Alarms

USB PORT

The USB protocol is HID. The HID USB driver is standard in the Windows OS. Simply plug the USB cable into the UPS and the computer then follow the prompts on the screen.

RJ11 REPO (Remote Emergency Power Off) PORT

Connect one end of the RJ11 cable to the REPO port and the other end of the RJ11 cable to the EPO switch. In the AC or the Battery mode short pin4 to pin5 for approximately 0.5-seconds to shutdown the UPS. The UPS must be turned off and then back on again to restart the UPS.

POWER MONITORING SOFTWARE

The UPS comes with a Power Monitoring Software CD. See the software CD for the installation of the Power Monitoring Software.

OPTION SLOT

The option slot on the rear panel of the UPS is for option cards. Contact your local dealer for the available option cards.

ON BATTERY

When the UPS is operating on the batteries, the On-Battery LED will illuminate and the audible alarm will sound once every ten-seconds. The alarm will stop once the UPS returns to the AC normal mode.

LOW BATTERY WARNING

The UPS will sound two beeps every five-seconds when the battery reserve runs low. This condition will continue until AC returns or the UPS shuts down from battery exhaustion.

WEAK/BAD BATTERY

The UPS automatically tests the battery’s condition and will illuminate the Weak/ Bad Battery LED and sound the alarm. This alarm will be repeated until the batteries pass a self test. If the battery is weak, bad or disconnected, the Weak/Bad Battery LED will illuminate and the alarm will beep three times every five-minutes until the battery is reconnected or replaced. It is recommended that the UPS be allowed to charge overnight before performing a battery test to confirm a Weak/Bad Battery condition.

NOTE: If the UPS has a Weak/Bad Battery Alarm after reconnecting or replac- ing the batteries, the user must initiate a self test to clear the Weak/Bad Bat- tery Alarm. To initiate a self test see section 4 "SELF TEST".

OVERLOAD

When the amount of load attached to the UPS exceeds its power rating, the Overload LED will illuminate (AC mode only) and the UPS will sound a constant alarm (AC and Battery modes). This alarm will remain on until the excess load is removed or the UPS’s self protection circuit shuts the UPS down. If the UPS shuts down because of an Overload condition in the battery mode, the UPS must perform an Inverter function or a Self Test to clear the Overload Alarm.

UPS FAULT

When the UPS detects a hardware fault, the Fault LED will illuminate and the UPS will sound a constant alarm. The fault condition, in some instances, may be reset by turning the UPS off and then on.
