Figure 2: Front View of the Symmetra RM
Power Module(s) : The Symmetra RM can support between one and four power modules. Each module
provides 2 kVA/1.4 KW power.
Redundant Intelligence Module : The redundant intelligence module (RIM) is a backup version of the main
intelligence module(MIM). It provides redundancy in the event of a MIM failure or while a MIM is being
replaced.
Main Intelligence Module : The main intelligence module (MIM) is the “computer” of the Symmetra RM.
It gathers and processes data, including monitoring the condition of each of the modules.
Battery Module(s) : Each battery module contains multiple batteries housed in the enclosure. The
Symmetra RM can house up to six battery modules (three on the right and three in the lower bays on the left).
System Enable Switch : The system enable switch regulates power to the intelligence modules. It does not
power the load. When the switch is in the On position, the Symmetra RM enters the load-disconnect operating
mode. When the switch is in the Stand By position, the intelligence modules are disconnected from the utility
(mains) voltage.
The load is not powered until the Power the Load command is entered into the PowerView RM
interface.
Mounting Rails : The attached mounting rails (one on either side) support the Symmetra RM when it is
mounted in a rack.
Mounting Bracket : The mounting bracket allows you to secure the Symmetra RM in the rack.
PowerView RM : The PowerView RM is the primary user interface for the Symmetra RM.
