3 INSTALLATION
Install the chopper baseplate onto a flat metallic surface that is clean and unpainted.
Apply a thin layer of thermo-conductive grease between the two surfaces to permit
better heat dissipation.
Despite the protection provided against external agents, the continuous attack of corro-
sive elements and substances may cause oxidization of connector contacts, resulting in
bad operation. Remember this point when deciding the installation position on the vehi-
cle.
Fix the chopper using the special holes located on the baseplate.
Verify that the wiring of the cable terminals and connectors has been carried out cor-
rectly. Ensure that suppression devices are fitted to the coils not protected by the
SEM-1C itself.
3.1 CONNECTION CABLES
For the auxiliary circuits use cables better or equal to 0.5mm² section.
For power connections to the motor armature and battery use cable of 16mm² section.
For the Field connections use cable of 4mm² section.
For the optimum chopper performance, the cables to the battery should be run side by
side and be as short as possible.
3.2 CONTACTORS
A Line Contactor, designed for Continuous Operation should be installed. This contac-
tor should be fitted with a coil corresponding to the battery voltage. The current ab-
sorbed by the coil must not be greater than 3A.
Suppression for this contactor coil is within the chopper. Do not use external suppres-
sion. For any Contactor using external suppression, ensure that connections are made
respecting correct polarity.
3.3 FUSES
- Use a 6.3A 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.
