DC Power Supply
DC motor power
is the same as the
supply voltage
The RS 485 data line
to the PC (optional)
Voltage: 12Vdc or
24Vac, depending on
the maximum power of
the pluggable motors:
• 12Vdc version
= 600 W
• 24Vdc version
= 600 W
By removing a jumper
and inserting the
“in ignition” contact in
its place, the electronics
can be powered only
when the vehicle is
switched on
Power input WITH IGNITION ON.
Given the DC systems' high power
absorption, the motor should be powered
while the battery is being recharged
