Zero Energy State

"Zero Energy State" is to maintain the condition to
inhibit unexpected energy releases or inputs during
maintenance work. In other words, Zero Energy
State is to prevent unexpected output or input of
energy when the engine is not used, even if the
potential energy is not zero.
• You must know how to set the engine
to Zero Energy State.
• When setting the generator to Zero
Energy State, refer to the
corresponding manual of the generator.

Working Procedure in
Dangerous Areas

Works in Dangerous Areas

When you need to enter a dangerous area, for
example, to solve a problem that has occurred
during operation, follow the procedure shown
below.
■ Works that require Lockout/tagout
• When you conduct a work which can
not be done for a short time, for
example, when replacing a part,
conduct lockout/tagout for ensuring
safety.
Operate the stop switch of the
1
generator "Starting and Stopping
Devices Installed during
Manufacturing the Generator" (→
Page 87) to turn off the engine.
Lock the starting switch of the
2
generator "Starting and Stopping
Devices Installed during
Manufacturing the Generator" (→
Page 87) with a key and hang a tag,
as necessary.
• A tag must be hanged, as necessary,
by considering the number of the
operators, difficulties to check the
presence of each other, or the
working times.
Conduct the works.
