When it may not be suitable
This device is not intended for residential sub-metering where a simple DIN-rail mounted single-phase meter would suffice. It is also not suitable for environments requiring wireless connectivity, as it relies exclusively on a wired Ethernet connection for data transmission.
Key specifications
Phase type: 3-phase
Communication interface: Ethernet
Mounting: DIN-rail
Application: Industrial and commercial energy monitoring
How to use
The device should be installed on a standard DIN-rail within an electrical distribution board by a qualified electrician. Once mounted, the power lines must be connected according to the provided wiring diagram. After physical installation, the Ethernet cable should be connected to the device port, and the meter should be configured via the network interface to assign an IP address and integrate it into your monitoring software.
What to consider before purchase
Ensure your electrical panel has sufficient space for DIN-rail mounting.
Verify that your network infrastructure supports wired Ethernet connections at the installation site.
Confirm that your energy management software is compatible with the communication protocols supported by the meter.
