1.5 AC Power Cable and Connectors
The AC power cable is 4.6 m (15 ft) in length. It consists of
three-phase leads (X, Y, and Z) plus neutral (W/N) and ground
(G). AC power connectors for 60 Hz and 50 Hz systems are
shown below. See Section 6.3.
CAUTION: Neutral and ground lines must both be connected from
the bulk three-phase power to complete the Wye configuration.
Otherwise, power components may be damaged. Power must not
be connected to the site source until the power checks of Chapter 6
are performed.
