Figure 46: Angular connection of motor connectors to controller cables. Connections must be isolated with shrink hose!
Only use high current connector systems between the motor, converter and the battery. The connectors have
to be checked before every use. If the coating is used up, the internal discs and the jacks may be damaged or
lose their resilience, and they have to be replaced.
Shoddy or used up connectors are the most common reason for destructions of the drive, the controller and
possible components around it.
The electric connectors and cables must be connected professionally and have to be isolated with a shrink
hose.

Mixing up the polarity of the battery or a short circuit leads to a destruction of the drive and means an acute
fire hazard and danger of life!
