Balancing Receptacle Loads
For Powerware 9170 UPS models with low-voltage output receptacles, it
is recommended to divide loads between upper and lower receptacles
as equally as possible. (In some configurations, each set of receptacles
is limited to one half of the total UPS capacity.) Whether the cabinet
has one panel containing eight receptacles, two panels containing
16 receptacles, or three panels containing 24 receptacles, you should
try to supply half of the UPS output through the upper half of the
receptacles (X1) and the other half through the lower half of the
receptacles (X2), as shown in Figure 44.
