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.
