output voltage may be set to a nominal 220, 225, 230 or 240 Vac. The UPS’s default setting is 225 Vac.
●Utility failure sensitivity - The UPS’s sensitivity to line voltage distortions may be customized to allow use of the UPS in “noisy” electrical environments or with fuel poweredgenerators. High,mediumandlowsensitivitysettingsmaybechosen. Thehigh setting provides the best protection from all utility voltage vagaries. The medium setting is selected where rapid low amplitude line voltage fluctuations occur frequently as the result of motor load switching in air conditioners, elevators, etc. The low setting is selected when the UPS is operated from an inexpensive fuel powered generator. The UPS’s utility failure sensitivity default setting is high.
●Audible alarm operation - The UPS’s audible alarm beeps four times every 30 seconds in response to failed utility conditions. The alarm beeps continuously when low battery conditions are reached. This is the default operation. Audible alarm operation may be customized such that an indication in response to utility failure is delayed by 30 seconds, silenced until low battery conditions are reached, or muted during both utility failure and low battery conditions.
●Minimum battery capacity to restart - The UPS may be customized so that it will not restart upon restoration of the utility until the battery has been recharged to within 0%, 10%, 25% or 90% of full capacity. This function eliminates unexpectedly short run times when repetitive utility failures occur. The UPS’s minimum battery capacity to restart default setting is 0%.
●Shut down, turn off delay - The UPS’s shut down or turn off delay interval may be customized to 20, 180, 300 or 600 seconds. The UPS’s shut down delay default setting is 20 seconds. Extension of the shut delay is useful where the time between issuance of the UPS shut down command, and actual completion of the operating system shutdown routine is longer than 20 seconds.
