[BACKLIGHT CHANGING PRECAUTIONS]
DANGER
z Before changing the backlight, always switch off the GOT power externally
in all phases (when the GOT is connected to the bus, the PLC CPU power
must also be switched off externally in all phases) and remove the GOT
main unit from the enclosure.
Not switching the power off in all phases may cause an electric shock.
Not removing the unit from the enclosure can cause injury due to a drop.

parts of the GOT.
Doing so can cause a failure or malfunction.
z When changing the backlight, always note the following.
(1) Wear gloves or fingerstalls before starting the replacement of the
backlight.
Not doing so can cause injury.
(2) Start changing the backlight more than 5 minutes after switching the
GOT power off.
Not doing so can cause a burn due to the heat of the backlight.
