4.3 Electrical Specification
230V ~ 50Hz / 220V ~ 60Hz Class I. Motor thermally protected by
overload device. Cable: 1mm max. or min. Fuse: 3 amp (if fan is supplied
from a 5A lighting circuit, no local fuse is required).
Note: If 2 x 12 inch fans or 5x 6 or 9 inch fans are used in the same
operating mode in the same room they should all be controlled from
L5
the same DX-CON speed control. This avoids the possibility of one fan
L4
(if speed controlled at a lower flow rate) being stalled by the other
L3
fan(s).

Adequate make-up air provision sufficient to provide ventilation in
N
accordance with building regulations is required in all rooms. This
should be checked during commissioning with all fans in the same room
running together in all possible configurations.
DX Fan unit
The automatic shutters, motor bearings should be frequently inspected
and maintained to ensure they open fully/operate satisfactorily. Use of
an RCD and fused spur with 1A, Bussmann TDC180, BS1362, fuse
(Farnell order no: 1123029) for 1 fan or 2A, Bussmann TDC180, BS1362
fuse (Farnell order no: 1123032) for 2 or 3 fans is recommended.
Always confirm airflow direction before commissioning.
