Multi 9 Ic 2000 P Manual | Merlin Gerin
Here is a quick cheat sheet based on the original manual's FAQ:
| Symptom | Likely Cause (per manual) | Solution | | :--- | :--- | :--- | | Trips immediately | 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). |

Mastering Your Lighting: A Guide to the Merlin Gerin Multi 9 IC 2000 P
Efficiency meets automation with the Merlin Gerin Multi 9 IC 2000 P, a versatile twilight switch that combines light sensitivity with a programmable time switch. Whether you are managing industrial lighting or optimizing your home’s energy use, this device ensures your lights are only on when truly needed—based on both ambient brightness and your specific schedule. Key Specifications at a Glance
Before diving into the manual settings, here are the technical highlights for the IC 2000 P:
Threshold Range: Adjustable from 2 to 2000 lux, allowing for fine-tuning from deep twilight to overcast daylight. Merlin Gerin Multi 9 Ic 2000 P Manual
Programmability: Features a 7-day weekly program with up to 42 memory settings.
Power Reserve: Equipped with a battery that offers a 6-year autonomy, ensuring your settings remain intact during power outages.
Load Capacity: Can directly control up to 10 A (at pf = 1) or be paired with a contactor for higher power loads. Installation & Wiring Basics
Proper installation is critical for the device to function correctly. Always ensure the main power is disconnected before starting.
Mounting: The unit is designed for TH35 DIN rail installation.
Sensor Placement: Connect the included IP54-rated photocell, ensuring it is away from magnetic fields and in a location that accurately reflects ambient light levels.
Wiring: Use tunnel terminals suitable for cables up to 6 mm². Ensure the connection between the sensor and the unit does not exceed 100 meters and is kept separate from 220V power lines to avoid interference. Programming Your IC 2000 P
The device offers three pre-set programs to get you started quickly: DAYPROG: Active from 7:00 AM to 8:00 PM.
NIGHTPROG: Active from 5:00 AM to 8:00 AM and 6:00 PM to 11:00 PM. EMPTYPROG: All functions off (useful for holiday modes).
To customize these, use the "+" and "-" keys to adjust the brightness threshold and the menu button to set the current time, date, and specific switching intervals. A built-in 80-second time delay prevents the lights from flickering due to temporary light changes, such as car headlights passing by. Where to Find the Full Manual

(now often branded under Schneider Electric's Acti 9 range as the IC2000P+) is a programmable twilight switch designed to control lighting or other electrical loads based on both light intensity and a weekly time schedule. Key Manuals and Documentation
Operating Instructions (Official): The most comprehensive guide is the Acti 9 IC2000P+ Operating Instructions, which covers wiring, initial setup, and advanced programming.
Technical Overview: For a summary of technical data, such as power consumption (0.8W standby) and switching capacity (10A–16A), refer to the IC2000P Technical Datasheet.
Installation Guide: A legacy Merlin Gerin IC2000 Installation Guide provides specific diagrams for mounting the external photocell and basic wiring. Core Functions and Features
Dual Control: It combines light-sensitive switching (adjustable from 2 to 2000 lux) with a 7-day (weekly) programmable timer. Here is a quick cheat sheet based on
Programming Capacity: Supports up to 56 switching operations and includes a lithium battery for a 5–10 year power reserve.
Override Options: Features manual and remote override capabilities, allowing you to force the load on or off regardless of the current program or light level.
Automatic Adjustments: Includes automatic winter/summer time changeover and a holiday schedule mode. Basic Programming Steps
Upon first power-up or after a reset, you must complete the following initial setup: Language: Select your preferred language (e.g., English). Date/Time: Set the current year, month, day, and time.
Light Threshold: Access the LIGHT menu to adjust the brightness threshold (lux) and set switching delays to prevent flickering from transient light (e.g., car headlights).
Schedule: Use the PROGRAM menu to define "On/Off" periods for specific days of the week. Wiring and Installation Tips
Photocell Placement: Mount the external sensor vertically using the provided IP54 housing. Do not place it near magnetic devices (transformers, contactors) or directly under the light it is controlling.
Cabling: Use separate conduits for photocell cables and 230V AC power conductors to avoid interference. Maximum photocell cable length is 100 meters.
High Power Loads: While it can directly control loads up to 1000W, use a contactor for higher power requirements or inductive loads to protect the internal relay.
