Explanation
        
1. The wiring diagram is suitable for high voltage three-phase three-wire system, low voltage three-phase four-wire system, regard to other system wiring please refer to KPM53 instruction manual.
        
2. Analog output AO- and switch input common COM share one terminal.
        
3. Terminal that without function description is invalid.
        
4. The function of dotted lines is optional.
        
5. The final interpretation belongs to Compere.
