Operating instructions

W2D250-CH02-01

Translation of the original operating instructions

→ Wait five minutes after disconnecting the voltage at all poles

before opening the device.

CAUTION
In the event of a fault, the rotor and the impeller will be
energized

The rotor and the impeller have basic insulation.
→ Do not touch the rotor and impeller once installed.

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.

→ Wait until the device comes to a stop.

1.5 Safety and protective features

DANGER
Protective device missing and protective device not
functioning

Without a protective device there is a risk of serious injury, for
instance if the hands reach or are sucked into the device during
operation.
→ Operate the device only with a fixed protective device and

guard grille.# The fixed protective device must be able to
withstand the kinetic energy of a fan blade that becomes
detached at maximum speed. There must not be any gaps
which it is possible to reach into with the fingers, for example.

→ The device is a built-in component. As the operator, you

are responsible for ensuring that the device is secured
adequately.

→ Stop the device immediately if you notice a missing or

ineffective protective device.

1.6 Mechanical movement

DANGER
Rotating device

Risk of injury to body parts coming into contact with the rotor or
the impeller.
→ 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 and dangling items of clothing, jewelry and the like
can become entangled and be pulled into the device. Injuries
can result.
→ Do not wear any loose-fitting or dangling clothing or jewelry

while working on rotating parts.#Protect long hair with a cap.

1.7 Emissions

WARNING
Depending on the installation and operating conditions,
the sound pressure level may exceed 70 dB(A).

Risk of noise-induced hearing loss
→ Take appropriate technical safety measures.
→ Protect operating personnel with appropriate safety

equipment such as hearing protection.

→ Also observe the requirements of local agencies.

1.8 Hot surface

CAUTION
High temperature on motor housing

Risk of burns
→ Ensure sufficient protection against accidental contact.

1.9 Transport

NOTE
Transporting the device

→ Transport the device in its original packaging only.
→ Secure the device so it cannot slip, e.g. by using a

lashing strip.

1.10 Storage

;

Store the device, partially or fully assembled, in a dry and
weatherproof manner in the original packaging in a clean environment.

;

Protect the device against environmental effects and dirt until final
installation.

;

We recommend storing the device for no longer than one year in
order to guarantee trouble-free operation and the longest possible
service life.

;

Even devices explicitly intended for outdoor use are to be stored as
described prior to commissioning.

;

Maintain the storage temperature, see
Chapter 3.5 Transport and storage conditions.
