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.

The shrink packaging machine and the winding machine both consume a large amount of power, so the input power must be greater than the nominal power on the shrink machine nameplate, otherwise it is easy to burn out the circuit or electrical components.
