2.11.1.3 External requirements
• One fan support bracket (50Y9743/01) must be used per assembly to provide mechanical stability
to the unit.
NOTE: Failure to fit this bracket may result in mechanical damage.
• As the fan assembly contains moving parts, the air outlet ducting (application dependant) should
prevent access to the unit by using appropriate grills or the ducting itself.
• The fan requires a 230V a.c. supply, which must be suitably protected with appropriate fusing.
rated to the voltage and current potential of the fan.
