When the machine is specified to have a three-phase 380V power supply, the zero line must be input simultaneously, which is similar to other packaging equipment in the standard three-phase four wire system, such as vacuum packaging machines. Otherwise, the machine will not function properly and it is highly likely to burn out internal electrical components. The machine must be installed horizontally, otherwise it will shorten the service life of the electric heating tube. For machines with conveyor belts, their inclined installation will cause the conveyor belt to deviate from the center.

Machines like packaging machines must be reliably grounded to protect personal safety. Each machine comes with a power cable that is connected to the power supply when it leaves the factory. The end lead of the cable has an identification symbol for the power supply and must be connected correctly. Violating regulations may cause electric shock.
