(*) : - Select "IT Network" for computer loads. Select "Industrial" for other applications or when there exists and absolute need
for service continuity (with potential 10msec. interrupt) when Bypass AC source is not within set tolerances.
See table 3-5 for more details
(**) UPS will switch to Bypass AC Source if it is within the set tolerances.
(***) Input voltage must be equal to output voltage.
