I. AC power socket (recommended)
You are recommended to use a mono-phase three-wire power
socket with a neutral point or a multi-function power socket for
computers. The neutral point of the power in your building must be
well grounded. Normally, the neutral point of the power supply system
in your building has already been grounded during the construction
and wiring; but you should make sure this is the fact.
