2Relay Contact-Closure Connection

Use the included DB9 cable (see 2a ) to connect spe- cialized electronic equipment to the relay contact-clo- sure port on your UPS System. See diagram 2b and chart below to determine signals carried by this port.

3EPO Port Connection

This optional feature is only for those applications which require connection to a facility’s Emergency Power Off (EPO) circuit. When the UPS is connected to this circuit, it enables emergency shutdown of the UPS’s inverter.

Using the cable provided, connect the EPO port of your UPS (see 3a ) to a user-supplied normally closed or normally open switch according to the circuit diagram (see 3b ). The EPO port is not a phone line surge sup- pressor; do not connect a phone line to this port.

4External Battery Connection

All UPS models come with a robust internal battery system; select models feature connectors (see 4a ) that accept optional external battery packs (sold separately from Tripp Lite) to provide additional runtime. Adding external batteries will increase recharge time as well as runtime. See battery pack owner’s manual for complete installation instructions. Make sure cables are fully inserted into their connectors. Small sparks may result during battery connection; this is normal. Do not connect or disconnect battery packs when the UPS is running on battery power.

If you connect any external batteries, set the Battery

Charge Level Switch (see 4b ) to the down position. This will increase your UPS’s charger output so the addi- tional batteries charge faster. Note: the switch to the right of the Battery Charge Level Switch is inactive and will not affect UPS operation regardless of its position.

CAUTION! DO NOT set the Battery Charge Level Switch to the down position without an external battery connected. There is a risk of damaging the UPS’s internal battery system.

Basic Operation

Buttons (Front Panel)

“ON/OFF/STANDBY” Button

When the UPS system is connected to a live AC utility power source, the UPS System will operate in one of three modes: ON, OFF or STANDBY. Refer to the chart below for UPS System operating characteristics within each mode.

	UPS Charges Battery	UPS Supplies Power to Outlets
Mode	(when utility is present)	(when utility is present or absent*)	UPS Displays LEDs
ON	Yes	Yes	Yes (variety of LEDs,
			depending on conditions)
OFF	No	No	No
STANDBY	Yes	No	Yes ("BATTERY CHARGE"
			LED only)

To place the UPS in the ON mode: First, have a qualified electrician connect the UPS System to a utility power source as outlined in the Quick Installation section. Once the utility power source is live, the UPS System will automati- cally enter STANDBY mode. Press and hold the “ON/OFF/STANDBY” button for one second** and then release it to switch the UPS System from STAND- BY mode to ON mode.

OPTIONAL: If the utility power source is not live, you can “cold-start” the

UPS System (i.e.: switch it directly from the OFF mode to the ON mode by supplying power for a limited time from its batteries*) by pressing and hold- ing the “ON/OFF/STANDBY” button for one second** and then releasing it.

To place the UPS in the OFF mode: With the UPS System in the ON mode and receiving utility power, press and hold the “ON/OFF/STANDBY” button for one second** and then release it to switch the UPS System from ON mode to STANDBY mode. Switch OFF the facility's circuit breaker which is supply- ing power to the circuit the UPS System is connected to.

* If batteries are fully charged. ** The alarm will beep once briefly after the interval has passed.

“MUTE/TEST” Button

To Silence (or “Mute”) UPS Alarms: briefly press and release the MUTE/TEST button.*

To Run a Self-Test: with your UPS connected to a live utility power source and turned ON, press and hold the MUTE/TEST button for two seconds.* Continue holding the button until the alarm beeps several times and the UPS performs a self test. See “Results of a Self-Test” below. Note: you can leave connected equip- ment on during a self-test. Your UPS, however, will not perform a self-test if the UPS is not turned on (see “ON/OFF/STANDBY” Button description).

Results of a Self-Test: the test will last approximately 10 seconds as the UPS switches to battery to test its load capacity and battery charge.

•If the “OUTPUTLOAD LEVEL” LED remains lit red and the alarm continues to sound after the test, the UPS’s outlets are overloaded. To clear the overload, unplug some of your equipment and run the self-test repeatedly until the “OUTPUT LOAD LEVEL” LED is no longer lit red and the alarm is no longer sounding.

CAUTION! Any overload that is not corrected by the user immediately following a self-test may cause the UPS to shut down and cease supplying output power in the event of a blackout or brownout.

•If the “BATTERY WARNING” LED remains lit and the alarm continues to sound after the test, the UPS batteries need to be recharged or replaced. Allow the UPS to recharge continuously for 12 hours, and repeat the self-test. If the LED remains lit, contact Tripp Lite for service. If your UPS requires battery replacement, visit www.tripplite.com to locate the specific Tripp Lite replacement battery for your UPS.

* The alarm will beep once briefly after the indicated interval has passed.
