3.6.1.1
Protection of the motor cables
-
For functional reasons, the motor cables need not to be protected by fuses
if you only connect a motor per controller.
-
If you want to drive several motors in parallel connected to a controller, an
individual cable protection is required when reducing the cable
cross-section.
