Operating instructions
CAUTION
In the event of failure, there is electric voltage at the
rotor and impeller
The rotor and impeller are base insulated.
→ Do not touch the rotor and impeller once they are installed.
CAUTION
If control voltage is applied or a speed setpoint is stored,
the motor automatically restarts, e.g. after a power failure.
Danger of injury
→ Keep out of the danger zone of the device.
→ When working on the device, switch off the mains
supply voltage and secure the latter from being switched on
again.
→ Wait until the device stops.
→ After working on the device, remove any used tools or
other objects from the device.
1.5 Safety and protective functions
DANGER
Missing safety device and non-functioning safety device
If there is no safety device, you could be seriously injured, for
example if you reach into the running device or your hands are
sucked into it.
→ Operate the device only with a fixed and isolating safety
protection and a fixed guard grille.
The guard must withstand the kinetic energy of a fan blade
detaching at maximum speed.
→ The device is a built-in component. You, the owner/
operator, are responsible for providing adequate protection for
the device.
→ Shut down the device immediately if you detect a
missing or ineffective protective feature.
1.6 Electromagnetic radiation
Interference from electromagnetic radiation is possible, e.g. in conjunction
with open and closed-loop control devices.
If unacceptable emission intensities occur when the fan is installed,
appropriate shielding measures have to be taken by the user.
NOTE
Electrical or electromagnetic interferences after
integrating the device in installations on the customer's
side.
→ Verify that the entire setup is EMC compliant.
1.7 Mechanical movement
DANGER
Rotating device
Body parts that come into contact with the rotor and impeller
can be injured.
Translation of the original operating instructions
→ Secure the device against accidental contact.
→ Before working on the system/machine, wait until all
parts have come to a standstill.
DANGER
Flying parts
Missing safety devices may cause balancing weights or
broken fan blades to be ejected at high speeds, causing bodily
harm.
→ Take appropriate safety measures.
WARNING
Rotating device
Long hair, loose items of clothing and jewellery could become
entangled and pulled into the device. You could be injured.
→ Do not wear any loose clothing or jewellery while working
on rotating parts.
→ Protect long hair by wearing a cap.
1.8 Emission
WARNING
Depending on the installation and operating conditions,
a sound pressure level greater than 70 dB(A) may arise.
Danger of noise-induced hearing loss
→ Take appropriate technical safety measures.
→ Protect operating personnel with appropriate safety
equipment, e.g. hearing protection.
→ Also observe the requirements of local agencies.

4. CONNECTION AND START-UP
4.1 Connecting the mechanical system
CAUTION
Cutting and crushing hazard when removing the blower
from the packaging
→ Carefully remove the blower from its packaging, only
touching the housing. Make sure to avoid any shock.
→ Wear safety shoes and cut-resistant safety gloves.
CAUTION
Heavy load when taking out the device
Bodily harm, e.g. back injuries, are possible.
→ Two people should remove the device out of its packaging
together.
; Check the device for transport damage. Damaged devices must no
longer be installed.
; Install the undamaged device according to your application.
4.2 Connecting the electrical system
DANGER
Electric voltage on the device
Electric shock
→ Always install a protective earth first.
→ Check the protective earth.
DANGER
Incorrect insulation
Risk of fatal injury from electric shock
→ Use only cables that meet the specified installation
requirements for voltage, current, insulation material, load etc.
→ Route cables such that they cannot be touched by any
rotating parts.
DANGER
Electrical load (>50 µC) between mains wire and
protective earth connection after switching of the supply
when switching multiple devices in parallel.
Electric shock, risk of injury
→ Make sure that sufficient protection against accidental contact
is provided.
Before working on the electrical connection, the
connections to the mains supply and PE must be shorted.
CAUTION
Electrical voltage
The device is a built-in component and features no electrically
isolating switch.
→ Connect the device only to circuits that can be switched off
using an all-pole disconnecting switch.
→ When working on the device, you must switch off the
system/machine in which the device is installed and secure
it from being switched on again.
NOTE
Water penetration into leads or wires
Water enters at the cable end on the customers side and can
damage the device.
→ Make sure that the cable end is connected in a dry
environment.

D3G318-AA37-11
Operating instructions
Connect the device only to circuits that can be switched off
using an all-pole disconnecting switch.
4.2.1 Prerequisites
; Check whether the data on the type plate agree with the connection
data.
; Before connecting the device, ensure that the supply voltage matches
the operating voltage of the device.
; Only use cables designed for current according to the type plate.
For determining the cross-section, follow the basic principles in
accordance with EN 61800-5-1. The protective earth must have a
cross-section equal to or greater than the outer conductor crosssection.
We recommend the use of 105°C cables. Ensure that the minimum
cable cross-section is at least
AWG26/0.13 mm².
Earth wire contact resistance to EN 61800-5-1
Compliance with the impedance specifications to EN 61800-5-1 for the
protective earth circuit must be verified in the end application.
Depending on the installation situation, it may be necessary to install an
additional protective earthing conductor via the additional protective earth
connection point available on the device.
The protective earth connection point is located on the housing and has
a protective earth symbol and a bore hole.
4.3 Connection of the cables
External leads are brought out of device.
; First connect the "PE" (protective earth) connection.
● Connect the lines according to your application. When doing so,
observe chapter 4.4 Connection screen.
4.2.2 Idle current
Because of the EMC filter integrated for compliance with EMC
limits (interference emission and interference immunity), idle
currents in the mains cable can be measured even when the
motor is at a standstill and the mains voltage is switched on.
● The values lie in a range of typical < 250 mA.
● The effective power in this operating state (readiness for operation) is
simultaneously at typical < 4 W.
4.2.3 Residual current operated device
Only universal (type B or B+) RCD protective devices are
permitted. Like frequency inverters, RCD protective devices
cannot provide personal safety while operating the device.
When switching on the power supply of the device, pulsed
charge currents from the capacitors in the integrated EMC filter
can lead to the RCD protective devices triggering without
delay. We recommend residual current devices with a trigger
threshold of 300 mA and delayed triggering (super-resistant,
characteristic K).
4.2.4 Locked-rotor protection
Due to the locked-rotor protection, the start-up current (LRA) is
equal to or less than the nominal current (FLA).

similar connectors by the customer.
WARNING
Hot motor housing
Fire hazard
→ Ensure that no combustible or flammable materials are
located close to the blower.
; Inspect the device for visible external damage and the proper function
of the protective features before switching it on.
; Check the air flow paths of the fan for foreign objects and remove any
that are found.
; Apply the nominal voltage to the voltage supply.
; Start the device by changing the input signal.
4.7 Switching off the device
Switching off the device during operation:
; Switch off the device via the control input.
; Do not switch the motor (e.g. in cyclic operation) on and off via power
supply.
Switching off the device for maintenance work:
; Switch off the device via the control input.
; Do not switch the motor (e.g. in cyclic operation) on and off via power
supply.
; Disconnect the device from the supply voltage.
; When disconnecting, be sure to disconnect the earth wire connection
last.
