American Power Conversion 5000UXI user manual Initial Startup

Initial Startup

Charge the battery

The UPS charges its battery whenever it is connected to utility power. The battery will charge fully during the first four hours of normal operation. Do not expect full runtime during this initial charge period.

Connect Computer Interface Port (Optional)

Power management software and interface kits can be used with this UPS. Use only kits supplied or approved by the manufacturer. If used, connect the interface cable to the 9-pin computer interface port on the back panel of the UPS. Secure the connector’s screws to complete the connection.

Caution:

DO NOT use a standard serial interface cable to connect to the Computer Interface Port on the UPS. Standard

serial interface cables are incompatible with the UPS connector. Use the cable provided with your UPS.

Connect Ground Leads to TVSS Connector (Optional)

The UPS features a TVSS connector for connecting the ground lead on transient voltage surge-suppression (TVSS) devices such as telephone and network line protectors. The TVSS connector provides grounding through the UPS’s power cord ground conductor. To make a connection to the TVSS connector, loosen the screw and connect the surge suppression device’s ground lead. Tighten the screw to secure the lead.

Voltage Sensitivity

The UPS detects line voltage distortions such as spikes, notches, dips, and swells, as well as distortions caused by operation with inexpensive fuel-powered generators. By default, the UPS reacts to distortions by transferring to on- battery operation to protect the loads. Where power quality is poor, the UPS may frequently transfer to on-battery operation. If the loads can operate normally under such conditions, battery capacity and service life may be conserved by reducing the sensitivity of the UPS.

To reduce UPS sensitivity, press the configuration button on the rear panel. Use a pointed object such as a pen to press the button. Press it once to set the UPS’s sensitivity to reduced. Press it again to set the sensitivity to low. Press the button a third time to reset normal sensitivity.

When the UPS is set to normal sensitivity, the configuration LED is brightly lit. When it is set to reduced sensitivity, the LED is dimly lit.

When it is set to low sensitivity, the LED is off.

Low Battery Warning Interval

By default, the low battery warning occurs when there are approximately two minutes of on-battery run time remaining. This may not be enough time to gracefully shut down some protected computer systems.

To change the warning interval, press the rear panel configuration button while pressing and holding the front-panel on/test button.

2 min. When the LED is brightly lit, the low battery warning interval is approximately two minutes.

5 min. When the LED is dimly lit, the low battery warning interval is approximately five minutes. 7 min. When the LED is off, the low battery warning interval is approximately seven minutes.
