2OperationInstruction manual IM1002004E September 2015 www.powerquality.eaton.comOperationThe Power-Sure 700 is operated by simply turning on themain AC input circuit breaker. All units 50 kVA and larger areequipped with a bypass switch as a standard feature. Forunits 45 kVA and smaller, the bypass switch is optional. Thisis a no load switch and MUST only be operated when theunit is OFF. The bypass switch should be in the “NORMAL”position unless a problem occurs with the system. If aproblem occurs, turn OFF the main AC circuit breakerand turn the bypass switch to the “BYPASS” position.Re-energize the system by turning on the AC circuit breakerand contact the Customer Support Department for repairs.Any “ALERT” condition requires the main AC input breakerto be turned off in order to reset the “ALERT” light.FOR ASSISTANCE, CALL 1-800-809-2772, option 4, andthen option 2.Benefi ts of owning and using thePower-Sure 700●● Line harmonic filtering●● Small physical size●● Simple and inexpensive installation●● Highly efficient●● Quiet operation●● Low BTU output●● Low failure rate●● Seven-tap, microprocessor control and diagnostics●● UL® Listed to 1012 standards●● Priced to be affordable●● Conservatively rated●● Extremely high surge capability●● Simple operation●● Input electronic circuit breakers●● Nationwide customer support serviceSpecifi cations●● Dynamic electrical specifications●● Output: maintained to within ±3% of nominal a●● Input: +10% to –23% of the nominal rated input ab●● Frequency: 60 Hz ±3 Hz a●● Input power factor: >0.99 PF with resistive load●● Line regulation: output is ±3% of nominal for inputvariations of +10% to –23% of nominal●● Load regulation: output maintained within 3% from noload to full load●● Response time: <1/2 cycle●● Correction time: output will correct to within ±3% ofnominal in 1.5 cycles or less●● Harmonic distortion: Less than 1.0% THD added tothe output waveform under any dynamic linear loadingconditions presented to the line regulator●● Transverse-mode noise attenuation: 3 dB down at 1000 Hz,40 dB/decade to below 50 dB with resistive load●● Common-mode noise attenuation: 146 dB●● Audible noise: 45 dB or less●● Turn on characteristics: when energized, voltageovershoot will be less than 5% of nominal for 1 cycleor less●● Overload rating: 1000% for 1 cycle and 200% for10 seconds●● Ambient rating: –10º to +40º Celsius●● Integral manual rotary maintenance bypass switchstandard on 50 to 500 kVA units and optional onsmaller unitsotes:N 50 Hz models available.Figure 1.
