3.5 Precautions for wiring work
Danger
Use high-quality wiring equipment and devices, and carry out wiring work
safely and securely according to the technical standards for electrical
facilities, as well as the indoor wiring regulations.
Only qualified personnel such as licensed electrical engineers are allowed
to carry out electrical wiring work. Unqualified persons are prohibited by
law to carry out wiring work, and it is very dangerous.
Danger
Securely connect the terminals of the power cable. Loose terminals may
cause the motor to run in open-phase condition, thus leading to motor
burnout.
