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 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 plug screws. Insert the screws by hand to avoid
damage to the thread.
Make sure that the terminal box is completely closed 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
connection. This also applies for devices that have already been
equipped with plugs and terminals or similar connections by the
customer.
WARNING
Hot motor housing
Risk of fire hazard
→ 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 devices are functional.
Check the air flow paths of the fan for foreign objects and
remove any that are found.
Apply the nominal supply voltage.
Start the device by changing the input signal.
4.8
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

INTEGRATED PROTECTIVE FUNCTIONS
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-under voltage
(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.
