Table 31. Electrical Output Specifications (Continued)
Isolation, Including Output
Neutral to Ground Bonding
The Eaton Ferrups FX UPS provides a true, separately-derived power source, as defined by
National Electrical Code Article 250-5d, with output neutral bonded to ground. There is no direct
connection between input and output, and less than 2 pF of effective input to output
capacitance.
Load Compatibility
UPS supports R, RCD, SMPS, and PFC loads
RCD Loads shall have a minimum power factor of 0.7
Supports Load Crest Factor up to 2.5
Overload Capability
On line with 101 - 124% load, shutdown in 10 minutes
On inverter with 101 - 110% load, shutdown in 10 minutes
On line with more than 125% load, shutdown in 10 seconds
On inverter with more than 110% load, shutdown in 10 seconds
Output Voltage THD <10% at full resistive load, under normal operating conditions and with the batteries fully
charged with the charger in the rest mode.
Short Circuit Protection Shutdown after 3 line cycles of output short circuit that cannot be cleared.
Transfer Time To Battery Transfer to Battery Mode operation from Normal Mode operation in zero milliseconds
Efficiency
The UPS efficiency with Line-to-Line Load shall be > 80% with charger off
The UPS efficiency with Line-to-Neutral Load shall be > 88% with charger off

Table 32. Environmental and Safety Specification
Operating Temperature
0°C to 40°C (32°F to 104°F)
Storage Temperature
UPS with batteries: –15° to 40°C (4° to 104°F)
UPS without batteries: —40° to 60°C (-40° to 140°F)
Relative Humidity
0–95% noncondensing
Operating Altitude
The maximum operating ambient temperature decreases 1° C per 300 m above sea level
(2° F per 1000 ft above sea level). Maximum elevation is 10000 m (32,808 ft )
Ventilation
The air around the UPS must be clean and free of dust, corrosive chemicals, and other
contaminants. The Eaton Ferrups FX UPS uses internal fans to circulate the air for cooling.
The air must be free to circulate around the UPS and external battery cabinet(s). Do not
operate the UPS in a sealed room or container.
Lightning and Surge Protection
The Eaton Ferrups FX UPS provides 2000-to-1 spike attenuation. Tested using lightning
standard per ANSI/IEEE C62.41 Category A (6000V spike and 200A) and Category B
(6000V spike and 3000A) test, and ANSI/IEEE C62.45 test procedures.
