4.1 Gambarajah Pendawaian

Imej 3: Wiring diagrams showing direct connection (left) and connection with an AC contactor (right). The direct connection illustrates neutral and live wire inputs and load output. The AC contactor diagram shows 220V power input and output to the load device.
Direct Wiring: Connect the neutral and live wires to the designated input terminals (L and N). Connect the load to the output terminals (typically 3 and 4 for normally open, or 3 and 5 for normally closed, as indicated on the device). Refer to the diagram on the device for exact terminal numbering.
Wiring with AC Contactor: For higher loads, connect the timer to control an AC contactor. The timer's output will switch the coil of the contactor, which in turn controls the main power to the load. This setup is shown on the right side of Image 3.
