Figure 1-9 UPS Frequency Transfer Points
Frequency
The UPS is designed to operate from nominal 50 Hz or 60 Hz power systems. Selection
between 50 Hz and 60 Hz operation is performed automatically by the UPS at initial
power on. If the input AC line frequency is below the minimum operating frequency, or
above the maximum operating frequency, for either 50 Hz or 60 Hz operation when the
UPS is first turned on, power will not be applied to the AC output. The minimum and
maximum frequency ranges (in Hz) are specified in Table 1-2.
Other key points regarding frequency:
• The UPS has no switches or jumpers to set input or output frequency.
• The unit is auto-ranging; that is, it configures itself to the frequency of the AC input
source.
• The UPS has a wide input range and automatic frequency selection.
