Attach the IEC 320 C19 end of the E7801A cord to the
PDU and attach the
L6-20 end of the same cord to the NEMA L6-20 receptacle on the UPS.
Alternate 208 VAC Power Configurations
In the 208 VAC case, without a UPS, make sure your power system has the
capacity to support the power and current needs of the components you will
