Primary Rack Power

Power Phase Imbalance
If you have a single-phase power control compartment,
you will supply single-phase AC power. However, if you
have a two-phase power control compartment, you will
have to supply three-phase power. The two-phase power
control compartment only uses phases 1 and 2 and the
neutral of incoming three-phase power. This may result in
a power imbalance for the three-phase power system. This
imbalance of power increases as the number of installed
racks in your system increases.
Note:
If you have a two-phase power control compartment,
you should consult an electrician to properly balance
the incoming three-phase power.

CAUTION
The plug on the power cord is approved for use
with this machine and meets the relevant testing
laboratory or country/test-house standards. For
the user's safety, the plug must be connected to a
properly wired and grounded receptacle. An
improperly wired receptacle could place a
hazardous voltage on accessible metal parts of
the machine and on the metal housing of the plug
and receptacle. The customer is responsible for
receptacle wiring.
