger.
Before installation, please read the following advices:
• follow the indications of the manual scrupulously when making the connections to the instrument.
• use a cable that is suitable for the ratings of voltage and current indicated in the technical specifications.
• if the instrument is used in applications where there is risk of injury to persons and damage to machines or materials, it is
essential that it is used with an auxiliary alarm device.
It is advisable to verify frequently that the alarm device is functional even during the normal operation of the equipment.
• The instrument must NOT be used in environments where there could be the presence of dangerous atmospheres (inflamma-
ble or explosive).
• During continuous operation, the heatsink may reach 100°C and remain at a high temperature due to thermal inertia even
after the device is switched off. Therefore, DO NOT touch the heat sink or the electrical wires.
• do not operate on the power circuit untless the main supply is disconnected.
• DO NOT open the cover if device is "ON"!
(use the holes in the cover for eventual re-calibration).
Installation:
• connect the device to the ground using the proper ground terminal.
• the power supply wiring must be kept separate from that of inputs and outputs of the instrument; always check that the supply
voltage corresponds to that indicated on the instrument cover.
• evitare la polvere, l' umidità, i gas corrosivi, le fonti di calore.
• keep away from dust, humidity, corrosive gases and heat sources.
• The connection cable must be shorter than 3 meters if the current transformer is used.
Maintenance: Check the correct operation of the cooling fans at regular intervals; clean the ventilation air filters of the installa-
tion at regular intervals.
• Repairs must be performed only by specialized or appropriately trained personnel. Cut off power to the device before acces-
sing internal parts.
• Do not clean the box with solvents derived from hydrocarbons (trichloroethylene, gasoline, etc.). Using such solvents will
compromise the mechanical reliability of the device. To clean external plastic parts, use a clean cloth wet with ethyl alcohol or
water.
