Terminal (Common): Feed with a jumped Phase wire from your main line or a dedicated control breaker.
Inside the panel, it was a mess. Wires were coiled like vipers, and most of the breakers were nondescript, their labels faded into illegibility. But in the center of the row, pristine and imposing, sat the unit he was looking for: the .
Complete Technical Guide and User Manual for the Merlin Gerin Multi 9 IC 2000 P Twilight Switch
For detailed wiring diagrams and step-by-step programming, you can download the official instruction sheet from RS Components or the updated Acti9 IC2000P+ manual from Schneider Electric . light sensitive switches IC200, IC2000, IC2000P - RS Online Merlin Gerin Multi 9 Ic 2000 P Manual
The Merlin Gerin Multi 9 IC 2000 P is a versatile and effective device for automatically managing outdoor lighting by combining a precision programmable timer with an adjustable twilight switch. This guide, derived from the official manual, should help you understand, install, program, and maintain the device. For any unresolved issues, consult a qualified electrician.
Once you secure the manual, here are the critical sections you should study first. (Based on similar Multi 9 auxiliary devices, expect the following data.)
Understanding the electrical thresholds of the IC 2000 P ensures safe installation and prevents premature component failure. 220–240V AC, 50/60 Hz Channels: 1 isolated output channel Contact Rating: 16A at 250V AC (resistive load / cos Brightness Adjustment Range: 2 to 2000 Lux Terminal (Common): Feed with a jumped Phase wire
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
Approximately 20 to 80 seconds (prevents flickering from passing clouds) Mounting Type: DIN Rail (35mm) Module Width: 5 modules (9mm steps) / 45mm total width Sensor Protection Rating: Typically IP65 (weatherproof) Switch Protection Rating: IP20 (indoor panel mounting) 2. Safety Precautions
Do you need assistance with a or a particular type of lamp load (e.g., LED, fluorescent)? But in the center of the row, pristine
| Problem | Likely Cause (per manual) | Solution | | :--- | :--- | :--- | | Device does not change state when breaker trips | Mechanical link missing or broken | Reinstall link; replace if damaged. | | Contact resistance too high (voltage drop) | Loose terminal or oxidized contact | Re-torque terminals; replace if contacts pitted. | | Auxiliary contacts chatter or bounce | Voltage/current below minimum rating | Check minimum load (e.g., 5V, 10mA). Use interface relay if needed. | | Overheating housing | Overload beyond rated current | Reduce load or use external power relay. | | No continuity in NO contact when actuated | Internal failure / welded contacts | Replace device — internal repair not permitted. |
Move the sensor out of the direct beam path of the controlled lighting. 6. Maintenance and Care
