ATTENTION

1. Before using a Megger or a Withstand Voltage Tester remove the wires connecting to the AVR to

prevent high voltage damage to the regulator.

2. Improper setting of under-frequency protection could cause the output voltage of the unit to drop or

become unstable under with changes in load. Avoid making any changes to the U/F setting unless

necessary.

3. Turn off O/E in AVR when paralleling.

※Use only the replacement fuses specified in this user manual.
