Translation of the original operating instructions
4.6 Checking connections
;
Ensure isolation from supply (all phases).
;
Make sure a restart is impossible
;
Check the cables for proper fit.
;
Screw the terminal box cover back on again. Terminal box tightening
torque, see Chapter 3.1 Product drawing.
;
Route the cables in the terminal box so that the terminal box cover
closes without resistance.
;
Use all screw plugs. Insert the screws by hand to avoid damage to
the threads.
;
Make sure the terminal box is completely closed and sealed and that
all screws and cable glands have been properly tightened.
4.7 Switching on the device
The device may only be switched on if it has been installed properly and
in accordance with its intended use, including the required safety
mechanisms and professional electrical hookup. This also applies for
devices which have already been equipped with plugs and terminals or
similar connectors by the customer.
WARNING
Hot motor housing
Risk of fire
→ Ensure that no combustible or flammable materials are
located close to the fan.
;
Before switching on, check the device for visible external damage
and make sure the protective devices are functional.
;
Check the fan's air flow paths for foreign matter and remove any
foreign matter found.
;
Apply the nominal supply voltage.
;
Start the device by changing the input signal.
4.8 Switching off the device
Switching off the device during operation:
;
Switch off the device via the control input.
;
Do not switch the motor (e.g. in cyclic operation) on and off via power
supply.
Switching off the device for maintenance:
;
Switch off the device via the control input.
;
Do not switch the motor (e.g. in cyclic operation) on and off via power
supply.
;
Disconnect the device from the power supply.
5. INTEGRATED PROTECTIVE FEATURES
The integrated protective functions cause the motor to switch off
automatically in the event of the faults described in the table.
Fault
Safety feature description/
function
Rotor position detection error
An automatic restart follows.
Blocked rotor
;
After the blockage is
removed, the motor restarts
automatically.
Line undervoltage (line voltage
outside of permitted nominal
voltage range)
;
If the line voltage returns to
permitted values, the motor
restarts automatically.
Phase failure
A phase of the supply voltage
fails for at least 5 s.
;
When all phases are
correctly supplied again, the
motor automatically restarts after
10-40 s.
6. MAINTENANCE, MALFUNCTIONS, POSSIBLE
CAUSES AND REMEDIES
Do not perform any repairs on your device. Send the device to ebm-
papst for repair or replacement.
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
If control voltage or a stored speed set value is applied,
the motor will restart automatically, e.g. after a power
failure.
Risk of injury
→ Keep out of the device danger zone.
→ When working on the device, switch off the line voltage
and ensure that it cannot be switched back on.
→ After working on the device, remove any tools or other
objects from the device.
If the device is out of use for some time, e.g. when in storage,
we recommend switching it on for at least two hours to allow
any condensation to evaporate and to move the bearings.
Malfunction/fault
Possible cause
Possible remedy
Impeller not
running smoothly
Imbalance in rotating
parts
Clean the device;
replace it if imbalance
persists after cleaning.
Make sure no
weight clips are
removed during
cleaning.
Motor not turning
Mechanical blockage
Switch off, isolate
from supply and
remove mechanical
blockage.
