Setup and Installation
Installation of the Gewiss 80003S GW20503 Bipolar Switch requires adherence to electrical safety standards. If you are not a qualified electrician, please consult one for installation.
Pre-installation Checks:
- Verify that the power supply to the circuit is completely disconnected at the main breaker.
- Confirm that the switch ratings (16A, AC/DC) match your application requirements.
- Ensure you have all necessary tools: insulated screwdrivers, wire strippers, voltage tester.
Wiring Instructions:
- With power off, carefully remove the existing switch or cover plate from the wall box.
- Identify the live (phase) and neutral wires from the power supply, and the corresponding wires leading to the load (e.g., light fixture). A bipolar switch interrupts both the live and neutral conductors.
- Connect the incoming live wire to one input terminal of the switch and the incoming neutral wire to the other input terminal.
- Connect the outgoing live wire to the corresponding output terminal and the outgoing neutral wire to its output terminal. Ensure all connections are secure and tight.
- For proper operation, ensure the switch is wired to interrupt both poles of the circuit.
Mounting:
- Carefully push the wired switch module into the wall box.
- Secure the switch to the wall box using the provided screws.
- Attach the decorative cover plate (if applicable) over the switch.
- Restore power at the main circuit breaker and test the switch functionality.
Operating Instructions
The Gewiss 80003S GW20503 Bipolar Switch operates with a simple rocker mechanism, providing ON-OFF-ON functionality.
- ON Position: Press the top or designated 'ON' part of the rocker to close the circuit, allowing power to flow to the connected load.
- OFF Position: Press the bottom or designated 'OFF' part of the rocker to open the circuit, interrupting power to the connected load.
- The switch is designed for reliable and consistent operation.
Maintenance
The Gewiss 80003S GW20503 Bipolar Switch requires minimal maintenance to ensure long-term performance.
- Cleaning: Periodically wipe the surface of the switch with a soft, dry cloth. For stubborn marks, a slightly damp cloth with mild soap can be used, ensuring no liquid enters the switch mechanism. Always disconnect power before cleaning.
- Inspection: Annually inspect the switch for any signs of damage, loose connections, or discoloration. If any issues are observed, disconnect power and consult a qualified electrician for inspection and repair or replacement.
- Do not use abrasive cleaners or solvents, as these can damage the plastic material.
