Over Voltage, Under Voltage and Frequency Ranges
A–4
Table A-5 provides the over voltage, under voltage, over-frequency, and under-
frequency detection limits for the GT100. These detection limits have been
factory tested and deemed to be in compliance with UL 1741 Rev 2005 and
IEEE 1547 requirements for utility interaction.
