Physical Construction and Mounting Layout

The IEPMU01 features a rugged chassis construction designed for standard cabinet mounting. Its integrated bus bars distribute power evenly across all connected modules. You can mount this unit vertically or horizontally to suit cabinet space requirements. Furthermore, the design includes clear labeling for all termination points. This labeling simplifies initial installation and future troubleshooting efforts.

Power Distribution and Termination Capabilities

This power mounting unit accepts incoming field power through its main terminal block. It distributes this power to up to four power supply modules simultaneously. The IEPMU01 provides dedicated connections for AC input, DC output, and chassis grounding. You can terminate all field wiring without accessing the rear of the cabinet. The unit’s bus bar design minimizes voltage drop across multiple connected modules.

System Integration and Cabinet Organization

The module serves as the central power hub for Bailey system components. It organizes power supplies, filters, and distribution hardware in a single location. The IEPMU01 works alongside I/O termination units and processor racks for complete system layout. For similar industrial applications, static trip units and protective relays use comparable power distribution principles. However, this power mounting unit specifically addresses power organization requirements within the Bailey ecosystem. Facilities rely on it for clean cabinet layouts and simplified maintenance access.
