9 Ic 2000 P Manual — Merlin Gerin Multi

The device features distinct terminal blocks for power input, sensor input, and load switching control.

Terminal 5 and 6 act as a standard single-pole switch. Connect a bridge wire from the Phase (Live) supply to Terminal 5. Connect Terminal 6 to the live side of your lighting load or to the coil terminal (A1) of an external contactor if controlling high-power lighting arrays. Programming and Settings

Proper installation is critical for the device to function correctly. Always ensure the main power is disconnected before starting.

High-voltage screw terminals for main power feed and load distribution. 3. Wiring and Installation Diagram Merlin Gerin Multi 9 Ic 2000 P Manual

Turn the potentiometer dial slowly until the status LED changes state. Leave the dial at this exact position. 5. Troubleshooting Matrix Potential Cause Remedial Action No power supply to the module.

If using the device to manage internal lighting zones near skylights, set the dial higher (between 200 and 500 Lux). Understanding the Hysteresis Delay

Always disconnect the power supply before installing or servicing the device. 3.1. Wiring Diagram The IC 2000 P has several connections on the base. Terminals 1-2: Supply Voltage (230V AC L/N). Terminals 4-5: Output Contact (Lighting Circuit). Terminals 6-7: Brightness Sensor Inputs. The device features distinct terminal blocks for power

Unlike modern electronic RCDs, the Multi 9 IC2000 P (depending on the exact vintage) may be sensitive to line/load reversal. The manual explicitly marks "Line" on top and "Load" on the bottom. Reversing these can destroy the device during a fault.

| Symptom | Likely Cause (per manual) | Solution | | :--- | :--- | :--- | | | Cumulative earth leakage > 30mA. | Use a clamp meter to find leaky appliance (heater, motor, old wiring). | | Test button fails to trip | Mechanical seizure or welded contacts. | Critical: Replace the unit. Do not rely on it. | | Lever won't reset | Persistent earth fault or internal damage. | Disconnect downstream wires. If lever resets, fault is in wiring. If not, RCD is dead. | | Unit runs hot | Loose terminal screws or overcurrent. | Torque to spec (2 Nm). Remember, this RCD has no thermal overload protection (needs an MCB in series). | Connect Terminal 6 to the live side of
