● All electrical connections should be completed by experienced and qualified personnel.
● Turn off the power switch of the power distribution box before the wiring to ensure safety.
● Always use reliable standard cables.
● Do not operate with wet hands.
● Do not place heavy objects on cables.
● Water supply pipes and house steel bars may not be reliably connected to the ground. Please do not
use them for safety grounding.
● Each machine shall be equipped with a gas switch or fuse.
4.2.1 Connection of power cord
Warning! Electric shock may cause death! After the power is off, there is still a high
voltage in the equipment. Thus, do not touch the live parts of the equipment.
Warning! The power supply of the machine must be connected by an experienced
and qualified electrician.
Warning! Do not ground the live wire (blue, brown, and black) of the power cord,
and do not connect the earth wire (yellow-green) to the live wire!
Warning! Excessive input voltage may damage the equipment!
1) Connect the power source to the suitable power distribution box according to the voltage grade of
machine. Meanwhile, ensure that the supply voltage deviation is within the allowable range.
2) When extension cord is required, it is recommended to use power cords with larger
cross-sectional area to reduce the voltage drop. An excessively long cord may affect normal
operation of the system. Therefore, please use the recommended cord length.
Ensure that the switch of the power distribution box is off during the connection of the input power
cord.
Connect the input power cord of the machine to the output of the power distribution box reliably.
