The controls described in this manual are to be considered and are sold as finished products to be installed only by
qualified personnel. Installation must be done in accordance with all safety regulations for the prevention of risks and
accidents applicable in the country of use.
Notes before energizing:
The controls for electric motors are able to produce high forces and rapid movements, therefore a high degree of
attention is required in their use, especially in the installation and application development phases.
The controls must be installed in a closed electrical panel so that none of its parts can be reached in the presence of
voltage.
Working on electric vehicles is potentially dangerous. Take all available precautions against burns, direct contact or
inhalation of acids, etc. (wear safety glasses, gloves, etc.).
Always follow the recommendations provided by the manufacturer of the batteries as they can deliver high currents in
the event of short circuits: completely disconnect the batteries before any intervention on the system (wiring operations,
checks on connections and various operations).
Controls for moving electric vehicles could cause you to lose control and create dangerous situations.
Disconnect the traction motor or lift the vehicle (also make other motors that could cause damage to persons or property
in appropriate safety) before starting any work on the circuits / connections.
The controls are protected against moisture by surface painting and direct circuit contacts with a partially open cover.
Place the controls in a dry, clean and ventilated position; avoid contact, in any form, with liquids such as water,
detergents, acids, oxides, etc.
The controls are high-powered devices and include various safety management of the electric vehicle.
The complete safety of the application cannot be left to control alone but must be integrated with the risk analysis of the
entire system by the manufacturer of the final machine.
Provide suitable fuses, battery disconnect switches (power switches, contactors, etc.), safety electro-brakes or
mechanical brakes and any other external component to safeguard the system and increase the safety level of the
electric vehicle.
In the event of a breakdown or serious alarm, assess in relation to the application whether the action of disconnecting
power from the motors is the best solution in terms of vehicle safety.
Avoid excessive length connections between controls, power source and motors.
The controls use the high-frequency PWM technology which may produce electromagnetic disturbances, partially already
filtered inside the circuits but which may not be sucient in the final system due to the complexity or execution of the
system itself. It is advisable to build the system with cables of reduced length and to appropriately separate the power
cables from the signal ones. If necessary, use shielded cables or external filters to reduce electromagnetic disturbances.
