Theory of Operation

The ON Series UPS has two operating modes: Conditioned AC Power and Conditioned Battery Backup.

Fig. 1: ON Series UPS Block Diagram

AC Power Mode When AC input power is present and within the correct voltage range, the UPS provides fully conditioned power:

• Computer-based equipment is protected from harmful transient voltage spikes and other electrical noise.

• UPS detector circuits continuously monitor theutility power for blackout, low voltage, and overvoltage events.

During extended low voltage periods the UPS useONBoost® technology to conserve battery power.

Theory of OperatWhen a line sag is detected, ONBoost raises the output voltage to keep it within an acceptable rang

NOTE: The ONBoost function is not available whileon bypass. The UPS will automatically switch to normal output voltage mode when “bypass” is selected. ONBoost operation is indicated by lightinof the decimal point on the right side of the display

Battery Backup Mode

In a severe over- or under-voltage situation, the microprocessor control circuits determine that AC power is no longer in an appropriate voltage rangeThe UPS rapidly switches to battery power to suppcontinuous conditioned power.

While in backup mode, detector circuits monitor threturn of AC power. The UPS synchronizes with thAC source frequency when utility power is availableThe AC source must be stable for 4-5 seconds befothe UPS will return to the AC source from battery. Ino further interruption occurs, the UPS switches toAC power mode. The load equipment is supplied continuously with conditioned power even when running in battery backup mode.

If the battery becomes exhausted while maintaininthe load, a low battery warning is sounded, displayeon the front panel, and transmitted via the communications port a minimum of two minutes prior to termination of battery backup. Once batterbackup terminates, the UPS output turns off. The UPS monitors the line and provides output when utility power is restored to normal operating range

Load Start-up The UPS front panel display may initially show “c8”or “c9” during the load power-up sequence due tomomentary current surges. The display returns to“99” or less when the load is in range.

Fig. 2: UPS Front Panel Display

Output Overload Protection

The UPS output is constantly monitored. If the output is loaded to more than 105 percent of the UPwatt rating, battery power to the load is not availablThe digital display for output overload is “c8.” If theoutput load exceeds 125 percent, “c9” is displayedand the output turns off completely after two seconds. The digital display reads “c9” (or “c1” if theinput circuit breaker has opened).

To reset the UPS, turn the UPS front panel switch“OFF.” Reduce the load or reset the breaker (if necessary) and then turn the UPS front panel swit“ON.” (See Input Protection on page 9 for more information.)

For individual outputs that have circuit breakers, excess current may open these breakers without overloading the UPS. Reduce or redistribute the loaand reset the circuit breaker. (See figure 3 on page

Setup Precaution CAUTION: Do not attach laser printers to the UPS.A laser printer draws high power during use and may overload the UPS.

ATTENTION: To reduce the risk of fire, connect only to an agency-listed circuit breaker; 30 amps fothe ON3300 or 50 amps for the ON3305 and ON5000. Maximum branch circuit overcurrent protection must be in accordance with the NEC, ANSI, NFPA70.

Environmental Considerations

Ambient operation is 10,000 feet (3,000 meters) maximum elevation; 0 to 95% humidity, non-condensing; and 32°F to 140°F temperature(0°C to 40°C temperature).

Long Term Storage

Improper long-term UPS storage may damage theUPS battery and invalidate the battery warranty. Unplugging a UPS from its AC power source for aextended period of time results in reduced batterycharge. The system code may show a “c4” for 2 –hours per battery cabinet after utility power is restored.

To keep the batteries fully charged and to maximizthe life of the batteries, connect the UPS to a properly wired input power source while it is in storage.

If the UPS is stored without input power, connect ito a power source for a minimum of 24 hours at leaonce every 4 – 6 months.

ATTENTION: If the unit will be stored without input power, be sure all battery breakers are in the “OFF”position.

Basic Interface Specifications

The Basic interface primarily supports systems thause signals indicating “AC Line Fail” and “Low Battery” as status inputs to monitor software. Thesindications are provided as RS232 level signals atpins 5 and 8, again with pin 7 as signal ground. A “condition not true” voltage level is at –5V (or less)indicates AC Line or Battery Voltage is okay while a“condition true” voltage level is at +5V (or higher) indicates the AC Line has failed or the Battery Voltage is low. An interface cable, such as ONEAC’CA-NTMERIDIAN, connects the UPS to systems with software configured to respond to these outpu

In Basic Interface Mode, the “Shutdown” signal atpin 20 can turn off the UPS during battery backupoperation if the jumper on the Basic Interface PCB set for it to be enabled. Remove the PCB and movthe jumper on P3 to pins 2 and 3 to enable “Shutdown”. Also check that P4 is set to 3-5 and 4-(factory default). When enabled, a positive voltage (to 24VDC with respect to pin 7) shuts down the UPInverter to conserve the remaining battery charge.voltage at (or below) ground allows the Inverter torun. See On Line or Inverter Remote Off InterfaceSpecifications on page 34 for further information.

Split Interface Specifications

The UPS allows both the full-duplex communications at pins 2 and 3 as well as the stasignaling at pins 5 and 8 to be enabled simultaneously. Together, these can support both network server using the Advanced Interface as weas a computer or other device using the Basic Interface. ONEAC’s “Y-shaped” accessory cable ONEPLUS‚is available for this purpose. By using this cable, the Shutdown signal can be enabled bymoving the P3 jumper to pins 2 and 3 on the I/O PCB.
