4. TCU1.2 MOUNTING INTERFACE

The TCU 1.2 is mounted on a plane surface fixed on the vehicle frame. The TCU 1.2 has 3

mounting points equipped with silent blocks. The TCU 1.2 must be fixed on a support (available

on demand). This support (“TCU 1.2 interface”, also called “Bracket base”) is defined in the

appendix.

5. TCU 1.2 MOUNTING RECOMMENDATIONS

Screws (not provided by LDL) must be tightened @ 4,5 Nm +/-0,5 Nm. It's recommended to use

an elastic washer (Belleville type) between screw head and silent block with spacer. Stainless

steel is recommended.

M6 bolts are recommended, the screw for a fixation on a base plate fixation in thickness 1,5mm

must have a length equal or higher than 20mm.

NOTA BENE : The usage of a different bracket; without LDL written

approval; would void the warranty of the TCU 1.2.
