Make sure that the power is off (all phases).
Secure it from being switched on again.
Check the correct fit of the connection lines.
Apply the nominal voltage to the voltage supply.
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
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
motor
WARNING
Terminals and connections have voltage even with a
unit that is shut off
Electric shock
CAUTION
Electrical load on the capacitor after device is switched off
Electric shock, risk of injury
CAUTION
The motor restarts automatically when operating voltage
is applied, 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.
Discharge the capacitors before working on the device.
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
Thermal overload
protector responded
Imbalance in rotating
parts
Ambient temperature
too high
Unacceptable
operating point
Insufficient cooling
Possible remedy
Switch off, de-
energise, and remove
mechanical blockage
Check mains supply
voltage, restore power
supply
Correct connection,
see connection diagram
Allow motor to cool
off, locate and rectify
cause of error, if
necessary cancel
restart lock-out
Clean the device, if
imbalance still evident
after cleaning, replace
device
Lower ambient
temperature if possible
Check operating point
Improve cooling
