3.5.1 Connecting AC Power Cord
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.
