Ultra fast single-person deplyment
The ResIOT® X4S-A has been designed for extremely fast and straightforward installation, allowing single-person deployment without specialized tools and without the need to hold any weight during mounting or adjustment operations. The installation process consists of three simple steps:
- Mount the P-shaped bracket: secure the custom-designed P-shaped mounting bracket to a pole or wall. The bracket is fully designed, engineered, and manufactured in-house, ensuring robustness and perfect compatibility. It supports both pole mounting (for poles of various diameters) and wall mounting through dedicated holes for wall anchors.
- Attach the gateway and solar panel assembly: hang the gateway and solar panel body onto the slots located at the top of the bracket. The assembly pivots on a through-bolt inserted into the two fixing flanges, providing a stable and secure mechanical support while simplifying handling during installation.
- Adjust the solar panel tilt angle: set the optimal solar panel inclination according to the geographical location. The tilt angle is adjustable from 0° to 90°, with pre-defined 15° locking steps to ensure precise, reliable and repeatable positioning.
