Main Intelligence Module (MIM)

The MIM is the onboard computer for the Power Array sys- tem. It gathers and processes data, including monitoring the condition 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 functioning, the main intelligence module can be replaced without placing the load at risk. The main intelligence module also communi- cates to an external battery frame (if present). The main intel- ligence module and the redundant intelligence module are fac- tory installed into custom racks that are built into the bay at the upper right of the frame.

Important: The MIM is always installed in the bottom rack, and the RIM is always installed in the top rack.

Redundant Intelligence Module (RIM)

The redundant intelligence module is a back-up 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 func- tioning 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.

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 utility voltage. When switched to the “on” position, power flows from the utility source into the Power Array. Under normal operating condi- tions, the input circuit breaker always remains in the “on” po- sition.

Fig 1-8Input Circuit Breaker & Maintenance Bypass Switch

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 utility power. When it is switched to the “off ” position, utility power flows into the Power Array, and conditioned power is delivered to the load equipment. The load equipment is unprotected when the main- tenance bypass switch is in the “on” position. Under normal operating conditions, the maintenace bypass switch always remains in the “off” position.
