The DOMUS range of 12 Volt transformers
must be used when installing a Domus SELV
axial fan (see pages 54, 65 and 69).
Transformers must be mounted away from
any source of water spray and out of the
safety critical area (zone 0,1 or 2 as stated in
amendment 3 of BS7671:1992).
The transformers are fitted with multiple
control options to suit the whole Domus SELV
range of fans and incorporate a green LED to
indicate that the system is in operation.
