What is the level of protection of the Zenmuse L1?
The Zenmuse L1 has an IP54 rating under the IEC60529 standard. This means that it is protected against solid objects larger than 1 mm and against splashing water from all directions. However, the level of protection is not permanent and will decrease over time as the device wears.
To ensure the highest levels of protection:
- Before installation, make sure the interface and surface of the gimbal are dry;
- Before use, make sure the gimbal is firmly installed on the drone and the SD card protection cap is clean, free of foreign objects and closed;
- Before opening the SD card protection cap, wipe the surface of the drone.
