11.1 Information about IBC AeroFix
Tightening torques of screw connections
The tightening torques of the screw connections used in the IBC AeroFix flat roof system should be
dimensioned in accordance with DIN ISO 3506. Due to the difficulty in determining the friction coefficients
in the external area, dimensioning in accordance with DIN ISO 3506 can prove difficult. We therefore
recommend the following tightening torques:
Screw connection Tightening torque
M8 (module clamp) 15 Nm
M8 (other) 10 Nm

11.2 Maintenance instructions
The IBC AeroFix mounting system is largely maintenance-free thanks to the materials used.
In addition to the electrical inspections prescribed for the entire PV system, we recommend an annual and
event-dependent (heavy storm, hail etc.) inspections of the mounting system into account the points of the
maintenance log..
Disassemly of the mounting system is carried out in the reverse order of assemly steps.
If it becomes necessary to clean the modules, this must be done without chemical cleaning products and
using only clear water.
The modules can easily be replaced by removing the module cabling and releasing the corresponding
module clamps. Please observe the relevant safety requirements when doing this.
