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 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. Enclosures The AC 800M and S800 I/O units hold protection class IP20, with each unit being individually CE-marked. If a higher IP class is required, an additional enclosure is needed.

Normally the use of an additional enclosure will not influence the EMC characteristics of the controller. Enclosure Mounting When mounting the controller enclosure, it is important to provide certain minimum distances between the enclosure, the walls and the ceiling, in order to provide satisfactory ventilation. If the enclosure is provided with removable wall cladding, it is important to ensure that this is not removed from any enclosure adjacent to other enclosures containing equipment not belonging to the AC 800M Controller and its connected S800 I/O. ABB Cabinets As a suitable enclosure, ABB recommends the following two cabinets, both specially adapted for mounting the AC 800M Controller and S800 I/O. Both are sealed to protection class IP54 and can support the Controller and S800 I/O units with no requirement for additional cooling equipment: • RM550 – Floor-mounted cabinet • RE820 – Wall-mounted cabinet.
