Operating instructions

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.

→ Instantly stop the device once you detect a missing or

ineffective protective feature.

1.6 Mechanical movement

DANGER
Rotating device

Body parts coming 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.

1.8 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.

• Operating the device with all protective features in place.

• Minding the operating instructions.

Improper use

Using the device in the following ways is particularly prohibited and
may cause hazards:

• Moving air that contains abrasive particles.

• Moving highly corrosive air, e.g. salt spray mist. Exceptions are

devices that are intended for salt spray mist and protected accordingly.

• Moving air that contains dust pollution, e.g. suctioning off saw dust.

• Operating the device close to flammable materials or components.

• Operating the device in an explosive atmosphere.

4. CONNECTION AND START-UP

4.1 Connecting the mechanical system

CAUTION
Cutting and crushing hazard when removing the fan
from the packaging

→ Carefully seize the impeller to lift the device out of 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.
→ 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 touch 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.

4.2.2 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 live­earth) 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.

⇒ Connect the lines according to your application. When doing so,

observe chapter 4.4 Connection diagram.

4.2.1 Prerequisites

⇒ Check whether the data on the type plate agree with the connection

data and the data of the operating capacitor.

Translation of the original operating instructions

⇒ 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.
