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 closed back on again.
Terminal box tightening torque, see Chapter 3.1 Product
drawing.
Make sure the terminal box is correctly closed and sealed
and that all screws and cable glands are properly tightened.
4.7
Switch 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
connections. 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.
NOTE
Damage to the device from vibration
Bearing damage, shorter service life
→ Low-vibration operation of the fan must be
ensured over the entire speed control range.
Severe vibration can arise for instance from
inexpert handling, transportation damage and
resultant imbalance or be caused by component
or structural resonance. Speed ranges with
excessively high vibration levels and possibly
resonant frequencies must be determined in the
course of fan commissioning. Either run through
the resonant range as quickly as possible with
speed control or find another remedy. Operation
with excessively high vibration levels can lead to
premature failure.
4.8
Switching off the device
Disconnect the device from the power supply at the supply
line’s main switch.
When disconnecting, be sure to disconnect the ground
connection last.
5.
MAINTENANCE, MALFUNCTIONS, POSSIBLE CAUSES
AND REMEDIES
Do not perform any repairs on your device. Return the device to
ebm-papst A&NZ 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
Electrical charge on capacitor after device is
switched off
Electric shock, risk of injury
→ Discharge the capacitors before working on the
device.
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 mains
supply voltage and ensure that it cannot be
switched back on.
→ Wait until the device comes to a stop.
→ Install the externally wired thermal overload
protector in the control circuit so that following aa
malfunction the motor does not switch on again
automatically after cooling off.
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 condensate 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.
Mains supply
voltage faulty
Check mains supply
voltage, restore power
supply.
Faulty
connection
Isolate from supply,
correct connection,
see connection
diagram.
Thermal over-
load protector
activated
Allow motor to cool
off, locate and rectify
cause of error,
release restart lockout
if necessary.
