FAQ

• 1. Q: What is ABB 500PSM03A 1MRB150038R1?
      A: It is ABB AC800M rack power supply module, supplying DC power for all modules inside the control rack.

• 2. Q: Can it work in redundant configuration?
      A: Yes, two modules can be installed as redundant power supply to avoid shutdown caused by single power failure.

• 3. Q: Can it be hot swapped?
      A: Redundant configuration supports hot swap; cut off power supply before removing module for non-redundant rack.
