Installation

1. Choose the Installation Location: Install the SPD at the main distribution board or sub-panel near the power entry point.
2. Ensure Power is Off: Turn off the main circuit breaker and verify that the system is de-energized before proceeding.
3. Mount the Device: Secure the SPD onto the DIN rail inside the distribution cabinet.
4. Connect the Wires: Wire the SPD to the live (L), neutral (N), and grounding (PE) terminals as per the “2+0” circuit diagram.
5. Use Short, Thick Wires: Keep connections as short and straight as possible to reduce impedance and ensure optimal protection.
6. Verify Polarity and Tighten Connections: Double-check correct wiring and tighten all terminal screws securely.
7. Optional Remote Signaling: If available, connect the remote signaling terminals to a monitoring system or indicator panel.
8. Restore Power and Test: Turn the power back on and confirm that the SPD’s status indicator shows normal operation.
