Notes
1. This drawing shows the electrical circuit of CO2 condensing unit.
2. Dotted line (----- ) shows the wiring on site.
Long dashed double-short dashed line (----- ) shows installation on site.
3. Separate signal line from power line.
4. CNG1,CNG2,CNS1,CNS2 and CNS3 are no voltage contact inputs.
If they will be used, use the attached harness for level input.
5. Output of CNH,CNY,CNZ1 and CNZ2 is 12V. Maximum current is less than 20mA (+ side (1 PIN side) is common) .
If they will be used, use the attached harness and be sure to connect to unit relay (Coil resistance of 7502 or more
provided on site).
