Note: The power for operating the EPO circuit is sourced from pin 1. This is an isolated 24 V which can source only a few milliamps. If the normally closed (NC) EPO configuration is used, the EPO switch or relay should be rated for "dry" circuit applications, the rating should be for low voltage and low current applications. This normally implies the contacts are gold-plated. Adhere to all national and local electrical codes when wiring the EPO. Wiring must be performed by a qualified electrician. The EPO interface is a Safety Extra Low Voltage (SELV) circuit. Connect the EPO interface only to other SELV circuits. The EPO interface monitors circuits that have no determined voltage potential. SELV circuits are controlled by a switch or relay properly isolated from utility power. To avoid damage to the UPS, do not connect the EPO interface to any circuit other than a SELV circuit. Use one of the following cable types to connect the UPS to the EPO switch. • CL2: Class 2 cable for general use. • CL2P: Plenum cable for use in ducts, plenums, and other spaces used for environmental air. • CL2R: Riser cable for use in a vertical run in a floor-to-floor shaft. • CLEX: Limited use cable for use in dwellings and for use in raceways. • Installation in Canada: Use only CSA certified, type ELC, (extra-low voltage control cable). • Installation in countries other than Canada and the USA: Use standard low-voltage cable in accordance with national and local regulations. Smart-UPS 750/1000/1500/2200/3000 VA 120/230 Vac Tower Troubleshooting Problem and Possible Cause Solution The UPS will not turn on or there is no output The unit has not been turned on. Press the ON button once to turn on the UPS. The UPS is not connected to utility Ensure that the power cable is securely connected to the unit and to the utility power. power supply. The input circuit breaker has tripped. Reduce the load to the UPS, disconnect nonessential equipment and reset the circuit breaker. The unit shows very low or no input Check the AC power supply to the UPS by plugging in a table lamp. If the utility voltage. light is very dim, check the utility voltage. The battery connector plug is not securely Ensure that all battery connections are secure. connected. There is an internal UPS fault. Do not attempt to use the UPS. Unplug the UPS and have it serviced immediately. The UPS is operating on battery, while connected to input utility power The input circuit breaker has tripped. Reduce the load to the UPS, disconnect nonessential equipment and reset the circuit breaker. There is very high, very low, or distorted Move the UPS to a different outlet on a different circuit. Test the input voltage input line voltage. with the utility voltage display. If acceptable to the connected equipment, reduce the UPS sensitivity. UPS is emitting an audible beeping sound The UPS is in normal operation. None. The UPS is protecting the connected equipment. UPS does not provide expected backup time The UPS battery is weak due to a recent Charge the battery. Batteries require recharging after extended outages and outage or is near the end of its service wear out faster when put into service often or when operated at elevated life. temperatures. If the battery is near the end of its service life, consider replacing the battery even if the replace battery indicator is not yet illuminated. The UPS is overloaded. Check the UPS load display. Unplug unnecessary equipment, such as printers. Display interface indicators flash sequentially The UPS has been shut down remotely None. The UPS will restart automatically when utility power returns. through software or an optional accessory card. The Fault indicator is lit and the UPS displays a fault message and emits a constant beeping sound Internal UPS fault. Do not attempt to use the UPS. Turn the UPS off and have it serviced immediately. All indicators are illuminated and the UPS is plugged into a wall outlet The UPS has shut down and the battery None. The UPS will return to normal operation when the power is restored has discharged from an extended outage. and the battery has a sufficient charge. Smart-UPS 750/1000/1500/2200/3000 VA 120/230 Vac Tower Problem and Possible Cause Solution The replace battery indicator is illuminated The battery has a weak charge. Allow the battery to recharge for at least four hours. Then, perform a self-test. If the problem persists after recharging, replace the battery. The replacement battery is not properly Ensure that the battery connector is securely connected. connected. The display interface has a Site Wiring Fault message Wiring faults detected include missing If the UPS indicates a site wiring fault, have a qualified electrician inspect the ground, hot-neutral, polarity reversal, building wiring. (Applicable for 120 V units only.) and overloaded neutral circuit.
