(2) Circuit Breaker 

This switch is for transmitting electrical power to the load side. Turn to ON position to 
output voltage to the output terminals. Output to the load side is cut off when there is a 
short circuit or overload on the load side. 

 

(3) 3-Phase Earth Leakage Relay 

When current leak occurs, it trips to stop power transmission to load. 

 

< Note > 

 Do not use this relay as the ON/OFF switch to the load. 

 

Voltage Regulator 

 
(1) Voltage Regulator 

This dial is for regulating voltage output by the generator.Turn the dial clockwise to 
increase the voltage and counterclockwise to decrease it. 

5-4.   Frequency change 

  CAUTION : PROPERTY DAMAGE 

 When changing the frequency, be sure to adjust the Frequency adjusut screw 

and change the Controller settings. 

 

Turn the Power Switch to ON position. 
Press the Stop Mode Button and "

" button together to enter the editor 

display. 

Press the "

" button or the "

"

" button. 

Press and hold the "

" button to save settings. 

 

< Note > 

 Check that no loads are connected before using the frequency selector switch. 

 Be sure to select "50Hz 400V" or "60Hz 440V". Contact distributor if you want to use 

"50Hz 200V" or "60Hz 220V".

 

 This switch is set to 50Hz when shipped from the factory.

 

5-5.  Fuel Piping Switch (3Way Fuel Valve) 

  CAUTION : FIRE

 

 

 Always make sure that the Power Switch is OFF position when working on 

piping. 

 Always be sure to wipe up any spilled fuel. 

 After working on the piping, check that there is no fuel leakage. 

Change the 3way fuel valve to switch to supply fuel from the external tank. In that case, 
the internal fuel tank is not used. 

 

(1) If using the internal fuel tank 

The 3

way fuel valve is turned to the “A” side when the generator is shipped from the 

factory.
