the PE line of the power cable is at least 300 mm longer than the L1/L2/L3 lines
If the PE line of the power cable is loosened or disconnected, you may receive an
electric shock from leaked current.

When installing the power cable to the machine, make sure to connect the PE
line of the cable first and confirm its connection
If you come into contact with the machine when it is not grounded, you may receive
an electric shock that could result in severe injury or death.

Using a nonstandard power cable may cause an electric shock that could lead to a
serious injury or death. The power cable for this machine is prepared as an optional
accessory.
When connecting the power cable terminal to the power circuit breaker, be sure
to use a calibrated torque driver and tighten the screws of the breaker terminal
block with the specified torque
If the torque is not just enough, the connection between the power cable terminal and
breaker terminal block may heat up, which could cause a fire.

When the machine or floor is wet with water, do not touch the machine or wet
floor. Also, turn OFF the facility power source and lock it out with a padlock or the
like.
Also, never turn ON the facility power source until the machine and floor completely
dry. There is an electric hazard which could result in death or serious injury. Even
when the machine power is turned off, it will remain energized until the facility power
source is turned OFF.
