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
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 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.

1.8 Hot surface

CAUTION
High temperature at the motor housing

Danger of burn injuries

→ Ensure that sufficient protection against accidental contact is

provided.

1.9 Transport

NOTE
Transport of device

→ Transport the device in its original packaging only.

→ Secure the device so that it does not slip, e.g. by using a

clamping strap.

1.10 Storage

; Store the device, partially or fully assembled, in a dry and

weatherproof manner in the original packing in a clean environment.

; Protect the device from environmental impacts and dirt until the final

installation.

; We recommend storing the device for a maximum up to one year to

guarantee proper operation and longest possible service life.

; Even devices explicitly suited for outdoor use are to be stored as

described prior to being commissioned.

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.

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

Please use a frequency converter only after consultation with ebm-papst.

Fit sinusoidal filters that work on all poles (live-live and live­earth) between the frequency inverter and the motor for
operation with frequency inverters.
Depending on how the device is installed, noises may occur.

Heating of the motor due to use of a frequency converter must be
checked in the application by the customer.

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.

4.2.1 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

Translation of the original operating instructions

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

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

The device may only be switched on if it has been installed properly and
in accordance with its intended use, including the required safety
mechanisms and professional electrical connection. This also applies for
devices which have already been equipped with plugs and terminals or
similar connectors by the customer.

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

5. MAINTENANCE, MALFUNCTIONS, POSSIBLE
CAUSES AND REMEDIES

Do not perform any repairs on your device. Return the device to ebm­papst 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.
