Product Usage Instructions:
- Before performing any installation or maintenance tasks, ensure
that the power is switched off to avoid electrical hazards. - For installation and verification, it is recommended to seek
the assistance of an expert specialist. - Ensure that the fuse and switch disconnector used 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). - The DIN rail on which the contactor is fitted must be
earthed. - For LAN connectivity, connect the product’s LAN-TCP/IP
interface using an RJ-45 connector. It supports 10/100 BASE-T
Ethernet. - Follow the hardware connection instructions provided to
establish the LAN connection. - 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. - Mount the product on a DIN rail according to the DIN 43380 and
EN60715 standards. - 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. - Take into account the EMC disturbances and immunities
requirements specified in the manual. - Consider the environmental conditions, such as storage
temperature and relative humidity, to maintain optimal performance
and longevity of the product.

RESET
· Pressione breve, meno di 3 secondi –> Reboot del dispositivo. · Pressione di almeno 3 secondi –> I LED SPEED (verde) e FDX (giallo) iniziano a lampeggiare alternativamente. In questa fase, rilasciando il pulsantino, I valori di default della connessione vengono ripristinato e avviene un reboot. · A 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. · Pression courte, moins de 3 secondes –> Reboot du dispositif. · Pression de 3 secondes au moins –> le voyant SPEED (vert) et le voyant FDX (jaune) commencent à clignoter alternativement. Lors de cette phase, si petit bouton est relâché, les paramètres par défaut de la connexion sont restaurés et le dispositif effectue un reboot. · Presión breve, menos de 3 segundos –> El dispositivo ejecuta un reinicio. · Presión durante al menos 3 segundos –> El led SPEED (verde) y el led FDX (amarillo) empiezan a parpadear alternadamente. En esta fase, si se suelta el pulsador pequeño, se restablecen los parámetros predeterminados de la conexión y el dispositivo ejecuta el reinicio. · Kurzer Druck, weniger als 3 Sekunden –> Reboot der Vorrichtung. · Druck von mindestens 3 Sekunden –> Die LED SPEED (grün) und FDX (gelb) beginnen abwechselnd zu blinken. Durch Loslassen der Taste in dieser Phase werden die Standardwerte der Verbindung rückgesetzt und es erfolgt ein Reboot.
