Should the configuration be other than that stated, instructions for calculating
current consumptions can be found in the relevant I/O manual. For the
AC 800M Controller, see Appendix B, Power Consumption.
Uninterruptable Power Supply
The SD83X series of power supply units comfortably handle the short power
interruptions (<20 milli seconds) that may occur normally within an industrial interruption
environment. Despite this, it is sometimes necessary to protect certain applications
against brief voltage failures by the installation of an Uninterruptable Power Supply
(UPS) device.
The AC 800M controller will shut down safely in the event of a power failure.
During down-time, the application memory and the system clock will be backed up
by the internal battery. In systems subject to long non-operational periods, it is
recommended that an external battery back-up unit be installed. When the power
supply is reconnected, the AC 800M Controller will re-start and run the application
as normal.
If the effects of unexpected shutdowns are not acceptable, it is highly recommended
that the AC 800M Controller be fully protected by connection to an Uninterruptable
Power Supply (UPS) source.
