What are the risks involved in using same power supply for powering system and field in an AC800M HI based system?
As per the safety manual for AC800M HI (3BNP004865-511 Page 71), It is strongly recommended to use separate power supplies for powering System Units and powering Field Equipment. We have a requirement for supplying an AC800M HI based system with one cluster (2 DIs and 2DOs). And we have a space restriction to include separate power supplies for system and field. I would like to know the risks involved in using common power supplies for system and field. Also would like to know if anybody used this configuration in any of the project.
