| System pressure protection switch | 2.5MPa closed, 2.45MPa recovery (for reference) |

| Maximum drive voltage | The main power supply voltage shall not be higher than 450VDC, otherwise the controller internal components. |
| Suction and exhaust pressure connection | The torque of the compressor suction and exhaust port of pressure bolt is 11 ± 1 N.M。 |
| Compressor installation Angle | The compressor body should not be tilted (the angle between the compressor main axis and the horizon should not be greater than 5°). |
| else | The electric compressor shall be avoided in the air outlet of the condenser to ensure adequate cooling of the controller. |
| The compressor needs the refrigerant cooling motor and the controller, the suction pipe should be added insulation pipe. | |
| In order to avoid the insulation drop caused by excessive moisture in the system, the compressor suction and vent should be installed into the closed system immediately (within 5 minutes) after opening. | |
| The compressor shall be installed with vibration reduction footpad to achieve vibration reduction and noise reduction purposes. | |
| · The heat dissipation capacity of the condenser should meet the system requirements, and the installation position should have enough heat dissipation space.
· There is energy storage filter capacitor inside the compressor controller. When high voltage is charged, precharging shall be adopted; otherwise, charged pulse current will cause impact damage to the relay and insurance. · Compressor branches recommend separate fuses and are not suitable for combination and use with parts related to vehicle safety (e. g., the same set of relays and insurance). · It is recommended to start the condenser fan 6 seconds before the compressor starts to reduce the pipe pressure; After the compressor stops, the condenser fan delays off for 6-10 seconds. · Under the extreme working pressure and abnormal working pressure, it will increase the failure rate of the compressor and shorten the service life of the compressor.
