The FBT 2-String Profiline is a solar generator connection box designed for photovoltaic systems. This document provides essential guidelines for installation, operation, and safety. The device is rated IP65, ensuring protection against dust and water jets, and is constructed from glass-fiber reinforced polycarbonate.
Safety and Environmental Protection
To ensure safe operation and longevity of the device, observe the following precautions:
- Fire Protection: The housing meets class V-2 flammability standards. Perform a risk analysis of the installation site regarding fire hazards.
- UV Protection: While the housing is UV-resistant, avoid installation sites with permanent, intense direct UV radiation to extend the lifespan of components.
- Temperature: Ensure the device is installed in a location that prevents overheating. Maintain sufficient distance from heat sources and ensure air circulation.
- Condensation: The device is equipped with a pressure compensation element to prevent condensation buildup. Ensure this element is not obstructed.
- Chemicals: The housing is resistant to mineral oils and animal/vegetable fats, but avoid exposure to harmful chemicals.
Installation
Follow these guidelines for proper mounting:
- Choose an even, stable mounting surface.
- Install the device in a wind- and weather-protected area.
- Ensure all cable glands and connections are properly tightened and sealed.
- Do not install in locations prone to standing water or extreme mechanical stress.
