 Install a switch between the output terminal and the
load to switch on/off the load. Do not switch the load
on/off directly by the circuit-breaker of the generator.
It could cause damage to the circuit-breaker.
 Connect the connecting cable to the load so that the
output terminals should not touch each other.
4.3.1 Proper Connection of Three-phase Four-wire Type Terminal
 During operation, do not operate voltage selector switch. Voltage
selection during operation may cause abnormal voltage on the load
side to damage the load and may cause a fire.
 In addition it could cause damage to generator and automatic
voltage regulator (AVR).
 Be sure to shut off generator before using voltage selector switch.
 When voltage selection is completed, lock the voltage selector
switch in position to prevent anyone from operating it.
NOTE; When the voltage selector switch is in the single-phase 240/120V position, place the ammeter
change-over switch to the L1 or L3 position to read the output.
