4. Operation
4-16
 This machine is so designed for safety that operator may not touch the output terminal during
operation. If you open the output terminal cover during operation with three-phase breaker switched
“ON”, the three-phase breaker will be “OFF” to cut power supply to the output terminal.
When starting operation, make sure that the output terminal cover is closed.
4.6.2 Meter and Indicator Lights while Operating
During normal operation, each indication of instruments is shown in the table below. Refer to the
table for daily checks.
Note; The values marked ※ vary with location of the voltage selector switch.

 Be sure to frequently check meters and indicators for
proper operation, or any machine water, oil, fuel leaks, etc.
 The above table gives standard values. They may vary
slightly depending on operating conditions and other
factors.
 In single-phase load operation, check the current of L1, L2,
and L3 phase with the ammeter, by turning the ammeter
change-over switch.
Each current should be balanced if unbalanced. Change
load connections so the current of L1, L2, and L3 is equally
balanced. Make sure that the current of each phase does
not exceed the rated one.
 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.
4.6.3 Panel light
 The instruments are provided with transmission type illuminators. Switch “ON” the panel light so
that they may light on.
 When illumination is not necessary, turn “OFF” the light. (If the machine is always operated with
the lamp switched “ON”, the lamp life can be shortened.)
