Electrical connection of split cooling
The power cable of the indoor unit and the communication cable with the central monitoring host have been
connected before delivery. The power and communication cables between the outdoor unit and the indoor unit
need to be connected onsite.
•
All wiring must conform to local standards. Check that the power supply complies with the requirements on the
nameplate.
•
To avoid corrosion and overheating of the terminals, all required power supply wires must be copper wires.
•
The power cable connected to the electrical control box should be selected according to the maximum
operating current on the nameplate. The total power supply should have a certain margin with recommended
value of 1.25 to 1.3 times the nominal specification.
•
The current carrying capacity of the power supply cable (cord) should be slightly greater than the maximum
operating current of the unit, and the influence of the working environment should be considered.
