"Tag-out" is to prevent improper work of other people by attaching a tag plate that indicates
"work in progress", for example.
"Tag-out" is to place a tag that clearly indicates that it is prohibited to operate the energy cut-off
device while the (driving) energy source is being shut down. Such a marking tag is intended to give
a warning that the energy source cannot be operated, by clearly marking "Operation Prohibited",
"Startup Prohibited", "Do not open", etc., and it is not intended to actually operate the cut off
device.
Be sure to strictly observe the following instructions regarding the maintenance work on the electric
control:
The work must be performed by a qualified person who has been trained on the electric
control of the particular target system as well as on the potential risks inherent to electric
control and how to avoid the said risks, on top of the generally required knowledge on
electrical work.
Whenever servicing or inspecting electric machinery, be sure to cut off the motor main power
and control power, implement lock-out and tag-out procedures, and prevent any accidental
application of power during the work.
However, it should be noted that the system may be energized from other sources even if the
motor main power and control power are cut off, if power is supplied externally, i.e., not from the
refrigeration/cold storage unit that uses this product. In such a case, be sure to cut off the power
supply source, implement lock-out and tag-out procedures, and prevent any accidental application
of power during the work.
