fan must use
screened power
cable, max
length 30m.
Screening must
be earthed at
both ends.
BMS Signal
The system’s response to a 0-10V dc BMS signal is
given in the following table. Note the BMS signal will
override any sensors and user control connected in the
system. The voltage tolerance is +/_ 125mV and is
measured at the fans terminal.

Damper Connections (if required)
OP
- 230V 50Hz 1A max supply to open the damper
CL
- 230V 50Hz 1A max supply to close the damper
N
- Neutral supply to damper
RET
- 230V ac return signal from damper limit switch to
indicate the damper has reached its operating position.
If the return signal is not present, the fan will wait for
1 minute before starting.
Note: If a damper is not fitted, connect a link wire from OP
to RET. This will cancel the delay.
Glands supplied.
Warning -
When the fan is isolated, allow
5 minutes for the capacitors in the inverter to
discharge before commencing work on the unit.
Important! This product
must be earthed
5.0 Wiring Connections
Settings cont.
Setting the minimum trickle airflow (nominal 40%)
i) Repeat the same procedure as for maximum airflow
above but without the link wire between supply L and SL
terminal. Ensure the trickle switch is in the ‘ON’ position.
The adjustment must be made on the pot marked ‘Min’
ii) Note that the minimum setting (nominally 40%) must be
below the maximum setting, otherwise minimum setting will
be automatically set to be the same as the maximum.
