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 of 0.5 mm² section.
For power connections to the motor and to the battery, use cables having section
of at least 70 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
The main contactor must be installed. The LC coil driver is voltage controlled by
means of a 1 kHz PWM. The voltage applied to the coil can be adjusted by "Main
Cont Voltage" parameter in Config/Adjustment menu. It has to be adjusted to the
LC coil nominal voltage.
4.1.3 Fuses
- Use a 10 A Fuse for protection of the auxiliary circuits.
- For protection of the power unit, refer to diagrams. The Fuse value shown is
the maximum allowable. For special applications or requirements these
values can be reduced.
- For Safety reasons, we recommend the use of protected fuses in order to
prevent the spread of fused particles should the fuse blow.
4.2 Installation of the hardware
U Before doing any operation, ensure that the battery is disconnected and
when all the installation is completed start the machine with the drive
wheels raised from the floor to ensure that any installation error do not
compromise safety.
