The Merlin Gerin Multi 9 IC 2000 P is a high-performance, DIN-rail mounted twilight switch designed to optimize outdoor and indoor lighting systems. By measuring ambient light levels via an external photoelectric cell (sensor), the IC 2000 P automatically switches electrical circuits on at dusk and off at dawn.
Standard setting for street lighting and shop signage at dusk.
A: The manual allows it as a “load break switch” (rated for making and breaking load current up to 80A). However, it does not provide short-circuit protection. You must have a fuse or MCB upstream. Merlin Gerin Multi 9 Ic 2000 P Manual
: Install the supplied outdoor wall-mounted sensor away from artificial light sources (like streetlights) that might trick the system. Wiring Connections : Terminals L & N : Main power supply (220-240V AC).
Adjustable from 2 to 2000 lux , allowing for fine-tuning from deep twilight to overcast daylight.
Comply with national wiring regulations (e.g., IEE, NEC, or local equivalents). 3. Installation and Wiring Diagram
Increase the lux threshold or check the sensor placement. technical data
The Lux threshold may be set too low (e.g., 2 Lux). Turn the dial up toward 100 Lux to see if the relay engages.
Standard twilight operation relying on the sensor and Lux dial.

The manual serves as a comprehensive guide, ensuring that you can maximize the potential of this versatile protection device. 200 lux
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.
Approximately 20–80 seconds (built-in hysteresis to prevent flickering caused by car headlights or clouds) Module Width: 5 modules of 9mm (45mm total width) Power Consumption: Approximately 6 VA Sensor Protection Rating: IP65 (weatherproof outdoor cell)
If the system fails to operate as expected, consult the following diagnostic matrix: Lights Do Not Turn On at Night
Ensure the sensor window faces North or East to prevent direct blinding from midday sunlight. 3. Terminal Wiring Connections
Disclaimer: Electrical work is dangerous. Always isolate the supply and verify dead before touching terminals. When in doubt, call a licensed electrician.
