(II) Mute Switch
Press and hold this button for 1 second, the UPS will mute the alarm after a short beep. Press and hold this button for another 1 second,
the UPS will restore the alarm function after a short beep.
(III) On-Line/Booster and Buck LED
When the unit is in the AC normal mode, this green LED indicator will always be on. It will be off when the unit is off. When the auto-
matic voltage regulator (AVR) is operating, this LED will blink.
(IV) On-Battery LED
The On-battery LED will be constantly illuminated and the UPS will beep once every 10 seconds until the unit reaches low battery warn-
ing or the unit returns to AC normal.
(V) Overload LED
When the unit senses an over-current condition on the output, this yellow LED will be lit and an alarm will sound continuously to indicate
an overload condition. If this condition happens, refer to the "Troubleshooting" section for recovery process.
(VI) Weak Battery/Internal Fault LED
When the battery goes bad, weak or becomes disconnected, this red LED will light indicating that the battery is not usable and must be
replaced. The alarm will sound 3 beeps every 1 minute if the battery is bad or disconnected. The alarm will sound 1 beep on every 1 sec-
ond if the battery is in low battery condition. The LED and alarm will remain in these states until the battery is replaced. Please follow this
procedure if this should happen:
STEP 1: Charge the UPS for approximately 8 hours.
STEP 2: Test the battery by turns the UPS OFF and back ON again.
STEP 3: If the LED lights and alarm sounds again, the battery must be replaced. Please contact your agent for more information.
This red LED will also light when the unit has an internal fault. This red LED will be off when all functions are normal.
(VII) Load LEDs
The four LEDs indicate the load percentage on the UPS output. Each LED indicates 25% of UPS capacity. When all four LEDs are lit,
the UPS is fully loaded.
(1) AC Input Socket
For 220V version, included is one standard IEC320 male socket.
(2) Input Circuit Breaker
The Circuit Breaker protects equipment plugged into the outlet against short circuits or system overload. The UPS will trip the breaker
when loads exceed the UPS's capacity. If the circuit breaker is tripped, unplug at least one piece of equipment from the outlet and reset
the breaker by pressing the button back into place.
If the AC input current is greater than the circuit breaker's regulated currency, the UPS's rear panel circuit breaker may tripped.
If the breaker is tripped, the UPS will attempt to operate the load by using its internal power source. If the UPS detects an overload con-
dition and the breaker is tripped, turn off the UPS and decide which equipment can be left unprotected without causing any damage. Find
the input circuit breaker on the rear panel and reset the breaker by pressing the button back into position. Then restart the UPS.
Note:
Generally the over-current accidents happen when there is an overload condition.
(3) Output Circuit Breakers
6 battery output sockets and 1 bypass output sockets equipped with a breaker respectively to protect against being over current on the
output. Circuit breaker is tripped when overload conditions happen.
(4) The additional socket outlet (Eurosocket).
The additional socket outlet of the general type. It is connected in parallel the basic target sockets.
(5) Battery Back and Surge Protection Outlets
IEC 320 female socket for 220V series. These provide instantaneous back-up power protection for your equipment and supplies tempo-
rary, uninterrupted, operation for your equipment during the utility power failure.
(6) RJ11/45 Phone/Network Surge Suppression
The RJ45/11 provides protection against the telephone and data line corruption. Plug either a 10 Base-T network cable or single tele-
phone line into UPS's «IN» jack. Plug the telephone line or the network cable from your equipment into UPS's «OUT» jack.
NOTE:
This connection is not required to operate the UPS.
(7) EPO Port
Emergency Power off (EPO) port enables user to turn off UPS immediately via a remote cable. This will allow connected loads to imme-
diately be de-energized from remote location, with out switching to battery operation.
(8) USB/RS-232 Port
This port can connect a USB or RS-232 cable to the computer. Using the software «Power Saving Plus II» to automatically saves files
and safely shuts down the computer if the utility power fails.
NOTE:
This connection is optional and not needed to use the UPS. The UPS works properly without a connection.
(9) SNMP Slot (Ready), SNMP card (Optional)
Built-in expansion slot for a SNMP CARD for network management/monitor.
NOTE:
The SNMP Card is optional. The UPS can operate properly without a SNMP Card.
