3.3.1 Connecting the AC-Input Power Cord

I. AC-input power socket (recommended)
You are recommended to use a monophase three-line power socket with a ground
contact or a general purpose PC power socket, making sure that the power point is well
connected to building ground. Normally, the ground point of the power source in a
building was buried in the ground during the construction and wiring. Still, you must
make sure of that.
