The SCR’s generate about 3.3 watts of heat per running amp (motor FLA). If the control
is mounted in an enclosure, the installer must provide fans or blower with sufficient ventila-
tion. Fan or blower should be rated for at least 0.8 CFM per ampere of motor FLA rating.
Baldor provided enclosures are designed to dissipate the heat from the SCR’s.
