Eaton BladeUPS (12 kVA) User's Guide
BladeUPS 12 model only. Standard operation (continuous double-conversion) is available
only for loads less than 10 kW (85%). If the load exceeds the 10 kW limit while on
Standard operation, the UPS will switch back to High Efficiency operation until the
load is reduced below 9 kW. After three attempts within one hour to operate on
Standard, the UPS will lock back into High Efficiency operation for one hour to prevent
continuous cycling.

Battery Mode

When the UPS is operating during a power outage, the alarm beeps once every five
seconds and the indicator illuminates solid.
When the utility power returns, the UPS transfers to Normal mode operation while
the battery recharges.
If battery capacity becomes low while in Battery mode, the
slowly and the audible alarm becomes continuous. If the Battery Low alarm is set, the
indicator also illuminates solid. This warning is approximate, and the actual time to
shutdown may vary significantly.
NOTE Depending on the UPS load and the number of Extended Battery Modules (EBMs), the Battery Low
warning may occur before the batteries reach 25% capacity. See Table 22 on page 132 for estimated
runtimes.
When utility power is restored after the UPS shuts down, the UPS automatically
restarts. UPSs in a parallel system stagger their return from Battery mode by 500 ms,
beginning with UNIT 1.

Bypass Mode

In the event of a UPS overload or internal failure, the UPS transfers your equipment to
utility power. Battery mode is not available and your equipment is not protected;
however, the utility power continues to be filtered passively by the UPS. The
indicator illuminates.

S
The user activates Bypass mode through the front panel.

module.

Standby Mode

When the UPS is turned off and remains plugged into a power outlet, the UPS is in
Standby mode. The indicator is off, indicating that power is not available to your
equipment. The battery recharges when necessary.
