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 essen-
tial 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 (inflammable
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 installation
at regular intervals.
• Repairs must be performed only by specialized or appropriately trained personnel. Cut off power to the device before accessing
internal parts.
• Do not clean the box with solvents derived from hydrocarbons (trichloroethylene, gasoline, etc.). Using such solvents will compro-
mise the mechanical reliability of the device. To clean external plastic parts, use a clean cloth wet with ethyl alcohol or water.
Technical service : GEFRAN has a technical service department. Defects caused by use not conforming to the instructions are exclu-
ded from the warranty.
