4 INSTALLATION HINTS
In the description of these installation suggestions you will find some boxes of
different colours, they mean:
4
These are informations useful for anyone is working on the installation, or a
deeper examination of the content
U
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 a
minimum section of 15 mm².
For the optimum inverter performance, the cables to the battery should be run
side by side and be as short as possible.
4.1.2 Contactors
IT IS STRONGLY RECCOMENDED TO USE A MAIN CONTACTOR 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; this feature is useful to decrease
the power dissipation of the contactor coil.
U
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.
