Antispark function

The KAVAN Smart PRO 120/130 and KAVAN Smart PRO 200/220 controllers contain an additional circuit that can be optionally used to prevent sparks when connecting the drive battery. This circuit is connected to the propulsion using a separate cable. Use the "Antispark" cable only for pre-charging the controller capacitors. Never use this cable to power the motor or any external electronic components.
