3.7 Drive unit installation
The relation between drive units, drive unit voltage, input
voltage, drive output and interfacing to steering gear are
shown in the table below. The AP11 system detects whether
a reversible motor or a solenoid is connected and outputs
the correct drive signal automatically.
Refer to the connecting diagram for the different drive units
on page 51 onwards.
Installation instruction for the drive units are found in the
manual for the individual units.
