Operating instructions

R3G280-RU26-81

Translation of the original operating instructions

4.5 Checking the connections

;

Make sure that the power is off (all phases).

;

Secure it from being switched on again.

;

Check the correct fit of the connection lines.

4.6 Switch on device

The device is not to be switched on until it has been installed properly
and in accordance with its intended use, including the required protective
devices and professional electrical connection. This also applies to
devices which have already been equipped with plugs and terminals or
similar connectors by the customer.

WARNING
Hot motor housing

Fire hazard
→ Ensure that no combustible or flammable materials are

located close to the fan.

;

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.

NOTE
Damage to device by vibrations

Bearing damage, reduced service life
→ The fan must operate free of vibrations throughout its speed

control range.

→ Strong vibrations can result from improper handling,

imbalance resulting from damage during transport, or
component-induced or structural resonances.

→ When putting the fan into service, determine the speed

ranges with excessive vibration levels and also any
resonance frequencies that may be present.

→ When regulating the speed, pass through resonance

ranges as quickly as possible or find another remedy.

→ Operation at excessive vibration levels can lead to

premature failure.

→ The maximum vibration severity may not exceed 3.5 mm/s

and should be checked every 6 months. #It must be
measured at least in and perpendicular to the axial direction
at the place where the motor is attached to the motor support
plate. #Vibration measurements in all three axes are
recommended and should be performed across the entire
speed range in order to gain a complete understanding of all
vibrations present in an application; see chapter 5.
Maintenance, malfunctions, possible causes and remedies.

4.7 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 work:

;

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 supply voltage.

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.

WARNING
Terminals and connections have voltage even with a
unit that is shut off

Electric shock
→ Wait five minutes after disconnecting the voltage at all poles

before opening the device.

CAUTION
If control voltage is applied or a speed setpoint is stored,
the motor will restart automatically, e.g. after a mains
failure.

Risk of injury
→ Keep out of the device hazard zone.
→ When working on the device, switch off the mains power

and ensure that it cannot be switched back on.

→ Wait until the device stops.
→ After working on the device, remove any tools used or

other objects from the device.

NOTE

If the device is not operated for a lengthy period in installed
condition in a dry environment, it is to be started up and
operated at full speed for one hour at least every four months. If
the device is not operated for a lengthy period in installed
condition in a damp environment (e.g. outdoors), it is to be
started up and operated at full speed for at least two hours once
a month to move the bearings and allow any condensate that
may have ingressed to evaporate.

Malfunction/error

Possible cause

Possible remedy

Impeller running
roughly

Imbalance in rotating
parts

Clean the device; if
imbalance is still
evident after cleaning,
replace the device.
If you have
attached any weight
clips during cleaning,
make sure to remove
them afterwards.

Motor does not turn

Mechanical blockage

Switch off, de-
energise, and
remove mechanical
blockage.

Mains supply voltage
faulty

Check mains supply
voltage,
restore power
supply,
apply control signal.

Faulty connection

De-energise, correct
connection, see
connection diagram.
