ACCESSORY DESCRIPTIONS
ACU+ (Advanced Control Unit Plus) Controller, P/N 1M820DNA
Features
♦ Provides one (1) Model M820DNA, Spec. No. 1M820DNA system controller.
♦ Factory programmed with the configuration file required for the system
configuration ordered.
Note: For custom ACU+ configurations, contact Emerson.
Restrictions
Only one (1) controller per power system is required.
Mounts in the main bay (List 1) distribution cabinet.
Cannot be installed in a List 2, List 3, List 5, or List 6 supplemental bay.
Ordering Notes
1) Order one (1) ACU+ controller (P/N 1M820DNA) per power system.
2) Order optional ACU+ EIB (ACU+ Extended Interface Board) as required, P/N 548120.
