You must use an enclosure to protect the electronics of the Push Button
Module from atmospheric contamination. Standards established by the
National Electrical Manufacturer’s Association (NEMA) define enclosure
types based on the degree of protection an enclosure will provide.
Heat Dissipation
Within the enclosure, the Push Button Module (or Modules) requires room
for convection cooling.
In some applications, other equipment inside (or outside) the enclosure may
produce too much heat. Place blower fans inside the enclosure to circulate
air to reduce hot spots near components. In extreme cases, use air
conditioning to prevent heat build-up.
!
ATTENTION: Do not use unfiltered outside air. It could
contain contaminants or dirt harmful to the components.
