Diagrama de cablejat:
Refer to the diagram below for correct wiring connections. It is crucial to connect the Live (FireWire) and Neutral (Zero Line) correctly to the input terminals, and the load to the output terminals.

- Potència d'entrada (110 V CA):
- Connect the Live (FireWire) to terminal 1.
- Connect the Neutral (Zero Line) to terminal 2.
- Connexió de càrrega de sortida:
- Terminal 3: Common (C) for the switch output.
- Terminal 4: Normally Closed (NC) contact. The circuit is closed when the timer is OFF.
- Terminal 5: Normally Open (NO) contact. The circuit is closed when the timer is ON.
- For a typical switched load, connect one side of the load to the Live wire (or a jumper from terminal 1 to 3), and the other side of the load to terminal 5 (NO). The Neutral wire of the load should connect to the main Neutral line (terminal 2).
