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.

;

Route the connecting cables in the terminal box so that the terminal
box cover closes without resistance.

;

Use all plug screws (the entire number). In doing so, insert the
screws manually to avoid damage to the thread.

4.6 Switch on device

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.

4.7 Switching off the device

Switching off the device during operation:

;

Switch on 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 on 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.

;

When disconnecting, be sure to disconnect the earth wire connection
last.

5. INTEGRATED PROTECTIVE FUNCTIONS

The integrated protective functions cause the motor to switch off
automatically in case of faults described in the table.

Malfunctions

Description / Function of
safety feature

Rotor position detection error

An automatic restart occurs.

Locked rotor

;

After the blockage is

removed, the motor restarts
automatically.
