Diagrama de cablejat:

Refer to the diagram below for proper wiring. Always ensure power is disconnected before making any electrical connections.

• Entrada d'alimentació: Connect the Live (L) wire to terminal 1 and the Neutral (N) wire to terminal 2. The timer requires AC220V power.
• Connexions de sortida: The timer has a single change-over switch output.
  • Terminal 4: Common (COM) output.
  • Terminal 3: Normally Open (NO) contact. This contact closes when the timer is ON.
  • Terminal 5: Normally Closed (NC) contact. This contact opens when the timer is ON.
• Connexió de càrrega: For loads up to 30A, you can directly connect your appliance to the appropriate output terminals (e.g., L to terminal 4, appliance to terminal 3, and appliance to N). For higher inductive loads or loads exceeding 30A, it is highly recommended to use an external contactor (as shown in Figure 3) to protect the timer's internal relay.
