Operation

BATTERY TEST MODE:

To verify battery backup operation of your UPS, you can periodically perform a manual or programmed self-test of the UPS system. To

manually initiate a self-test while the UPS is operating in On-Line or Economy mode, press the ON/MUTE switch until a beep is heard,

then release. The UPS can be configured via the front panel LCD interface for no test, weekly or monthly self-test (factory default

configuration: monthly). Self-test can also be initiated via PowerAlert software at user determined intervals (see PowerAlert software

documentation for more information). When a self-test is run, the UPS will cycle to battery power for approximately 10 seconds and

automatically switch back to AC mode. If a failure mode or low battery condition is encountered, UPS will report “BATTERY FAULT” alarm

message and beep briefly once every two seconds. If the battery is okay, the display will return to the previous menu.

BATTERY MODE LEDs: INPUT, BATTERY, AC/DC, OUTPUT LEDs on. BATTERY MODE LCD SCREEN: BATTERY TEST and UPS load

BATTERY TEST MODE LCD VIEWING OPTIONS:

None—for the duration of the battery test the display will report output loading information.

The advanced frequency conversion setting is accessible through the LCD, the included PowerAlert software or the optional

SNMPWEBCARD internal accessory card. When continuous frequency conversion is enabled, the maximum output capacity of the UPS

system is derated by 30%. To set the UPS for frequency conversion, you’ll need to adjust settings on two separate LCD configuration

screens:OUTPUTFREQUENCY(select50or60Hz)andFREQCONVERTER(selectenableordisable).SeeUPSSET-UPMENUoperation

section for instructions on setting these two options. When the UPS is running in FREQ CONVERTER mode, the INPUT LED will blink to

indicate that both AUTOMATIC BYPASS and MANUAL BYPASS operations are not available (since bypass would allow the wrong frequency

to pass through to connected equipment).

FREQUENCY CONVERTER MODE LEDs: INPUT (blinking), AC/DC,

DC/AC and OUTPUT LEDs on.

FREQ CONVERTER MODE LCD SCREEN: “FREQ CONVERTER”

and UPS load information

FREQ CONVERTER MODE LCD VIEWING OPTIONS:

When first entering FREQUENCY CONVERTER MODE, the LCD screen will display load information in percentage and kilowatt units. To

display additional information screens, tap the SCROLL DOWN (“v”) button repeatedly. Additional screens include: Kilowatt hour usage,

Kilowatt capacity remaining, Runtime-remaining in minutes, Battery voltage and charge percentage, Output voltage and frequency, Input

voltage and frequency, Load Power Factor and Load percentage plus kVA capacity.
