5-8 Connect UPS
The OMRON S8BA UPS protects the IPC from power failures, voltage variations and instantaneous
voltage drops. Short power interruptions will be backed up by the UPS and the IPC will continue nor-
mal operation. The UPS signals the IPC when a power failure occurs and then the IPC can shutdown
normally without data loss. The IPC can automatically start up again when the power is restored.
To connect the IPC 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 5-44 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 5-46 for details.
WARNING
The use of an uninterruptible power supply (UPS) allows normal opera-
tion to continue even if a momentary power failure occurs, possibly re-
sulting in the reception of an erroneous signal from an external device
affected by the momentary power failure. Take external fail-safe meas-
ures. Where necessary, monitor the power supply voltage on the sys-
tem 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 4-4 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.
