Electric Wiring
Wiring precautions
1. Wiring should conform to national rules. All the parts, materials, electric work should be in accordance with local
codes.
2. Rated voltage and exclusive power supply should be used.
3. Power cord should be fixed soundly and reliable. Never forcibly pull the power cord.
4. Wire size of power cord should be large enough. A damaged power cord and connecting wire should be
replaced by dedicated cable.
5. All the electrical work should be performed by professional personnel as per local laws, regulations and this
manual.
6. Connect the unit to the special grounding device and make sure the unit is grounded properly.
7. Air switch and circuit breaker is required to be set. Air switch should have both magnetic trip and thermal trip
functions to protect the unit when a short circuit or overload happens. D-type breaker is recommended to be
used.
8. Wiring diagram attached on the unit is the most accurate.
