♦ To reduce transmission of vibration to the duct system, we recommend flexible connections from our accessory
range, see chapter Accessories.
Preconditions
♦ Ensure that the fan and all its components are
undamaged.
♦ Fit the fans in such a way that there is sufficient
access for installation, troubleshooting, maintenance
♦ Protect against dust and moisture when installing.

Damage to the motor and impeller.
The ball bearing of the motor and the balanced impeller may be damaged by forceful impacts.
♦ Attach the impeller and/or the shaft extension to the shaft or the rotor without forceful impacts.
♦ Do not separate the impeller and the hub. They were balanced as one unit by Systemair.
Note:
The hub can be heated for easier assembly and disassembly, for example with a hot-air blower.
• Precondition for assembly: the wedge is in the intended groove.
• Tools: hexagon socket wrench and suitable tool for removal, torque wrench for the taper clamping bush.

♦ Check if the data on the nameplate matches the
connection data.
♦ Complete the electrical connection according to the
circuit diagram.
♦ Connect the cable end in a dry environment.
♦ Install a circuit breaker in the permanent electrical
installation, with a contact opening of at least 3 mm
at each pole.
♦ Fans with EC- motors must be switched on/off via the
control input.
Protective grounding wire
The protective grounding must have a cross-section equal to or greater than that of the phase conductor.
Residual current circuit breaker
All-current-sensitive residual current circuit breakers are required for use in alternating-current systems with 50/60
Hz, in combination with electronic devices such as EC motors, frequency converters or uninterruptible power supplies
(UPS).
9.1 Electrical connection accessories
The following wiring diagrams show the electrical connections between accessories and
fans (with EC motor) or frequency converters (e.g. FRQ, FRQS, FXDM) which can be
controlled with a 0–10V signal. If you are not sure if your fan is equipped with an EC- motor
please see chapter 6 Name plate and type key, page 5.

9.2 Protecting the motor
Note:
In fans equipped with an EC motor, there is no additional motor protection needed. The motor protection is
integrated in the electronics of the motor.
Important
Damage to motor due to overcurrent, overload or short circiut.
♦ Lead-out temperature monitors must be integrated in the control circuit in such a way that, if a fault
occurs, the motor cannot switch on again automatically after it has cooled down.
♦ Motor lines and temperature monitor lines should be laid separately on principle.
♦ Without thermal protection: Use a motor protection switch!
IR24–P
9.3 Variable-speed fans
Warning
Resonant frequencies may result in increased vibration in certain speed ranges. These vibrations may
destroy components.
♦ Only operate the fan outside these speed ranges.
♦ Pass through these speed ranges so quickly that any vibration cannot exceed the admissible resonant
frequency values.
♦ Observe the operating instructions of the frequency converter.
| 004
Commissioning
Caution
Damage as a result of incorrect commissioning of the frequency converter.
♦ Install the fan and frequency converter as near as possible to one another.
♦ Use shielded cables.
♦ All components (fan, frequency converter and motor) must be grounded.
♦ Avoid running the fan via the frequency converter below 10 Hz.
♦ Heating of the motor due to use of a variable frequency drive must be checked in the application by the
customer.
♦ Never exceed the maximum impeller rotation speed indicated on the name plate of the fan.
♦ In any case Systemair recommends an all-pole sine filter if the fan is operated with a frequency
converter.
10 Commissioning
Warranty claims can only be made if commissioning work is carried out correctly and written evidence thereof is
provided.
Safety information
♦ Observe 2 Important safety information, page 1
Preconditions
|
11
♦ Installation and electrical connection have been
correctly performed.
♦ Before switching the fan on, check for externally
visible damage and ensure that the protective
equipment functions properly.
Commissioning of speed-controlled fans
Check the fan for vibrations at all normal operation speeds during commissioning. Determine and evaluate vibrations
on the housing and bearing areas in accordance with DIN ISO 14694 depending on motor power and positioning.
Measurable vibration velocities depend e.g. on following factors:
• positioning
The working point of the fan, as well as used external devices and accessories, also influence the running
characteristics.
Tests
Do the tests requested in the commissioning report (16 Commissioning Report, page 15)
• bottom section/foundation state • flow conditions
♦ Inlet and outlet are free.
♦ Cable glands are tight.
♦ Safety devices have been fitted.

12.2 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:
• Kitchen exhaust fans
• Durable ambient temperature > 30 ºC or < -10 ºC, or temperature fluctuations > 20 K
Table 7 Activities
Activity
Check the fan and its components for visible damage,
corrosion and contamination.
