DANGER
(1)The electricians should be licensed.
(2)The air conditioning is Class I appliances and should be grounded reliably.
(3)The grounding resistance should comply with the national standards covered in GB
50169
(4)The yellow-green line is for grounding. Do not use it for other purpose or cut it off or
fixed with the self-tapping screw, otherwise it would lead to electric shocks.
(5)The power supply should be reliably grounded and do not connect the grounding line to
a) running water lines; b) gas lines; c) blow-off lines; d) other unreliable places.
(6)Do not make the power lines and communication lines entwined and arrange them
separately with a distance no less than 20cm, otherwise it would lead to abnormal
communication.
(7)Do not wire improperly power lines and communication lines. When the power line is
wired to the communication port, it would make the main board burnt out.
