On page 1-1, under "Site Electrical Requirements":

ALL POWER CENTER MODELS REQUIRE A DEDICATED 220 Volt single phase 30 amp
power line.

A dedicated line must provide 220 current in the following range:

	o	195-240 Volts of single phase AC
	o	47-63Hz

A POWER Center can draw a maximum of 24 amps from the 220 Volt line 
(depending on configuration of the POWER Center).  The POWER Center
has a maximum VA of 5280.

The NEMA receptacle (for domestic installations) must have the following
characteristics:

	o	NEMA L6 - 30R (250V @ 30 amps) Twist Lock

p.s.  Markb--I don't think a 110vac on both sides of a three prong plug
	is a code violation.  All US 220 standards I am familiar with
	are twist lock (circular) or triangular pattern (like on the
	"average family electric clothes dryer).
