Make sure that the power is off (all phases).
Secure it from being switched on again.
Check that the mating connector is correctly locked into the panel
connector.
Check that the mating connector is correctly crimped to the
connection line.
Inspect the device for visible external damage and the proper function
of the protective features before switching it on.
Check the air flow paths of the fan for foreign objects and remove any
that are found.
Apply the nominal voltage to the voltage supply.
Start the device by changing the input signal.
Disconnect the device from the supply voltage.
WARNING
Hot motor housing
Fire hazard
Ensure that no combustible or flammable materials are
located close to the fan.
Operating instructions
5. MAINTENANCE, MALFUNCTIONS, POSSIBLE
CAUSES AND REMEDIES
Motor and electronics enclosure are sealed by ebm-papst. Changes or
repairs may be carried out by ebm-papst only.
Do not perform any repairs on your device. Return the device to ebm-
papst for repair or replacement.
Malfunction/error
Motor does not turn
Impeller running
roughly
Overtemperature of
electronics/motor
WARNING
Terminals and connections have voltage even with a
unit that is shut off
Electric shock
CAUTION
If control voltage is applied or a speed setpoint is stored,
the motor automatically restarts, e.g. after a power failure.
Danger of injury
If the device remains out of use for some time, e.g. when in
storage, we recommend switching the device on for at least 2
hours to allow any condensate to evaporate and to move the
bearings.
Wait for five minutes after disconnecting the voltage at all
poles before touching the unit.
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.
Possible cause
Mechanical blockage
Mains supply
voltage faulty
Faulty connection
Imbalance in rotating
parts
Insufficient cooling
Ambient temperature
too high
Possible remedy
Switch off, de-
energise, and
remove mechanical
blockage
Check mains supply
voltage, restore
power supply
apply control signal
Correct connection,
see connection diagram
Clean the device; if
imbalance is still
evident after
cleaning, replace
device.
If you have
attached any weight
clips during cleaning,
make sure to
remove them
afterwards.
Improve cooling if
possible.
Reset by switching
off the mains supply
voltage for at least
20 s after motor
standstill
Lower ambient
temperature if
possible.
