Select the meter and communication module as one ordered configuration
- This reviewed meter is a three-phase four-wire CT-connected design. It is not a single-phase, direct-connected or DIN-rail meter.
- Confirm the primary CT ratio and the 5 A secondary circuit before wiring or register mapping is released.
- RS485 and infrared are documented interfaces; PLC, RF, 2G, 3G and 4G are plug-in module options, not simultaneous standard equipment.
