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.
; 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 with a motor 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 connect a protective 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 is a built-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.
Translation of the original operating instructions
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 in a dry
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 match the connection data
and the data for the operating capacitor.
; 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 have a cross-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 use a variable frequency drive only after consultation with ebmpapst.
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 of a variable frequency drive must be
checked in the application by the customer.
4.3 Connection via terminal strip
4.3.1 Connecting wires to terminals
WARNING
Live terminals and connections even with device
switched off
Electric shock
→ Wait five minutes after disconnecting the voltage at all poles
before opening the device.
; Insert the wires into the terminals, see
Chapter 4.4 Connection diagram.

; Make sure a restart is impossible
; Check the cables for proper fit.
4.6 Switching on the 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 hookup. This also applies for
devices which have already been equipped with plugs and terminals or
similar connectors by the customer.
WARNING
Hot motor housing
Risk of fire
→ Ensure that no combustible or flammable materials are
located close to the fan.
; Before switching on, check the device for visible external damage
and make sure the protective devices are functional.
; Check the fan's air flow paths for foreign matter and remove any
foreign matter found.
; Apply the nominal supply voltage.
4.7 Switching off the device
; Disconnect the device from the power supply at the supply line's
main switch.
; When disconnecting, be sure to disconnect the ground connection last.

5. MAINTENANCE, MALFUNCTIONS, POSSIBLE
CAUSES AND REMEDIES
Do not perform any repairs on your device. Send the device to ebmpapst for repair or replacement.
WARNING
Live terminals and connections even with device
switched off
Electric shock
→ Wait five minutes after disconnecting the voltage at all poles
before opening the device.
CAUTION
Electric charge on 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.
Risk of injury
→ Keep out of the device's danger zone.
→ When working on the device, switch off the line voltage
and ensure that it cannot be switched back on.

5.3 Disposal
For ebm-papst, environmental protection and resource preservation are
top priority corporate goals.
ebm-papst operates an environmental management system which is
certified in accordance with ISO 14001 and rigorously implemented
around the world on the basis of German standards.
Right from the development stage, ecological design, technical safety
and health protection are fixed criteria.
The following section contains recommendations for ecological disposal
of the product and its components.
5.3.1 Country-specific legal requirements
5.3.2 Disassembly
Disassembly of the product must be performed or supervised by
qualified personnel with the appropriate technical knowledge.
The product is to be disassembled into suitable components for disposal
employing standard procedures for motors.
WARNING
Heavy parts of the product may drop off. Some of the
product components are heavy. These components
could drop off during disassembly.
This can result in fatal or serious injury and material damage.
→ Secure components before unfastening to stop them falling.
5.3.3 Component disposal
The products are mostly made of steel, copper, aluminum and plastic.
Metallic materials are generally considered to be fully recyclable.
Separate the components for recycling into the following categories:
● Steel and iron
● Aluminum
● Non-ferrous metal, e.g. motor windings
● Plastics, particularly with brominated flame retardants, in accordance
with marking
● Insulating materials
● Cables and wires
● Electronic scrap, e.g. circuit boards
Only ferrite magnets and not rare earth magnets are used in external
rotor motors from ebm-papst Mulfingen GmbH & Co. KG.
; Ferrite magnets can be disposed of in the same way as normal iron
and steel.
Electrical insulating materials on the product, in cables and wires are
made of similar materials and are therefore to be treated in the same
manner.
The materials concerned are as follows:
● Miscellaneous insulators used in the terminal box
● Power cables
● Cables for internal wiring
● Electrolytic capacitors
Dispose of electronic components employing the proper procedures for
electronic scrap.
→ Please contact ebm-papst for any other questions on disposal.
NOTE
Country-specific legal requirements
Always observe the applicable country-specific legal
regulations with regard to the disposal of products or waste
occurring in the various phases of the life cycle. The
