5.2.6 UPS Setup

The UPS Setup menu gives you access to various submenus. Select function choices

with the Select key. Access other submenus and confirm choices by pressing the Ok

key. The submenus are described below. All submenus are shown with the factory-

set function choice.

Note: The submenus are subject to changefor the latest changes refer to any

addendum or errata sheets included with this manual.

This screen shows the selected UPS self test mode. The

self test verifies the readiness of the UPS. This test helps

warn you of conditions that could cause unexpectedly

short run times.

ONSelf test runs immediately at start-up.

OFFSelf test function is disabled.

7 daySelf test is run automatically at startup and once

every 7 days.

14 daySelf test is run automatically at startup and once

every 14 days thereafter.

This screen shows the mains failure sensitivity setting. The

UPS can be set to automatically adapt to mains service

where extreme voltage distortion or severe rapid voltage

excursions occur. Such conditions may be caused by

inexpensive fuel generators, long branch circuits bur-

dened by heavy cyclic loads, nearby arc welding, or

heavy industry equipment.

AUTOUPS automatically adapts to mains service

quality. Select this to avoid frequent on-battery transfers

which could needlessly exercise the battery, shortening its

life. Normally, the UPS provides voltage regulation within

a narrow band. In response to rapid and frequent mains

voltage fluctuations, the UPS relaxes the regulation. This

relaxed regulation band remains within the bounds

recommended by telecommunications and computer

manufacturers. See the Specifications section for the

regulation ratings.
