6. Installation
IMPORTANT: Disconnect all power before attempting any wiring. Incorrect wiring can cause damage to the device, property, or personal injury. If you are not comfortable with electrical wiring, please consult a qualified electrician.
The CN101S timer switch is designed for panel or wall mounting. Ensure the mounting location is dry, well-ventilated, and free from excessive heat or vibration.
Wiring Instructions (Example for 200-250VAC Model):
The wiring diagram below is an example for a 200-250VAC version of the CN101S. If your unit is a 12V, 24V, or 110V model, the wiring configuration will be different. Always refer to the specific wiring diagram printed on your unit or provided with your specific voltage model.
- Terminal 1 (LINE): Connect the live (phase) wire of your power supply to this terminal.
- Terminal 2 (NEUT INPUT): Connect the neutral wire of your power supply to this terminal.
- Terminal 3 (NEUT LOAD): Connect the neutral wire of the appliance you wish to control to this terminal. This terminal is typically internally connected to Terminal 2 (Neutral Input).
- Terminal 4 (LOAD): Connect the live (phase) wire of the appliance you wish to control to this terminal. This is the switched live output.
- Terminal 5 (LOAD): This terminal is typically used for a second switched live output or for specific wiring configurations. Consult your specific unit's diagram if using. For a single load, Terminal 4 is usually sufficient.
Ensure all connections are secure and insulated. After wiring, mount the timer switch using the provided screw holes.
