13.1. Information about IBC AeroFix
Tightening torques of screw connections
The tightening torques of the screw connections used in the IBC AeroFix / AeroFlat 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
M10 30 Nm

13.2. Maintenance instructions
In addition to the electrical inspections prescribed for the entire PV system, it must be carried out an
annual and event-dependent (heavy storm, hail etc.) inspections of the mounting system into account the
points of the maintenance log.
In the maintenance log
“not ok” points must be repaired to avoid further damage.
Mechanical connections, e.g. the module clamps must be checkedfor firm seating and tightening torque
and tightened if necessary. Building protection mats can slip and have to be brought back into position.
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.
