• Cover or restrict adjacent live parts
3 Warranty
The warranty for our products is determined by the contractual stipulations, our offers and our Terms and Conditions.
Warranty claims presuppose that the product is properly connected, operated according to data sheets and serviced as
needed. A correct commissioning report must also be presented upon request. Please find the commissioning report attached to this document.
4 Delivery, transport, storage
4.1 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 2.2 Personal protective equipment,
page 2.
♦ Do not walk under suspended loads.
| 003
Delivery, transport, storage |
♦ Make sure that there is nobody under a suspended load.
4.2 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 completeness of the delivery.
♦ Check the packaging for transport damage.
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 2.2 Personal protective
equipment, page 2.

4.3 Transport
4.3.1 Safety information
Warning: Electrical or mechanical hazards due to fire, moisture, short circuit or malfunction.
♦ Never transport the fan by the connecting wire, terminal box, rotor, protective 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.
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.
4.4 Storage
4.4.1 Safety information
Warning: Risk of injury and damage to the fan.
♦ Do not stack the fans on top of one another.
♦ Do not use transport packaging as hoisting aids.
♦ Use hoisting equipment that is suitable for the weight to be hoisted.
4.4.2 Preconditions
♦ Store the devices in a clean, dry and vibration-free environment.
♦ Storage temperature should be between –20°C and 60°C.
4.4.3 Long storage time
Storage more than 3 months
♦ Turn the rotor at least 10 revolutions once a month.
♦ Please ensure that the rotor is at a different position afterwards.

Storage more than 12 months
♦ We recommend an inspection by the after-sales service of Systemair before commissioning.
Test the motor windings:
♦ Measure the insulation resistance of each motor winding against grounding at 500 V DC. The insulation resistance
must be > 10 mΩ.
Measures for an insulation resistance < 10 mΩ:
1. If the motor has drain plugs, remove them to allow any moisture to drain and replace them when the motor windings
are suitably dry.
2. Dry the motor in a warm dry airflow (typically 40 degrees Celsius).
3. Measure the insulation resistance of each motor winding against grouding at 500 V DC.
4. Repeat the aforementioned steps until the measurement outcome > 10 mΩ.
Test the motor:
♦ Connect an ammeter to each phase of the motor.
♦ Switch the fan on and check the current consumption.
♦ Compare the current consumption with the nominal consumption on the name plate.
5 Description
5.1 General
• The fan conveys air in an axial direction from the intake side via the electric motor to the outlet side. (except AXCBF).
• The electrical connection is made through a terminal box installed on the outside of the housing (except AXCBF).
5.1.1 Sensors (optional)
Sensors can be connected to the fan to monitor the roller bearings and for vibration monitoring.
5.1.2 Standstill heating (optional)
The standstill heating starts when the motor switches off and vice versa.
5.1.3 Technical data of the fan
The technical data of the fan can be seen on the name plate or the data sheet.
5.1.4 Motor data
The motor data can be found on the name plate of the motor or in the technical documents of the motor manufacturer.
