Modbus bus cable Li2YCY (TP), RJ45 connector, 3 m HTG465H

Modbus bus cable with RJ45 connector and unshielded wire termination

This is a shielded Li2YCY (TP) cable designed for connecting h3+ switches to the agardio.manager system via the Modbus protocol. It is 3 m long and features an RJ45 connector on one end — the other end has unshielded wires intended for direct connection to terminals in a switch or distribution board.

The cable’s shielding provides immunity to electromagnetic interference — essential for data transmission in industrial environments where motors, converters, or other high‑current devices operate. The absence of a termination resistor means its function must be implemented at the device level (e.g., in an h3+ switch with an HTC310H/HTC320H module), offering flexibility in network configuration.

The cable also includes a protective earth (PE) conductor, which is required for proper operation of the communication system and installation safety — no additional grounding wire is needed. This simplifies assembly and eliminates the risk of wiring errors.

For the installer — simplicity and compatibility

No cutting or connector assembly is required. The RJ45 plug is standard, and the unshielded‑wire termination allows quick and safe connection to the switch terminals — without the need for extra components. The cable is specifically engineered for use with the h3+ series and HTC310H/HTC320H communication modules, ensuring full compatibility.

Installation only requires correctly wiring the conductors to the appropriate pins in the terminal — the online installation guide provides diagrams for all language versions. There is no need to worry about polarity: the RJ45 pinout is clearly defined, and the earth conductor is already integrated.

For the end user — stability and reliability

Thanks to the shielding and dedicated design, data from the switch (status, energy parameters, alarms) is transmitted without interference — even in the presence of nearby motors or variable‑frequency drives. This means the agardio.manager system receives accurate, real‑time information: power, voltage, current, harmonics, switch status — enabling effective diagnostics and energy‑usage optimization.

No additional grounding cabling is necessary — everything is ready out of the box, reducing installation errors and saving time.
