• Take into account information on the commissioning of other parts of the
system.
• The Airblock can be put into operation after conducting the above checks
by switching on the power supply to the motor terminal box, switching
on the fan modules on the motor terminal box and changing the
0-10 VDC input signal or by transmitting a signal via the MODBUS RTU
interface.

- Are all the impellers running smoothly or are grinding noises audible?
Determine the cause as soon as grinding noises become audible.
Switching off the units:
- Switch off the unit during operation via the control input.
- Do not switch the unit off and on (e.g. in cycle mode) via the mains
power.
- Make sure that the earth conductor connection is disconnected last when
disconnecting the unit.
