13. UPS
The UPS (Uninterruptible Power Supply) protects the hard disk data (including Windows
and applications) from being damaged by power failure or power-off without shutdown.
CAUTION
■ Utilize the UPS only for protecting the data from damages caused by power
failure or power-off without shutdown. If the UPS is turned OFF over and over
intentionally while Windows is operating, the life cycle of UPS battery will be
shortened and the UPS may perform insufficiently.
■ Complete the shutdown of Windows within two minutes. If Windows is not shut
down within the battery backup time of the UPS, the data may be damaged.
The UPS consists of the battery and the ATX power inside the Controller. The UPS
provides backup power only for the 3.3V, 5V, and 12V power supplies that are necessary
to operate the CPU, hard disk, and the control board. The UPS does not back up the
power supply of Manipulator or Encoder Power Supply. Therefore, when a power failure
or power-off without shutdown occurs while the Manipulator is operating, an error such as
an encoder communication error occurs and the Manipulator makes an emergency stop.

sure the LCD panel is turned OFF and then turn OFF the power switch of the Controller.
