7. Installation and Wiring
7.1 Installation Steps
- Power Disconnection: Before starting, ensure the main power supply to the circuit is completely turned off at the service panel.
- Mounting: Mount the TOB9-63M onto a standard 35mm DIN rail within an appropriate electrical enclosure. Ensure it is securely clipped into place.
- Wiring: Refer to the wiring diagram below. Connect the incoming neutral (N) and live (L) wires to the top terminals marked 'N Power' and 'L Power' respectively. Connect the outgoing neutral (N) and live (L) wires to the bottom terminals marked 'N Load' and 'L Load'.
- Secure Connections: Tighten all screw terminals firmly to prevent loose connections, which can cause overheating or intermittent operation.
- Verify: Double-check all wiring connections for correctness and security.
- Restore Power: Once installation is complete and verified, restore power to the circuit.
7.2 Wiring Diagram
The device is a 1P+N (Single Pole + Neutral) circuit breaker. The 'N' terminal is for the Neutral wire, and the 'L' terminal is for the Live (Phase) wire. Ensure correct polarity.
- Top Terminals: Input Power (N, L)
- Bottom Terminals: Output Load (N, L)
