P-164000249 30-200 kW 13
Revision 2 User's and Installation Guide
The rectifier input switch and battery breaker are available as standard for the 30-50 kW units, and as
optional for the 80-150 kW units. The internal MBS is available as optional for the 30-150 kW units.
These options are not available for the 160-200 kW units, and will have to be included externally in the
installation.
If utility power is interrupted or falls outside the parameters specified in Chapter 8 Technical data
on page 76, the UPS uses a backup battery supply to maintain power to the critical load for a
specified period of time or until the utility power returns. For extended power outages, the UPS
allows you to either transfer to an alternative power system (such as a generator) or shut down
your critical load in an orderly manner. The UPS bypass consists of a continuous-duty static switch
and backfeed protection isolation device K5. The backfeed protection is located in series with the
static switch. Transfers to static bypass are seamless and performed automatically by the system as
needed, for example, in case of an extended system overload.
2.2 UPS operating modes
UPS operating modes:
• Normal operating modes:
• In double conversion mode, the critical load is supplied by the inverter, which derives
its power from rectified utility AC power. In this mode, the battery charger also provides
charging current for the battery, if needed.
• In Energy Saver System (ESS) mode, the critical load is supported securely by utility power
through static bypass switch with double conversion available on-demand with typically
less than a 2 ms transition time, should any abnormal condition be detected in the utility.
When operating in ESS mode, the load is protected with inherent surge suppression.
Operating the UPS in ESS mode increases system efficiency to 99 % allowing significant
savings in energy losses without compromising system reliability.
• In stored energy mode, the energy is drawn from a DC backup power source and converted to
AC power by the UPS inverter. Most commonly VRLA batteries are introduced to the system for
this purpose, and the mode of operation is called battery mode.
• In bypass mode, the critical load is supported directly by utility power through the UPS static
switch.
2.2.1 Normal operating modes
During normal UPS operation, power for the system is derived from a utility input source. “Unit
Online” is displayed on the front panel, indicating that the incoming power is within voltage and
frequency acceptance windows.
2.2.1.1 Double conversion mode
Figure 2-4: Path of current through the UPS in double conversion mode on page 14 shows the
path of electrical power through the UPS system when the UPS is operating in double conversion
mode.
