2 INSTALLATION
Install the chopper baseplate onto a flat metallic surface that is clean and unpainted.
Apply a very 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 contacts, resulting in bad
operation. Remember this point when deciding the installation position on the vehicle.
Fix the chopper using the special holes located on the baseplate (maximum screwing
torque: 3 Nm for M5 and 4Nm for M8 screws).
Verify that the wiring of the cable terminals and connectors has been carried out
correctly.
2.1 CONNECTION CABLES
For the auxiliary circuits use cables bigger or equal to 0.5mm
2
section.
For power connections to the motor (pump and traction rotor) and to the battery use
cables of 16÷25 mm
2 section. The cables from chopper to battery should be run side by
side and be as short as possible.
2.2 CONTACTORS
A Main Contactor, designed for Continuous Operation should be installed. This
contactor should be fitted with a coil corresponding to the battery voltage. The current
absorbed by the coil must not be greater than 2A.
Suppression for this contactor coil is inside the chopper logic. Do not use any
additional external suppression.
2.3 FUSES
- Use a 10A fuse for protection of the auxiliary circuits.
- The power fuse is alrady installed on the chopper by Zapi. For special applications or
requirements this value can be reduced.
