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.

CAUTION
Device weighs over 25 kg! Heavy load when unpacking
device.

Risk of physical injury, such as back injuries.
→ Use suitable hoisting equipment to remove the device from

its packaging.

CAUTION
The blades of the impeller could be damaged.

→ Carefully set down the fan on a soft surface. Make sure the

blades are not subjected to load.

→ Following installation, make sure the impeller moves

easily and that the blades of the impeller are not deformed or
bent and do not catch at any point.

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.

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.

Recommendation for fastening AxiCool fan with screws: (based on VDI
2230)

;

Use screws of strength class 8.8.

;

For sizes 500 and 630, screws M8 with a tightening torque of max.
20 Nm.

;

For size 800, screws M10 with a tightening torque of max. 40 Nm.

The tightening torques specified above are based on the following values
are only valid for them:

The contact surfaces must be flat.

The fan must not be strained on fastening.

As every application is different, the tightening torque recommended
by ebm-papst must be checked in the application concerned.

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.

DANGER
Electrical charge (>50 µC) between phase conductor and
protective earth connection after switching off supply
with multiple devices connected in parallel.

Electric shock, risk of injury
→ Ensure sufficient protection against accidental contact.

Before working on the electrical hookup, short the supply
and PE connections.

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.

NOTE
Device malfunctions possible

Route the device's control lines separately from the supply line.
→ Maintain the greatest possible clearance.

Recommendation: clearance > 10 cm (separate cable
routing)

NOTE
Water ingress into wires or cables

Water ingresses at the customer cable end and can damage the
device.
→ Make sure the end of the cable is connected in a dry

environment and that the connection point is lower than the
motor if possible.

Only connect the device to circuits that can be switched off with
an all-pole disconnection switch.

4.2.1 Requirements

;

Check whether the information on the nameplate matches the
connection data.

;

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
