Warning
With a view to the choice of material, the EX fans fulfil the requirements of standard DIN 14986
(construction of fans for use in explosion-capable areas) as a result of specific protection measures in the
area of possible contact surfaces between rotating and stationary components (rotor/admission nozzle).
For the rotating part, a safety distance to the admission nozzle is guaranteed. The plant builder is
responsible for the selection of the materials for the fixed peripheral parts in fan constructions without
protective grids. Only pairs of materials according to standard DIN EN 14986 are to be used.
Warning
The statement of the temperature class on the EX name plate (motor) must match the temperature class of
the combustible gas which will possibly occur or the motor must have a higher temperature class.
Danger
Explosion protection
Transport damage or failure to comply with this information can lead to a loss of explosion protection.
♦ In the event of recognisable transport damage, do not put the device into operation and contact the
manufacturer.
Warning
The effects of lightning strikes must be limited to a hazard-free extent. Alongside protection against the
effects of „direct“ lightning strikes, this also includes protection against lightning strikes at a distance from
the building. The latter can lead to hazards as a result of excess voltages.
♦ Carry out a risk analysis according to DIN VDE 0100, part 443, containing a balance between protection
and consequences, taking the probability of the occurrence of excess voltages into account.
♦ Protect all devices, protective systems and components by suitable lightning and excess voltage
protection measures.

Repairs should preferably always be carried out by the manufacturer! Exceptions can be made for nonrelevant components such as terminal boxes, screwed cable connections, etc. These can also be dealt
with on-site by the operator's qualified staff (authorised personnel). Non-compliance will result in the
ATEX certification being revoked!
• For ATEX-certified products, the repair or replacement of fan components is expressly only permitted
after consultation with the manufacturer and only if the manufacturer's original parts are used!

13.3 Maintenance
Warranty claims can only be made if maintenance work is carried out correctly and written evidence thereof is
provided.
We recommend regular maintenance intervals to ensure continuous fan operation. These maintenance intervals are
specified in the “Activities” table below. In addition, the operator must carry out follow-up activities such as cleaning,
replacing defective components or other corrective measures. For traceability reasons, a maintenance plan must be
created which documents the work carried out. This must be created by the operator. If the operating conditions are
"extreme", the maintenance intervals must be reduced so that maintenance is carried out more frequently. Examples
of extreme operating conditions:
• Ambient temperature > 35 ºC or < 5 ºC, or temperature fluctuations > 20 K
• Use in an explosion capable area
