Note: ________________________________________________________________
Each AC power source should be independent of the other in order to have
power redundancy. If you do not require power redundancy, the unit can be
operated with a single power cord connected to a single AC power source. In
this case, either AC power connector on the rear of the Multi-Station Power
Supply may be used for the connection.

cord, it whould have a wire gauge of at least 16 and a 230VAC 7A rating.
