If the total load requirements of the equipment exceeds the capacity of
the UPS, you must either reduce the number of pieces of equipment, or
use a UPS with a larger load capacity.
NOTE Line-to-neutral loads (100V - 127V) should be balanced between L1/A and
L2/B.
When deciding on which pieces of equipment to remove from the UPS,
select equipment that has a lower priority for power protection.
Computers, monitors, and modems typically have a higher priority
because they could be processing or transmitting data when a power
outage occurs.
Battery Times
The Powerware 9150 UPS has internal batteries with run times up to
17 minutes. If additional run time is required, optional external battery
cabinets (EBCs) can be purchased. There are two EBC models available:
EBC-48 and EBC-96. The EBC-48 model contains 48 batteries and the
EBC-96 model contains 96 batteries. The following table shows
approximate battery times for both internal battery models and the
optional EBC configurations. The times shown in the EBC rows are
cumulative and include the internal battery time.
