Commissioning

8.1 Safety information
Commissioning may only be carried out by trained and instructed qualifi ed personnel!
»
8.2 Preconditions
•
Installation and electrical connection have been correctly performed.
•
Residual material from installation and foreign objects have been removed from the fan and ducts.
•
Inlet and outlet are free.
•
The safety devices have been fi tted (protective grille).
•
The earth wire is connected.
•
The cable glands are tight.
•
The nominal current (from the name plate) is not exceeded.
•
The data on the name plate corresponds with the connection data.
•
The supply voltage corresponds with the device voltage.
8.3 Notes
8.3.1 Reactive currents
An EMC fi lter is integrated to comply with the limit values for emitted interference and interference resistance. This
means that reactive currents in the power supply line can still be measured even if the motor is at standstill and the
power supply is activated.
•
The values typically lie in a range of <250 mA.
•
At the same time, the effective power in this operating state (stand-by) is typically <4 W.
8.3.2 Locked rotor protection
Due to the locked rotor protection, the start-up current (LRA) is equal to or smaller than the nominal current (FLA).
8.4

Tests when activated

" Switch the ventilator on.
WARNING
Danger from protruding parts!
Wear safety goggles when checking the direction of rotation.
»
" Check the direction of rotation/conveyance. The direction of rotation always applies looking at the rotor.
" Check:
•
Smooth running (any vibrations and noise)
•
Current consumption (with appropriate measuring instrument)
•
Tightness of all connections
