Recommended Power Outlet
A single-phase 3-core outlet with a neutral point or a multi-functional computer power
socket is recommended. The neutral point of the outlet should be grounded reliably.
Normally, the neutral point of the power supply system in a building is buried in the
ground during the construction and cabling. Verify that the power supply for the
building is grounded before connecting the AC power cord.
