4.4  Ventilation
 
When installing TMS7 starters in an enclosure there must be 
sufficient air flow through the enclosure to limit heat rise within 
the enclosure. Temperature within the enclosure must be kept 
at, or below, the TMS7 maximum ambient temperature rating. 
 
If installing an TMS7 within a totally sealed enclosure a bypass 
contactor must be employed to eliminate heat dissipation from 
the soft starter during run. 
 
Soft starters dissipate approximately 4.5 watts per amp. The 
table below shows air flow requirements for selected motor 
currents. If other heat sources are installed in an enclosure 
along with the TMS7 an additional air flow allowance must be 
made for these items. Note that heat generation from 
semiconductor fuses, if used, can be eliminated by installing 
these within the bypass loop.
