1General information
1.1 Introduction
Thank you for choosing this product. This document is an integral part of the product, as it contains the
procedures and parameters necessary for the assembly, installation, wiring, commissioning and support of
the product.
The buyer and/or qualified person with knowledge of electrical and/or electronic systems who will use the
product need the use and maintenance manual and must keep it available for reference at any moment.
1.2 Safety warnings
Closely follow the precautions given (with warning symbols), as they are crucial for safety:
General danger symbol
Dangerous electrical voltage symbol
1.3 Storage and Installation Environment
Do not store or use the product in the following environments:
Exposed to direct sunlight
Exposed to higher levels of temperature, condensation and relative humidity than ones indicated in
the specifications table
Exposed to dust, salinity, water, oil, chemicals, corrosive or inflammable gases, fuels
Pollution degree higher than 3
When subject to impact or vibrations
1.4 Transport, installation and wiring
Do not drop the product
Grasp the product by the motor, always checking first to ensure it is not hot –burn danger!
Do not install the product if there are damage signs on the packaging or on the product itself
Wiring must be performed by qualified personnel, with the power supply disconnected
During the installation and wiring operations, protect any product openings with appropriate guards
in order to avoid that any kind of conductive metallic object is able to get in
Ensure the connectors are firmly tightened
Install appropriate safety components (fused disconnect switch) up line of the power supply
Use shielded cables in locations subject to static electricity, strong magnetic fields or in the presence
of electrical lines
Use suitable and appropriately sized cables for connection of the power supply, motor and control
signals connections;

1 - General information
6 / 66
For control signal connections longer than 1m, it is recommended to use shielded cables with the
shielding connected to an available earth signal;
Make sure that the power supply voltage complies with the one on the rating plate;
Ensure that there is sufficient ventilation to dissipate the heat produced by the product.
1.5 Operation and adjustments
At first power on or after a period of more than two months of inactivity, it’s recommended to keep
fed the logical part for at least 24 hours;
Activate the product only after checking the compatibility of the load and of the machine in which it
will be installed;
Stay away from the machine when the product is in reboot phase from an error (if the automatic
reboot is enabled), because the machine could restart suddenly;
Do not place body parts near the rotating parts;
Use appropriate personal protective equipment during the work near to the axis ends (presence of sharp
edges in the tongue seat);
Before performing the machine test, provide adequate protections aroundthe rotating parts (joints, etc.);
Never activate the device or its switches with wet hands
1.6 Maintenance and inspection
The product is equipped with a backup battery used for the multi turn position retain. To guarantee
the life performance and expected life it is necessary to perform a complete charge cycle for a
minimum time of 24 consecutive hours every 6 months.
Ensure that all safety precautions have been taken before performing maintenance or inspection
operations
Do not touch the heatsink and the motor as these components heat up when the product is
operational and remain hot even after it is switched off
Do not uninstall the product when it is powered, switch it off then wait at least two minutes before
doing so
Do not change the wiring, the supply voltages, etc. while the product is powered
Do not repair or modify the product
The product does not require any particular preventive maintenance. However, we recommend
performing the following checks regularly:
•Check the condition and tightening of the connections
•Check that the heatsink is clean and ventilated
Do not treat the product as normal domestic waste: it must be taken to an appropriate collection
point for electrical and electronic waste. Failure to observe this requirement can lead to civil and/or
criminal penalties, and could have damaging consequences for the environment and human health.
