Operating instructions

R3G280-RR05-N1

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.

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.

→ The maximum permissible vibration severity must not

exceed 3.5 mm/s and should be checked at intervals of 6
months. #It is to be determined at the motor mount at the
motor support plate at least in axial direction and
transversely to this. #Measurement of the vibration in all
three axes is recommended and should be performed over
the entire speed range in order to obtain a complete picture of
the vibrations occurring in the application, see Chapter 6.
Maintenance, malfunctions, possible causes and remedies.

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.

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.
