Operating instructions

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.

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

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.

;

When disconnecting, be sure to disconnect the ground connection last.

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.
The status relay drops out and the fault is reported via bus.

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’s danger zone.
→ When working on the device, switch off the line voltage

and ensure that it cannot be switched back on.

→ Wait until the device comes to a stop.
→ After working on the device, remove any tools 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.
