Site Wiring and Power
The Sun StorageTek 6140 array uses wide-ranging, redundant power supplies that
automatically accommodate voltages to the AC power source or the optional –48-
VDC power source.
The power supplies meet standard voltage requirements for both North American
(USA and Canada) operation and worldwide (except USA and Canada) operation.
The power supplies use standard industrial wiring with line-to-neutral or line-to-
line power connections.
