Prevent Excessive Heat
36
Consider the following to help prevent excessive heat for your DG safety relay
and tap.
DG Safety Relay
For most applications, normal convective cooling keeps the DG safety relay
within the specified operating range. Verify that the specified temperature
range is maintained. Proper spacing of components within an enclosure is
usually sufficient for heat dissipation.
In some applications, other equipment inside or outside the enclosure produce
a substantial amount of heat. In this case, place blower fans inside the enclosure
to help with air circulation and to reduce hot spots near the controller.
Additional cooling provisions can be necessary when high ambient
temperatures are encountered. Do not bring in unfiltered outside air. Place the
controller in an enclosure to help protect it from a corrosive atmosphere.
Harmful contaminants or dirt can cause improper operation or damage to
components. In extreme cases, you may need to use air conditioning to help
protect against heat buildup within the enclosure.
Taps
The taps have no spacing requirements.
