6 Electric wiring

6.1 Safety precautions

• The electricians should be licensed.
• The air conditioning is Class I appliances and should be grounded reliably.
• The grounding resistance should comply with the national standards covered in GB 50169
• 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, other wise it would lead to electric shocks.
• 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.
• 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.
• 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.
