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
The motor restarts automatically when operating voltage
is applied, 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.
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 by reaching into the running device with your hands.
→ 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 Mechanical movement
DANGER
Rotating device
Body parts that come into contact with the rotor and impeller
can be injured.
→ Secure the device against accidental contact.
→ Before working on the system/machine, wait until all
parts have come to a standstill.
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.
1.7 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 fan
from the packaging
→ Carefully hold the impeller to remove the device from its
packaging. Make sure to avoid any shock.
→ Wear safety shoes and cut-resistant safety gloves.
;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.
CAUTION
Electrical voltage
The fan is a built-in component and features no electrically
isolating switch.
→ Only connect the fan to circuits that can be switched off with
an all-pole separating switch.
→ When working on the fan, you must switch off the
installation/machine in which the fan 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.
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 and the data of the operating capacitor.
;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 cross-
section.
We recommend the use of 105°C cables. Ensure that the minimum
cable cross-section is at least
AWG26/0.13 mm².
4.2.2 Voltage control
With open loop speed control using transformers or electronic
voltage regulators (e.g. phase angle control), excessive current
may occur.
In addition, noises can occur with phase angle control
depending on the mounting situation.
4.2.3 Frequency inverter
Fit sinusoidal filters that work on all poles (live-live and live-
earth) between the frequency inverter and the motor for
operation with frequency inverters.
Depending on how the device is installed, noises may occur.
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.

4.5 Checking the connections
;Make sure that the power is off (all phases).
;Secure it from being switched on again.
;Check the correct fit of the connection lines.
4.6 Switch on device
WARNING
Hot motor housing
Fire hazard
→ Ensure that no combustible or flammable materials are
located close to the fan.
;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.
4.7 Switching off the device
;Disconnect the device from the supply voltage at the main switch for
the supply line.
;When disconnecting, be sure to disconnect the earth wire connection
last.
5. MAINTENANCE, MALFUNCTIONS, POSSIBLE
CAUSES AND REMEDIES
Do not perform any repairs on your device. Return the device to ebm-
papst for repair or replacement.
WARNING
Terminals and connections have voltage even with a
unit that is shut off
Electric shock
→ Wait five minutes after disconnecting the voltage at all poles
before opening the device.
CAUTION
Electrical load on the capacitor after device is switched off
Electric shock, risk of injury
→ Discharge the capacitors before working on the device.
CAUTION
The motor restarts automatically when operating voltage
is applied, 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.
If the device remains out of use for some time, e.g. when in
storage, we recommend switching the device on for at least
two hours to allow any condensate to evaporate and to move
the bearings.
