Attention!
It is critical that any enclosure is sized and selected to accomodate
and dissipate heat rise generated from all installed devices.
The table (right) provides maximum permissible heat dissipation for
each golf enclosure size. Please ensure that you calculate internal
heat generated from your installation and select the correct
enclosure accordingly.
