5.1 Prekawzjonijiet tas-Sigurtà

TWISSIJA: Installation involves high voltage. Ensure power is disconnected at the circuit breaker before performing any wiring. If you are unsure about electrical wiring, consult a qualified electrician. Improper installation can lead to electric shock, fire, or property damage.

5.2 Dijagramma tal-Wiring

The device features screw terminals for input power and four independent relay outputs. Each output has Normally Open (NO), Common (COM), and Normally Closed (NC) contacts.

• Qawwa tad-Dħul: Connect AC 85-250V to the 'Input 85-250V' terminals. Alternatively, for low-voltage applications or testing, connect a 5V Micro USB power supply to the Micro USB port.
• Load Connections (Channels K1-K4): Each channel (K1, K2, K3, K4) has three terminals:
• NC (Normalment Magħluq): Connected to COM when the relay is OFF.
• COM (Komuni): The common terminal for the relay.
• LE (Normalment Miftuħ): Connected to COM when the relay is ON.

Connect your appliance's power line to the COM terminal and the control line to either NO or NC, depending on whether you want the appliance to be ON or OFF when the relay is activated.
