WARNINGS: 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.
• Power controllers are designed to assure a switching function that does not include protection of the load line or of devices connected to it. The
customer must provide all necessary safety and protection devices in conformity to current electrical standards and regulations.
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"!
• we recommend installing a cooling fan inside the electrical cabinet near the GTD devices!
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.
• avoid dust, humidity, corrosive gases and heat sources;
• keep away from dust, humidity, corrosive gases and heat sources.
• respect the installation distances between one device and another (to allow for dissipation of generated heat).
• we recommend installing a cooling fan inside the electrical cabinet near the GTD devices;
Maintenance:
• Periodically check the operation of any cooling fans and clean the cabinet air filters 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 compromise the mechanical reliability of the device. To clean external plastic parts, use a clean cloth wet with ethyl
alcohol or water.
