2. Device description

The 5G-IIoT gateway is the universal platform to connect and measure data from industrial systems through 5G. The device comprises the Main unit, which can operate independently or in conjunction with other modules.

The Energy Meter module, also known as a 3-phase unit, measures the electrical data in a 3-phase supply network. The 3-phase voltages are measured via connection to VA, VB, VC, and VN. The currents are fed to IAP-IAN, IBP-IBN, ICP-ICN and INP-INN via current transformers. Based on these input signals, the 3-phase module calculates numerous values like voltages, currents, powers (active, reactive, and apparent), energies, power factors, phase shift angles, and frequencies.

It’s important to note that all three channels are independent, allowing for versatile usage. Each channel can be utilized for measuring individual loads, making it possible to monitor and measure consumption from separate consumers simultaneously.

2. Connectors

2.1 Push-in CAGE CLAMP WAGO requirements

For all units in our device we use WAGO cage clamp connectors. Please ensure that your wires meet the following requirements: Wire Gauge: Use wires within the recommended gauge range for optimal connection. Insulation Type: Choose wires with insulation compatible with the connector’s clamping mechanism and operating conditions. Stripping Length: Strip wire ends to the appropriate length for secure clamping. Wire Preparation: Straighten and clean wire ends before insertion to ensure proper contact. Refer to the table below for detailed specifications:

Solid conductor:	0.14 … 1.5 mm² / 28 … 16 AWG
Fine-stranded conductor:	0.14 … 1.5 mm² / 26 … 14 AWG
Fine-stranded conductor; with insulated ferrule:	0.25 … 0.75 mm²
Fine-stranded conductor; with uninsulated ferrule:	0.25 … 1.5 mm²
Strip length:	8 … 9 mm / 0.31 … 0.35 inches

2.2 New units connection

To integrate a new measurement unit simply follow the procedure demonstrated on the pictures bellow to assemble an interconnection bridge between the units. ⚠️ Safety Notice: Before adding a new unit, ensure that all wires are disconnected or have no voltage. Failure to do so may result in electrical hazards or damage to the device.
