share control algorithms maintain synchronization and load balance by constantly making minute
adjustments to variations in the output power requirements. The modules conform to demand and are not
in conflict with each other for the load. The Powerware Hot Sync systems are capable of paralleling for
both redundancy and capacity.

The Power Conditioner mode is characterized by the UPS running in the double conversion mode without
a DC source connected. In the Power Conditioner mode, the UPS provides conditioned output voltage
and frequency. The UPS can also support high nonlinear loads without ITHD on the input. The UPS meets
the qualifications outlined in this product specification, except for the conditions below.
When in the Power Conditioner mode, the UPS has the following functionality and limitations:
1. The UPS runs in the double conversion mode and the battery alarms are turned off.
2. Because there is no DC source, loss of utility power results in the UPS losing power and shutting
down.
3. The UPS sustains up to -50% input voltage tolerance, unless the current limit is reached.
4. If the rectifier is turned off, the UPS attempts a transfer to the bypass mode.
5. The ESS mode is not available.

The Frequency Converter mode is characterized by the UPS running without the bypass mode available.
The output frequency can be configured to be different from the standard input frequency (for example, 60
Hz output, 50 Hz input). The UPS can also support high nonlinear loads without iTHD on the input. The
UPS meets the qualifications outlined in this product specification, except for the conditions below.
When in the Frequency Converter mode, the UPS has the following functionality and limitations:
1. Operation is the same as when in the double conversion mode with no bypass available.
2. Bypass alarms are suppressed.

The Eaton Sync Control maintains the critical load outputs of two separate single UPS systems in
synchronization. Use of the Eaton Fixed Master Sync Control provides uninterrupted transfer of the load
from one load bus to another by means of downstream, dual-source, solid-state transfer switches. Without
the load sync option, the two system output (critical load) buses can become out of phase with each other.
This condition occurs when suitable bypass sources are not available or when the bypass sources feeding
each system are not in sync with each other. Examples of this condition are two systems supplied by
separate generator sets, or situation where the bypass sources for the two systems are lost.
