It also has reinforced insulation between the main supply circuit and the communication circuit.

Product Usage Instructions

1. Before performing any installation or maintenance tasks, ensure that the power is switched off to avoid electrical hazards.
2. For installation and verification, it is recommended to seek the assistance of an expert specialist.
3. Ensure that the fuse and switch disconnector are used to comply with the standard IEC 62368-1. Use a certified cartridge fuse (5×20 mm) with a rated current of 125 mA and a maximum voltage of 250 Vac (e.g., Littelfuse 0218.125).
4. The DIN rail on which the contactor is fitted must be earthed.
5. For LAN connectivity, connect the product’s LAN-TCP/IP interface using an RJ-45 connector. It supports 10/100 BASE-T Ethernet.
6. Follow the hardware connection instructions provided to establish the LAN connection.
7. The product operates using TCP/IP protocol and supports application-level protocols such as HTTP and Modbus/TCP. It also utilizes SNTP, DHCP, and DNS protocols.
8. Mount the product on a DIN rail according to the DIN 43380 and EN60715 standards.
9. Ensure proper power supply by connecting the appropriate wires (0.5 mm2, acc. to IEC 60332-2-2 for smaller sections) to the specified operating voltage.
10. Take into account the EMC disturbances and immunities requirements specified in the manual.
11. Consider the environmental conditions, such as storage temperature and relative humidity, to maintain optimal performance and longevity of the product.

The installation must be performed and checked by an expert specialist. When working on the instrument, switch off the mains voltage! Fuse and switch disconnector in compliance with standard IEC 62368-1. Cartridge fuse 5×20 mm, certified according to standard IEC 60127-2.

• Rated current 125 mA.
• Maximum voltage 250 Vac.
• For example Littelfuse 0218.125
• The DIN rail on which the contactor is fit must be earthed.

One possible scheme of the system is described below. In the picture, the LAN- Gateway is connected to a PC. Instead, LAN-Gateway can be connected to a LAN network.

• Gateway: 192.168.1.1
• DHCP OFF

ACT LED
ACT LED (yellow): Blinking means LAN activity.

SPEED LED
The LED is ON if the LAN is 100 Mbit/s, it’s OFF if the LAN is 10 Mbit/s

FDX LED
The LED is ON if the LAN is full-duplex, it’s OFF if the LAN is half-duplex.

ON LED
ON LED (green): Power supply on

RESET

• short pushing, shorter than 3 seconds –> Device reboot.
• A push longer than 3 seconds –> SPEED (green) and FDX (yellow) LEDs start blinking alternatively.
• In this phase, by releasing the Reset button, the default network parameters are restored, and the device reboots.
