Table 8-8: Emergency Voltage and Frequency Maximum
This test is test will set the voltage and frequency for a level defined by Table 8-7. The test will
last for 30 minutes. The test will be repeated using the voltage from Table 8-8 and frequency
from Table 9-7. The  key (backspace) will terminate the test at any time.
VOLT FREQ MAX
This test will set the voltage and frequency for a level defined by Table 8-8. The test will last for
30 minutes. The test will be repeated using the voltage from Table 9-7 and frequency from
Table 9-8. The  key (backspace) will terminate the test at any time.

Table 8-9: Emergency Voltage Unbalance
This test will change the output voltage for each phase from 115 volts to 115V + offset. Refer to
Table 8-9 for the offset value and the Frequency. The test will last 30 minutes. The test will be
repeated for a second Frequency if applicable. The  key (backspace) will terminate the test at
any time.
