Installation Steps
Follow these steps for secure mounting of components onto the support rail:
-
Step 1: Component Insertion
Insert the Hilti MT-TL component into the slotted support rail. The component features a spring-loaded mechanism designed for easy engagement.
-
Step 2: Component Rotation
Rotate the inserted component approximately 60 degrees [rotation-symbol] to align and engage it correctly with the rail's internal profile.
-
Step 3: Component Sliding
Once the component is properly engaged, slide it along the support rail to the desired position.
Clearance and Gap Requirements
Adhering to specific clearance and gap requirements is crucial for optimal performance and safety:
- Maintain a minimum distance of 25 mm [distance-symbol] from the end of the support rail.
- Ensure a minimum gap of ≥ 5 mm [gap-symbol] between components or rail features.
- Another minimum gap requirement to observe is > 1 mm [gap-symbol].
- A further minimum gap requirement is ≥ 3 mm [gap-symbol].
Visual indicators in the original documentation show correct (✔️) and incorrect (❌) positioning relative to these clearances.
Component Dimensions (MT-TLB / MT-TLB 30)
The following table specifies the dimensions (t: thickness, L: length) for MT-TLB and MT-TLB 30 components, tailored to different material thicknesses:
| Material Thickness (t) | Component Type | Length (L) |
