4.4 Ventilation
When installing TMS7 starters in an enclosure there must be
sufficient air flow through the enclosure to limit heat rise within
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.
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
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
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
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
semiconductor fuses, if used, can be eliminated by installing
these within the bypass loop.
