With the two non-interchangeable types of connectors (A-type, B-type) it is impossible to produce a short circuit. Mating connectors (combination) are identified by mechanical keyways and by color:
- A-type (POWER-IN)
Cable connector: blue
Chassis connector: blue

- B-type (POWER-OUT)
Cable connector: grey, with blue bushing
Chassis connector: grey
