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.
- Refer to the data listed in ”Operation with mains filter/mains choke”
