FAQs
Install the unit in a suitable 42" H x 30" W x 12" D NEMA 12 enclosure to protect against dust and moisture. Use the included CT shorting blocks and the main fuse disconnect with four fused control disconnects to simplify wiring. Ensure 480V supply and 3-phase/4-wire configuration, and connect ModbusRTU/TCP, BACnet/IP, or WebUI for data access. Proper mounting reduces vibration-related wear and aligns with IEC 687 safety practices.
The PXM8051A1BA-2B4-A carries CE Marking and compliance with ANSI/IEEE Std C12.20 (0.2% accuracy), ANSI/IEEE Std C62.41, and IEC 687 (0.2% accuracy). These certifications ensure measurement accuracy, electrical safety, and reliability under surge and transient conditions, which supports compliant energy billing and safer operation in industrial environments.
The meter supports ModbusRTU, ModbusTCP, BACnet/IP, and WebUI, enabling seamless integration with common industrial automation stacks. For integration, configure Modbus addresses in the device and map energy data to your SCADA or MES system. The WebUI provides a convenient, browser-based monitoring interface, reducing the need for separate software installations.
Yes, the meter is rated for 480Vac in 3-phase/4-wire configurations, with a main fuse disconnect and four fused control power disconnects for robust protection. The four CT shorting blocks simplify current measurement connections, while the NEMA 12 enclosure protects against dust and moisture in typical industrial settings, supporting reliable, continuous operation.
The meter provides 0.2% accuracy per ANSI/IEEE C12.20 and IEC 687, ensuring precise energy measurements for billing, demand calculations, and energy management. This accuracy reduces revenue leakage, supports better demand-side optimization, and shortens payback periods for energy efficiency projects across manufacturing floors and data centers.
