Failure to comply with this warning may lead to
moderate injuries.
Important
Hazard with risk of damage to objects
Failure to comply with this warning will lead to
damage to objects.

2 Information on the explosion-protection devices
Danger
Explosion protection!
This warning marks information applying in use of the device in an explosion-capable area. Failure to
comply with these contents and instructions leads to loss of explosion protection and can lead to serious
injuries and death.
Warning
Hazard as a result of improper use of the fans.
These operating instructions and the name plate of the fan describe safe use of the EX fans.
♦ Read the operating instructions completely and carefully.
♦ When used in explosion-capable areas, examine the name plate. Only use type PRF-EX fans.
Warning
In order to rule out risks for the employees‘ health, protective clothing must be worn in explosioncapable
areas.
♦ Wear protective equipment during all work in the vicinity of the fan, details see 3.2 Personal protective
equipment, page 7.
♦ Pay attention to the information shown in the work area concerning personal protective equipment.
| 002
| Important safety information
6
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.
GB
Warning
Ignition protection class „d“
If fans are controlled with engines of the „d“ ignition protection class with frequency converter, thermal
protection by a PTC resistor in the motor is necessary.
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.
♦ 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.
♦ 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.
3.1 Personnel
The fan may only be used by qualified, instructed and trained personnel. The persons must know the relevant safety directives in order to recognise and to avoid risks. The individual activities and qualifications can be found in Table 1 Qual-
ifications, page 7.

3.2 Personal protective equipment
Wear protective equipment during all work in the vicinity of the fan.
• protective working clothes
• protective working shoes
• protective working gloves
• helmet
• goggles
• hearing protection
3.3 5 rules of electrical safety
1. Disconnect (disconnection of
the electrical system from
live components at all
terminals)
2. Prevent reactivation
3. Test absence of voltage
4. Ground and short-circuit
5. Cover or restrict adjacent live parts
4 Warranty
For the assertion of warranty claims, the products must be correctly connected and operated, and used in accordance
with the data sheets. Further prerequisites are a completed maintenance plan with no gaps and a commissioning report. Systemair will require these in the case of a warranty claim. The commissioning report is a component of this
document. The maintenance plan must be created by the operator, see section 13.3 Maintenance, page 20.
5 Delivery, transport, storage
5.1 Safety information
Warning: Risk from rotating fan blades
♦ Prevent access by unauthorised persons by safety personnel or access protection.
Warning: Suspended loads
♦ Wear protective equipment during all work in the vicinity of the fan, details see 3.2 Personal protective equipment,
page 7.
♦ Do not walk under suspended loads.
♦ Make sure that there is nobody under a suspended load.
5.2 Delivery
Each fan leaves our plant in an electrically and mechanically proper condition. We recommend transporting the fan to
the installation site in the original packaging.

Checking delivery
♦ Check the packaging and the fan for transport damage. Any findings should be noted on the cargo manifest.
♦ Check completeness of the delivery.
Unpacking
Warning
When opening the transport packaging, there is a risk of damage from sharp edges, nails, staples,
splinters etc.
♦ Unpack the fan carefully.
♦ Check the fan for obvious transport damage.
♦ Only remove the packaging shortly before assembly.
♦ Wear protective equipment during all work in the vicinity of the fan, details see 3.2 Personal protective
equipment, page 7.
5.3 Transport

♦ Never transport the fan by the connecting wire, terminal box, impeller, protection grille, inlet cone or silencer.
♦ In open transport, please make sure that no water can penetrate into the motor or other sensitive parts.
♦ We recommend transporting the fan to the installation site in the original packaging.
GB
Caution: If transported without care during loading and unloading, the fan may be damaged.
♦ Load and unload the fan carefully.
♦ Use hoisting equipment that is suitable for the weight to be hoisted.
♦ Observe the transportation arrows on the packaging.
♦ Use the fan packaging exclusively as transport protection and not as a lifting aid.
5.4 Storage
♦ Store the fan in the original packaging in a dry, dust-free location protected against weather.
♦ Avoid the effects of extreme heat or cold.
Important
Hazard due to loss of function of the motor bearing
♦ Avoid storing for too long (recommendation: max. 1 year).
♦ Check that the motor bearing functions properly before installation.
