Translation of the original operating instructions

Motor/electronics
overtemperature

Deficient cooling

Improve cooling. Let
the device cool down.
To reset the error
message, switch off
the line voltage for at
least 25 s and then
switch it on again.

Ambient temperature
too high

Reduce the ambient
temperature.
Reset by reducing
control input to 0.

Impermissible point of
operation

Correct the operating
point. Let the device
cool down.

In the event of further malfunctions, contact ebm-papst.

6.1 Cleaning

To ensure a long service life, check the fans regularly for proper
operation and soiling. The frequency of checking is to be adapted
accordingly depending on the degree of soiling.

DANGER
Risk of injury from rotating fan.

→ Only clean when not in motion. Do not disconnect the fan

from the power supply, just switch it off via the control input.
This will prevent start-up of the fan.

;

Dirt deposits on the motor housing can cause overheating of the motor.

;

Soiling of the impeller can cause vibration that will shorten the service
life of the fan.

;

Severe vibration can destroy the fan.

;

In such cases, switch off the fan immediately and clean it.

;

The preferred method of cleaning is dry cleaning, e.g. using
compressed air.

;

Do not use aggressive cleaning agents!

NOTE
Damage to the device during cleaning

Malfunction possible
→ Do not clean the device using a water jet or high-pressure

cleaner.

→ Do not use any acid, alkali or solvent-basedcleaning

agents.

→ Do not use any pointed or sharp-edged objects for cleaning

;

Completely remove any cleaning agents used.

;

If severe corrosion is visible on load-bearing or rotating parts, switch
off the device immediately and replace it.

;

Repair of load-bearing or rotating parts is not permitted!

;

Operate the fan for 2 hours at maximum speed so that any water that
has ingressed can evaporate.

;

If cleaning does not eliminate vibrations, the fan may need to be
rebalanced. To have it rebalanced, contact ebm-papst.

;

The fan is equipped with maintenance-free ball bearings. The lifetime
lubrication of the ball bearings is designed for a service life of 40,000
hours.

;

If bearing replacement is necessary after that period, contact ebm-
papst.

;

Adapt the maintenance intervals to the actual level of dust exposure.

6.2 Safety inspection

NOTE
High-voltage test

The integrated EMC filter has Y capacitors. The tripping current
is exceeded when AC testing voltage is applied.
→ Test the device with DC voltage when you perform the

legally required high-voltage test. The voltage to be used
corresponds to the peak value of the AC voltage required by
the standard.

6.3 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.

6.3.1 Country-specific legal requirements

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
corresponding disposal standards are also to be heeded.
