5.0 Operation

5.6.4 Operation customizing

You may configure many UPS operations for specific applications. To use the customizing features of the UPS, you must set all option switches to the on ( I ) position. The functions ordinarily controlled by the switches are duplicated in the UPS monitoring software. Once any of the option switches are returned to the off ( O ) position, functionality of the option switches is restored.

■Battery test operation

You can set the battery test to automatically run at startup, at startup and once every 7 days, at startup and once every 14 days, or never. The default setting is at startup and every 14 days.

■Transfer voltage

You can configure the UPS’s upper and lower transfer voltages over a wide range (see Sec. 9.2.)

■On-battery output voltage (220/230/240 Vac version only)

You may set the UPS’s on-battery output voltage to a nominal 220, 225, 230 or 240 Vac. The default setting is 225 Vac.

■Utility failure sensitivity

You may configure the UPS’s sensitivity to line-voltage distortions to allow use of the UPS in different electrical environments. You may choose high, medium, or low sensitivity settings. The high setting provides the best protection from all utility voltage distortions. The medium setting is intended for use where rapid low-amplitude line voltage fluctuations occur frequently as the result of motor load switching in air conditioners, eleva- tors, etc. The low setting is intended for use when the UPS is operated from an inexpensive fuel powered generator. The default setting is high.

■Low battery warning interval

The UPS’s low battery warning may be set to activate 2, 5, 7 or 10 minutes before shutdown. The default is 2 minutes.
