Operating instructions
4. CONNECTION AND STARTUP
4.1 Mechanical connection
CAUTION
Cutting and crushing hazard when removing device
from packaging
Blades can bend
→ Carefully remove the device from its packaging, by the fan
housing. Strictly avoid shocks.
→ Wear safety shoes and cut-resistant safety gloves.
NOTE
Damage to the device from vibration
Bearing damage, shorter service life
→ The fan must not be subjected to force or excessive vibration
from sections of the installation. #If the fan is connected to air
ducts, the connection should be isolated from vibration, e.g.
using compensators or similar elements. #Ensure stress-free
attachment of the fan to the substructure.
; Check the device for transport damage. Damaged devices are not to
be installed.
; Install the undamaged device in accordance with your application.
NOTE
Motor capacitor
→ The product is equipped withamotor capacitor with safety
protection class P0/S0 according to EN 60252-1. Take this
into consideration when fitting it to the end product on the
basis of applicable regulations.
CAUTION
Possible damage to the device
If the device slips during installation, serious damage can result.
→ Ensure that the device is securely positioned at its place of
installation until all fastening screws have been tightened.
4.2 Electrical connection
DANGER
Voltage on the device
Electric shock
→ Always connectaprotective earth first.
→ Check the protective earth.
DANGER
Faulty insulation
Risk of fatal injury from electric shock
→ Use only cables that meet the specified installation
regulations for voltage, current, insulation material, capacity,
etc.
→ Route cables so that they cannot be touched by any
rotating parts.
CAUTION
Voltage
The fan isabuilt-in component and has no disconnecting switch.
→ Only connect the fan to circuits that can be switched off with
an all-pole disconnection switch.
→ When working on the fan, secure the system/machine in
which the fan is installed so as to prevent it from being
switched back on.
NOTE
Water ingress into wires or cables
Water ingress at the customer end of the cable can damage the
device.
→ Make sure the end of the cable is connected inadry
environment.
Only connect the device to circuits that can be switched off with
an all-pole disconnection switch.
4.2.1 Requirements
; Check whether the data on the nameplate matches the connection data.
; If the motor run capacitor was not installed by Systemair, check
whether the information on the motor run capacitor matches the
information on the nameplate.
; Before connecting the device, make sure the power supply matches
the device voltage.
; Only use cables designed for the current level indicated on the
nameplate.
For determining the cross-section, note the sizing criteria according
to EN 61800-5-1. The protective earth must haveacross-section
equal to or greater than that of the phase conductor.
We recommend the use of 105 °C cables. Ensure that the minimum
cable cross-section is at least
AWG 26/0.13 mm².
Ground conductor contact resistance according to EN 60335
Compliance with the impedance specifications according to EN 60335
for the protective earth connection circuit must be verified in the end
application.
Depending on the circumstances of installation, it may be necessary to
connect an additional protective earth conductor to the extra protective
earth terminal on the device.
4.2.2 Voltage control
With speed control using transformers or electronic voltage
regulators (e.g. phase control), excessive current may occur.
In addition, depending on how the device is installed, noises
can occur with phase control.
4.2.3 Variable frequency drive
Please useavariable frequency drive only after consultation with Systemair.
For operation with variable frequency drives, install sinusoidal
filters that work on all poles (phase-phase and phase-ground)
between the drive and the motor.
During operation with variable frequency drives, an all-pole
sine filter protects the motor against high-voltage transients that
can destroy the coil insulation system, and against harmful
bearing currents.
Heating of the motor due to use ofavariable frequency drive must be
checked in the application by the customer.
