SYSTEM OVERVIEW
This Standby UPS protects computers, servers, telecom systems, VoIP systems,
security systems, and a variety of electronic equipment from blackouts, brownouts,
overvoltages, and surges. During normal AC operation, the UPS will quietly and
confidently protect your system from power anomalies.
CHARGING THE BATTERY
The UPS will charge the internal batteries whenever the UPS is connected to an AC
source and there is an acceptable AC voltage present (95 - 140VAC). It is recommended that the UPS's batteries be charged for a minimum of 4 hours before use.
The UPS may be used immediately, however, the “On Battery” runtime may be less
than normally expected. Typical battery life is 3 to 5 years. Environmental factors
do affect battery life. High temperatures, poor utility power, and frequent, short
duration discharges have a negative impact on battery life. NOTE: If the UPS is
going to be out of service or stored for a prolonged period of time, the batteries
must be recharged for at least twenty-four hours every ninety days.
POWER MONITORING SOFTWARE
The EN550 supports Minuteman's SentryHD power monitoring software. Please
go to our web site at www.minutemanups.com/support, then look under Downloads,
and then Software Download Center. Please download (Free of Charge) the latest
version of the Minuteman SentryHD software.
Chapter 4: Operation
The UPS will charge the batteries with the UPS in the on or off position as long as
the UPS is plugged into the wall outlet and there is an acceptable AC voltage present
(95 - 140VAC). When a blackout, brownout, or an overvoltage condition occurs;
the UPS will transfer to the battery mode, the On Battery indicator will illuminate and
the audible alarm will sound once every five seconds indicating that the commercial
power is lost or unacceptable. When the commercial power returns or is at an
acceptable level, the UPS will automatically transfer back to the AC normal mode
and start recharging the batteries. During an extended outage when there is approximately two minutes of backup time remaining the audible alarm will sound
twice every five seconds. This Low Battery Warning is informing the user that they
should save all open files, turn off their computer and then turn off the UPS. When
the batteries reach the predetermined level the UPS will automatically shutdown
protecting the batteries from over discharging. Once the commercial power returns the UPS will automatically restart, providing safe usable power to the connected equipment and start recharging the batteries.
