Electric Wiring and Application

Note:
1. Please follow the national electrical standards. All provided parts and raw materials must comply with local laws and
regulations. Please employ a professional electrician for installation.
2. Power supply must use the rated voltage and the air conditioning unit should have a dedicated power supply. Power
fluctuations in the power supply ratio should be less than 2%, and where there is an indoor unit, the outdoor machine should
have dedicated power.
3. The power cord should be reliably fastened to prevent the terminal from being stressed. Please do not force the power cord.
4. The power line diameter should be large enough. The ground wire should be reliable and should be connected to the
building's special grounding device.
5. An air switch and earth leakage switch that can cut off the entire system must be installed. The air switch should also have
a magnetic trip and thermal trip function to protect against short circuit and overload and are protected. Please use the "D"
type circuit breaker.
6. To prevent overheating of the capacitor from high frequency waves, do not add the phase-connected capacitor.
7. Please follow the instructions in accordance with the requirements of the power cord connection to avoid a security incident.
8. The unit must be reliably grounded to meet the relevant requirements of GB 50169.
9. All electrical installations must be carried out by professionals in accordance with local laws, regulations and corresponding
instructions.
10. Only copper wire can be used. Breaker for electric leakage should be provided to prevent electric shock.
11. Periodically check and verify the tightened pressure lugs.

Note:
1. Select the power supply cable of each outdoor unit from the following specification: Cable 5-core, in conformance with design
HO, RN-For 60245 IEC 66. The operating temperature cannot be greater than its specified value.
