2 Information on the explosion-protection devices
Danger
Explosion protection!
This warning marks information which applies if the device is used in a potentially explosive atmosphere.
Failure to comply with this information will result in loss of explosion protection and may lead to serious
injury or death.
Warning
Hazard resulting from improper use of the fans.
These operating instructions and the fan name plate describe how to use the EX fans safely.
♦Read the operating instructions completely and carefully.
♦If used in potentially explosive atmospheres, examine the name plate. Only use type PRF-EX fans.
Warning
Protective clothing must be worn in potentially explosive atmospheres to reduce the risks to employee
health.
♦Wear protective equipment during all work in the vicinity of the fan, details see 3.2 Personal protective
equipment, page 3.
♦Comply with the information on personal protective equipment displayed in the work area.
| 002

2| Important safety information
Warning
Regarding the choice of material, the EX fans fulfil the requirements of Standard DIN 14986 (Construction of
fans for use in potentially explosive atmospheres) as a result of specific protection measures in areas of
potential contact between rotating and stationary components (rotor/intake nozzle).
A safety clearance to the intake nozzle is guaranteed for the rotating part. The plant builder is responsible
for selecting the materials for the fixed peripheral parts for fan designs without protective grids. Only pairs
of materials according to Standard DIN EN 14986 are to be used.
Warning
The temperature class stated on the EX name plate (motor) must match the temperature class of the
combustible gas which may 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 loss of explosion protection.
♦In the event of recognisable transport damage, contact the manufacturer and do not put the device into
operation.
Warning
The effects of lightning strikes must be limited so that hazards are prevented. In addition to 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 resulting from excess voltage.
♦Carry out a risk analysis according to DIN VDE 0100, part 443, with a balance between protection and
consequences, taking the probability of the occurrence of excess voltage into account.
♦Protect all devices, protective systems and components by using suitable lightning and excess voltage
protection measures.
Warning
Ignition protection class „d“
If fans are controlled using motors with a "d" ignition protection class with a frequency converter, then
thermal protection via a PTC resistor in the motor is required.
3 Important safety information
Planners, plant builders and operators are responsible for the proper assembly and intended use.
♦Read the operating instructions completely and carefully.
♦Keep the operating instructions and other valid documents, such as the circuit diagram or motor instructions, with
the fan. They must always be available at the place of use.
♦Observe and respect local conditions, regulations and laws.
♦Abide by the system-related conditions and requirements of the system manufacturer or plant constructor.
♦Safety elements may not be dismantled, circumvented or deactivated.
♦Only use the fan in a awless condition.
♦Provide generally prescribed electrical and mechanical protective devices.
♦During installation, electrical connection, commissioning, troubleshooting, and maintenance, secure the location and
premises against unauthorised access.
♦Do not circumvent any safety components or put them out of action.
♦Before any work on the fan, test absence of voltage.
Even when the motor is stopped, dangerous voltages may be present on terminals.
♦Keep all the warning signs on the fan complete and in a legible condition.
♦The device is not to be used by persons (including children) with reduced physical, sensory or mental capabilities, or
lack of experience and knowledge, unless they have been given supervision or instruction.
♦Do not allow children to play with the device.

Safety information
Warning: Danger from falling fan or fan parts.
♦Check the surface before installation for load bearing capacity.
♦Consider all static and dynamic loads when selecting hoisting equipment and fastening components.
General safety information
♦Installation may only be carried out by adequately qualified persons, details see Table 1 Qualifications, page 3.
♦Abide by the system-related conditions and requirements of the system manufacturer or plant constructor.
♦Do not dismantle or circumvent safety elements, or put them out of function.
♦Move the rotor of the fan by hand before you install it in order to check that it moves freely.
♦Provide contact and intake protection and ensure safety distances according to DIN EN ISO13857 and DIN 24167-1.
♦Prevent the possibility of foreign bodies being drawn in.
♦To reduce transmission of vibration to the duct system, we recommend flexible connections from our accessory
range, see chapter Accessories.
♦The safety of the fans has to be ensured by protective devices according to DIN EN 294 (DIN EN ISO 12100-1) and
DIN 24167–1, the explosion protection measures necessary according to standard DIN EN 13980.
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.
Danger
Risk of ignition of a potentially explosive atmosphere!
♦Seal the system carefully.
♦Install accessory parts correctly.
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. To prevent an aluminothermic reaction, surface protection is required which at least fulfils the
cross-cut test classification 2 / DIN EN ISO 2409. 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.
