Power and Control Sub-Rack
List 11: Power and Control Sub-Rack – HRMG (High Resistance Midpoint Grounded) Systems
Features
Provides the power and control sub-rack.
Provides two (2) rectifier mounting positions. A rectifier mounting position blank cover panel, P/N
553319, is furnished for each empty rectifier mounting position in the system.
Provides one (1) Model M820N ACU+ system controller. Provides the ACU+ IB2 interface board.
Provides a ground fault detection circuit. Provides a “System Shutdown” circuit.
Restrictions
Must be mounted in customer provided IT rack, unless ordered with List R1 or R2.
