Merlin Gerin Multi 9 Ic 2000: P Manual |link|
The unit is designed for TH35 DIN rail installation.
Installation should be carried out by a qualified electrician to ensure compliance with national and local electrical codes and to verify that upstream circuit protection is correctly sized.
Use the programming menu to define "OFF" periods (e.g., turning off at midnight even if it is still dark) to save energy.
As Merlin Gerin was integrated into Schneider Electric, this device is part of the legacy Multi 9 modular system, known for its extreme reliability. This comprehensive manual covers technical specifications, installation wiring, programming, and troubleshooting for the IC 2000 P (often designated under specific reference numbers like 15281 or similar variants).

Connect the included IP54-rated photocell, ensuring it is away from magnetic fields and in a location that accurately reflects ambient light levels.
Use the override button to switch between permanent ON, Permanent OFF, or Automatic operation. 5. Troubleshooting Common Issues
Equipped with a lithium battery providing a 5 to 10-year autonomy to maintain settings during power outages. The unit is designed for TH35 DIN rail installation
The remains a testament to the forward-thinking engineering of its era. Its ability to blend a twilight switch with a programmable timer created a powerful device for automated lighting control. While the Merlin Gerin name has been absorbed by Schneider Electric, understanding the Multi 9 IC 2000 P Manual is key to unlocking the full potential of this classic device.
Ensure the sensor window faces North or East to prevent direct blinding from midday sunlight. 3. Terminal Wiring Connections
The Merlin Gerin Multi 9 IC 2000 P is a programmable twilight switch designed to manage lighting circuits based on ambient light levels and pre-set time schedules. Originally manufactured by Merlin Gerin (now fully integrated into Schneider Electric), this device optimizes energy efficiency in commercial, industrial, and residential environments. As Merlin Gerin was integrated into Schneider Electric,
2 to 2000 Lux (split into multiple operational ranges)
Features a lithium battery backup with approximately 6 years of autonomy.
The factory fell silent. The hum of machinery was replaced by an eerie stillness. But in that silence, there was safety. The Ic 2000 P had fulfilled its duty, preventing a potentially catastrophic event.
