If there are any possibilities of danger during work (especially during cleaning, maintenance, inspection,

Before entering the package for troubleshooting, setup, cleaning, or maintenance/inspection, always
apply lockout/tagout to the main motor and control power personally.
Shut off the power and perform lockout/tagout before entering the package. Clearly notify the workers
of the necessity of lockout/tagout.
It is assumed that workers do not perform lockout/tagout of the main motor and control power
before starting work because it is troublesome, and only turn "OFF" the main motor and control
power.
It is assumed that workers only turn off main motor and control power and do not lockout/tagout
the main motor and control power, because they think it is not important.
After checking that all the work is finished, the worker who applied lockout/tagout must release them.
