Merlin Gerin Multi 9 Ic 2000 P Manual — !free!
DIN rail mountable, occupying a compact modular width (typically 2 to 5 modules depending on the specific vintage/model variant)
Features a continuous liquid crystal display (LCD) showing the current time, day of the week, and switching status.
As part of Schneider Electric's brand harmonization, legacy Merlin Gerin Multi 9 items have transitioned over time. If you are servicing an old panel and find that the IC 2000 P needs a complete hardware replacement due to relay contact wear or sensor degradation, the direct modern equivalents can be found within the (such as the Acti9 IC2000 or IC100 series). These newer iterations maintain the identical DIN-rail form factor, making physical retrofitting seamless, though wire terminal locations should always be cross-referenced with the new device packaging.
This comprehensive technical guide serves as a manual for installers and system integrators to successfully wire, configure, and troubleshoot the IC 2000 P twilight switch. Technical Specifications
The primary objective of the Merlin Gerin Multi 9 IC 2000 P is to optimize energy consumption by ensuring that outdoor and indoor architectural lighting operates only when natural daylight drops below a specific, user-defined threshold. By combining an adjustable twilight switch with an integrated time-switch program (the "P" designation stands for Programmable), the IC 2000 P prevents unnecessary energy expenditure during late-night hours when illumination is not required, even if it remains dark outside.

Connect the included IP54-rated photocell, ensuring it is away from magnetic fields and in a location that accurately reflects ambient light levels.
The outdoor cell cover may be heavily covered in dirt, debris, or snow, mimicking night conditions. Clean the lens with a damp cloth.
The Merlin Gerin Multi 9 IC 2000 P is a high-performance twilight switch designed to manage lighting circuits based on ambient light levels. While Merlin Gerin has since been integrated into the Schneider Electric brand, these robust units remain a staple in many industrial and commercial electrical panels.
While it can directly control loads up to 1000W, use a contactor for higher power requirements or inductive loads to protect the internal relay. DIN rail mountable, occupying a compact modular width
The sensor detects light from the lamps it controls, or the switching delay is set too low.
Allows for forced "ON" or "OFF" states regardless of current sensor or time settings. RS-online.com Maintenance & Manual Access light sensitive switches IC200, IC2000, IC2000P
| 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). |
1 changeover contact (SPDT - Single Pole Double Throw). Switching Capacity: Resistive Load (cos φ = 1): 16 A at 250V AC. Inductive Load (cos φ = 0.6): 10 A at 250V AC. Incandescent/Halogen Lamps: Up to 2600 W. These newer iterations maintain the identical DIN-rail form
The is a programmable twilight switch that combines a light-sensitive sensor with a 7-day time switch for precise lighting control. This device is highly regarded for its reliability and professional-grade build, though many users find the manual and programming interface somewhat difficult to navigate . Product Overview & Key Features
The Multi 9 IC 2000 P functions by continuously measuring outdoor brightness via a remote photoelectric cell (sensor). When the ambient light drops below a user-defined threshold, the switch closes its output contact to turn on connected illumination (such as streetlights, security signs, or storefront displays). When dawn breaks and light rises above the threshold, the circuit opens. Key Technical Specifications 230V AC (+10% / -15%), 50/60 Hz
The is a robust, reliable, and widely used programmable time switch (often referred to as a digital time clock) designed for DIN rail mounting in electrical distribution boards. Engineered for precision, it allows users to automate lighting, heating, ventilation, and other electrical loads based on daily or weekly schedules.
