W2D250-CI14-09

Translation of the original operating instructions

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
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
Guard missing and guard not functioning

Without a guard, hands may become caught up in the device
during operation for example, resulting in serious injury. Loose
parts or items of clothing could be drawn in.
→ The device is a built-in component. As the owner, you are

responsible for ensuring that the device is adequately
safeguarded.# Operate the device only with a fixed
protective device and guard grill.

→ Stop the device immediately if a protective device is

found to be missing or ineffective.

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

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

protected against the weather and free from vibration, 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
