Main Intelligence Module (MIM)
The MIM is the computer for the Power Array system. It gathers and processes data, including monitoring the condi- tion of each of the modules.
The PowerView functions as the user interface for the MIM, and is used to access data, and to configure the system. When a redundant intelligence module is installed and function- ing, the main intelligence module can be replaced without placing the load at risk. The main intelligence module also communicates with an external battery frame (if present). The main intelligence and the redundant intelligence mod- ule are factory installed in the upper right bay of the frame. Important: The MIM is always installed in the bottom rack, and the RIM is always installed in the top rack in this bay.

Redundant Intelligence Module (RIM)
The redundant intelligence module is a backup version of the main intelligence module. It provides redundancy in the event of a MIM failure or while a MIM is being replaced. If a functioning MIM is present, the RIM can be removed and replaced without placing the load at risk. The condition of the RIM can be determined with the PowerView display.
Input Circuit Breaker
The input circuit breaker protects the Power Array from ex- treme overloads. When switched to “stand by,” the Power Array is disconnected from incoming (mains) voltage. When switched to the “on” position, power flows from the mains power source into the Power Array. Under normal operating conditions, the input circuit breaker always remains in the “on” position.

Maintenance Bypass Switch
When switched to the “on” position, the maintenance bypass switch bypasses the Power Array and causes the load equip- ment to be powered directly from the mains power source. When it is switched to the “off” position, mains power flows into the Power Array, and conditioned power is delivered to the load equipment. The load equipment is unprotected when the maintenance bypass switch is in the “on” position. Under normal operating conditions, the maintenance bypass switch remains in the “off” position.
