ventilation
The WMX dimmers are cooled by a temperature controlled fan. The air intake is at the
bottom, and exhausts through slots at the top and top-front.
The WMX dimmers are intended for wall mounting in unenclosed spaces. Multiple
dimmer arrays should be spaced
at least
100mm apart vertically, and no more than
three dimmers high, to avoid excessive heating of the top dimmer. Dimmers should be
spaced
at least
50mm horizontally.
Dimmers should be mounted
at least
300mm from the floor to avoid excessive ingress
of dust and fluff, or as dictated by local building statutes. Dimmers must be mounted
at
least
150mm below ceilings or shelves for adequate ventilation.
Mounting within unventilated cupboards is not recommended. If the dimmers are
mounted within cupboards, allow
at least
150mm above and below the dimmer, and at
least 100mm at each side and the front of the dimmer. In addition, the cupboard must be
vented with
at least
400 cm
2
(eg 40cm x 10cm) per dimmer at the top and bottom of the
cupboard. Additional venting area will serve to further reduce internal dimmer
temperatures and will enhance the dimmer’s reliability.
