5-8 Connect UPS
The OMRON S8BA UPS protects the Panel PC from power failures, voltage variations and instantane-
ous voltage drops. Short power interruptions will be backed up by the UPS and the Panel PC will con-
tinue normal operation. The UPS signals the Panel PC when a power failure occurs and then the Pan-
el PC can shutdown normally without data loss. The Panel PC can automatically start up again when
the power is restored.
To connect the Panel PC to the OMRON S8BA UPS use one of the following two options:
• The USB connector and Power Attendant Lite Utility Software.
Refer to 5-8-1 Connect UPS Using the USB Connector on page 5-51 for details.
This is the preferred connection method.
• The I/O connector and a custom software program
Refer to 5-8-2 Connect UPS Using the I/O Connector on page 5-53 for details.
WARNING
The use of an uninterruptible power supply (UPS) allows normal operation to continue
even if a momentary power failure occurs, possibly resulting in the reception of an er-
roneous signal from an external device affected by the momentary power failure. Take
external fail-safe measures. Where necessary, monitor the power supply voltage on
the system for external devices and use it as an interlock condition.
Precautions for Safe Use
• Always use an uninterruptible power supply (UPS) to prevent data loss and other system file
integrity issues caused by unexpected power interruption.
• Use an Omron S8BA UPS with the correct revision number to prevent improper system shut-
down.
• Correctly perform wiring and setting, and ensure that the shutdown by the UPS can be exe-
cuted.
Additional Information
• The minimum power requirements of the UPS are dependent on the power consumption.
Refer to 4-1-3 Power Consumption Specifications on page 4-6 for power consumption details.
• Refer to the OMRON website for S8BA specifications or to the UPS S8BA User's Manual
(Cat. No. U702) for the UPS manual.
Note that the power consumption details determine the output current/capacity of your UPS.
