These are Warning boxes , they describe:
- operations that can lead to a failure of the electronic device or can be
dangerous or harmful for the operator;
- items which are important to guarantee system performance and safety
4.1 Material overview
Before to start it is necessary to have the required material for a correct
installation. Otherwise a wrong choice of cables or other parts could lead to

failures/ misbehaviour/ bad performances.
4.1.1 Connection cables
For the auxiliary circuits, use cables 0.5mm² section at least.
For power connections to the motor and to the battery, use cables having section
of 16-25 mm².
For the optimum inverter performance, the
and be as short as possible. side by side
4.1.2 Contactors
IT IS STRONGLY RECCOMENDED TO USE A MAIN CONTACOTOR to
connect and cut off the battery to the controller. Depending on the setting of a
parameter in the controller:
-
the output which drives the main contactor coil is on/off (the coil is driven with
the full battery voltage).
- the output which drives the main contactor coil is switched at high frequency
(1 KHz) with a programmable duty cycle; th
the power dissipation of the contactor coil.
The EN1175 states the main Contactor is not mandatory (under proper
conditions); anyway it is recommended to protect the inverter against
reverse battery polarity and to cut off the battery from the power mosfets
when a failure in the three phase bridge occurs.
