9.2 Preconditions
♦ Ensure that the fan and all its components are
undamaged.
♦ Ensure that there is enough space to install the fan.
♦ Protect against dust and moisture when installing.
♦ Ensure that the information on the name plates (fan
and motor) matches up with the operating conditions.
♦ Fit the fans in such a way that there is sufficient
access for troubleshooting, maintenance and repair.
♦ If harmful or hazardous products are transported,
check the general condition of the fan before opening.
Danger
Hazard of explosion of an ignition-capable atmosphere!
♦ Seal the system carefully.
♦ Install accessory parts correctly.
♦ The housing must be protected from impact by shock, if necessary using splinter protection (accessory)!
Aluminothermic Reaction - At high air speeds, in combination with aluminium, rust particles may lead to an
aluminothermic reaction which, in the worst case, can trigger the ignition of an explosive atmosphere.
Upstream or downstream components, or those which lie directly in the air flow, must not have any
unprotected aluminium or steel surfaces. Surface protection is required which at least fulfils the cross-cut
test classification 2 / DIN EN ISO 2409, in order to prevent an aluminothermic reaction. Steel with an
electro-galvanised or hot-dip galvanised surface is not critical. However, care must be taken that
appropriate protection is also applied to the cut edges.
Important
Damage to the bearings or other parts of the fan can occur.
♦ Do not place a duct bend directly before or after the fan!
♦ Ensure a smooth and constant air flow to the device. Ensure a free exhaust. See Fig. 1 Straight ducts ,
page 15.

9.3 Installation variations
The installation is possible in any mounting position.
9.4 Lightning protection device
♦ If the risk assessment shows that there is the risk of an atmospheric discharge, lightning protection measures must
be taken. For reasons of operational safety, provide for a suitable lightning protection system according to country
specific directives (e.g. DIN VDE 0185).
