Configuration Program

8.6.3Frequency Selection

The UPS is normally designed for 50Hz or 60Hz operation. The factory default corresponds to the model. All models are capable of being used as 50Hz or 60Hz systems. The UPS will Auto-sense the utility frequency when first plugged in and set the nominal frequency to match. Therefore, for all nor- mal use the Auto Sense button should be selected.

Some special applications require that the UPS be used as a frequency converter. Frequency Con- verter 50Hz mode will provide 50Hz UPS output from 60Hz commercial power. Frequency converter 60Hz mode will provide 50Hz UPS output from 60Hz commercial power.

Note that frequency converter operation disables the Bypass. If, for any reason, the UPS inverter is unable to power the load, the alternate bypass to utility power will not be available and power will be removed from any load.

8.7Options Tab

Computer users may choose to use versatile computer shutdown software that communi- cates with the UPS via a serial communication cable. The Options Tab should not be used to modify the UPS functions for such applica- tions.

For some industrial applications and special computer applications, the UPS may be moni- tored and controlled using external voltages and relay contact signals. The Options tab expands the UPS versatility for such applica- tions.

Refer to your UPS manual for a description of the nine-pin communication connector on the rear of the UPS. Pin 6 of the nine-pin commu- nication connector is used for “Any Mode Shut- down” of the UPS output. This control input may be used in special applications to disable the UPS output power—both Inverter and Bypass.

The Options Tab allows the behavior of the Any Mode Shutdown feature to be modified.

When the program opens, or the Refresh but- ton is pressed, the UPS setting is read by the configuration program and displayed.

! WARNING

Auto-Enable Output

Note that when this option is selected and the UPS output is disabled using Pin 6, the UPS output can turn on automatically and without warning if the Pin 6 connection is changed.

! WARNING

Pin 6 Logic

DO NOT CHANGE THIS OPTION from the factory default setting unless you are ready to install a normally closed connection between Pins 5 & 6. This connection must be maintained to use the UPS or to use the configuration program again, including the ability to change the UPS setting back to the default setting using the configuration program via a serial communication link.
