FAQs
Q: What is the recommended weight limit for the suspension rail?
To prevent safety risks, always make sure the total installed equipment weight does not beyond the rated capacity specified in the handbook.
Q: How should the rail be installed?
Install the rail horizontally between two sturdy support points (such as structural beams or wall studs).
Q: Can multiple AMU units be mounted on a single rail?
It is possible to attach more than one unit as long as the total weight does not surpass the rail’s maximum rated capability. Make sure that the distance between units permits adequate cable management and airflow.
Q: What tools are required for installation?
Make sure the supporting structure can withstand the weight and always take safety precautions.
Q: How do I ensure the rail is level and secure?
Before fastening the rail, line it using a spirit level. To ensure stability after installation, gently press down. Check the mounting points again and tighten the fasteners if there is any movement.
Q: Can the suspension rail be installed on drywall or other non-structural surfaces?
Mounting the rail only on plasterboard or other flimsy surfaces is not advised. To guarantee secure support, use structural studs, beams, or suitable reinforced anchors.
Q: Is it possible to adjust the height of mounted AMU units after installation?
Indeed, depending on the position of the mounting bracket, the design permits some vertical flexibility.
