METSEPM3255 power-meter installation: CT ratio, Modbus setup and digital points
Schneider Electric METSEPM3255 is a DIN-rail PowerLogic meter for three-phase electrical monitoring. Its readings depend on correct CT ratio, voltage wiring and communication setup. The shared power-metering collage is a category reference rather than an exact product photo of METSEPM3255.

Metering accuracy starts at wiring
Confirm each CT orientation, secondary rating, phase association and voltage connection before relying on METSEPM3255 data. Configure the CT ratio and system type to match the installed network. A plausible-looking reading can still be wrong if the phase sequence or transformer ratio is incorrect.
Integrate the data
Document METSEPM3255 RS485 address, baud rate, parity and the supervisory system's Modbus register map. Assign its digital inputs and outputs to the intended status or pulse functions. Verify trends and alarms against a known load after any replacement.
Commission and document
Use appropriate electrical isolation and CT-secondary handling procedures when installing METSEPM3255. Record nameplate, firmware, settings, network identifier and a baseline reading. A visually similar PM-series meter may have different communication or I/O features.
