Flat roof fitting and installation 5 Carrying out the installation 5.2.1 Installing racks Danger! Risk of death due to falling collectors! Unsecured collectors may fall from the flat roof due to the wind and present a danger to persons. ▶ Perform the following safety precautions according to the installation type. - Page 40 5 Flat roof fitting and installation ▶ Restore the tightness of the roof skin if Note necessary. For each rack, you will need four load plates: one pair each for the front and rear rack feet. ▶ Define the required rack clearances as described in the chapter "Defining rack clearances".
- Page 41 Flat roof fitting and installation 5 Danger! Risk of death due to inadequate fastening of the load weights onto the load plates! If the load weights are inadequately secured on the load plates, collectors could fall from the roof and cause life-threatening acci- dents.
