NOTE: Interrupted Transfer to Bypass Source:
If the bypass source is beyond the conditions stated below, the UPS will make an interrupted transfer (not more
than 100 msec. in duration).
1. Bypass voltage greater than +15%, —15% from the UPS rated output voltage.
2. Bypass frequency greater than ±2 Hz from the UPS rated output frequency.
