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.
