3. Check the meter, power supply, power supply wire, switches, sockets compliance requirements.

First, the meter side. Air conditioning consumes more power in the 2200 watts, select meters above the current capacity of 5A; air conditioning consumes more power in the 4400 watts, select the meter's current capacity of 10A or more; air conditioning consumes more power in the 6600 watts, select meters above the current capacity of 15A .

Second, the power supply side. Single-phase power: air conditioning using single-phase supply voltage is 220 volts AC; air conditioning use the normal power supply voltage range is 220 volts AC10% (ie: 198 V -242 V). Three-phase power: air conditioning using the three-phase AC power supply voltage of 380 volts AC; air conditioning use the normal power supply voltage range of AC 380 V10% (ie: 342 V -418 V).

Third, the power wire side. 1 -1.5 hp air-conditioning power cable conductor cross-sectional area should be larger than 2.5 mm; 1.6 -2.5 hp air-conditioning power cable conductor cross-sectional area should be larger than 4.0 mm; 2.6 -3 hp air-conditioning power line cross-sectional area should be large copper at 6.0 mm.

Fourth, the power switch side. 1 -1.5 hp air-conditioning power switch should be greater than 10A; 1.6 -2.5 hp air-conditioning power switch should be greater than 20A; 2.6 -3 hp air-conditioning power switch should be 25 ~ 30A.

Fifth, the power outlet side. 1 -1.5 hp air outlet should be larger than 10A; 1.6 -2.5 hp air outlet should be larger than 15A; 2.6 -3 hp air outlet should be 16 ~ 30A. Special notice is, according to national standards, because of the power cabinet machine, the current is high, the power switch should be used to control the air supply line to ensure the safety of the normal air conditioning use.

Sixth, power equipment requirements. To be equipped with dedicated power lines, obtained by qualified electrical personnel in accordance with the provisions of the national standard wiring. Power outlet should be equipped with easy-plug the power cord in the air-conditioned places, and must be equipped with ground, to ensure that air through the outlet ground. Three-wire plug, the ground and the zero line must be strictly separated from the ground and connected with the zero line is wrong, the power plug and power outlet in the wiring methods and requirements, L logo should be connected to the line of fire; N logo should be connected zero line; ground wire must be connected.
