RF Fans<br />
Example A<br />
RF Fans without Output Control<br />
Figure 5 – Fan connection<br />
Application of the RF fan in a simple air-handling<br />
assembly (separately) without output control, operation<br />
ON/OFF<br />
This connection ensures:<br />
Internal or standard thermal protection of the<br />
fan<br />
Manual switching on/off of the fan using the switch<br />
or STE(D) protecting relay.<br />
<br />
RF 40/19-2E<br />
RF 40/22-2E<br />
RF 40/23-2E<br />
RF 40/28-4E<br />
RF 56/31-4E<br />

RF 56/35-4D<br />
RF 56/40-4E<br />

RF 71/xx<br />
RF 100/xx<br />

230V / 50Hz<br />
(3x 400V / 50Hz)<br />
Example B<br />
RF Fans with Single-Phase Motor and Output<br />
Control using PE Controllers<br />
Figure 6 – Fan connection<br />
It is same as the previous example plus electronic controller<br />
inserted into the power supply. The PE controller<br />
enables the fan to be switched off.<br />
This connection ensures:<br />
Internal or standard thermal protection<br />
of the fan<br />
Manual switching on/off of the fan using the PE controller<br />
or STE(D) protecting relay.<br />
The number behind the PE controller indicates the value<br />
of max. permissible current load, which must be lower<br />
than the value of the fan motor current.<br />
