OPERATING TEMPERATURE
Under normal operation, the ceramic
pellet inside the case reaches a tem-
perature of 150
°
C. The plastic case
material has been recognized by UL for
operation up to this temperature. The
actual temperature on the outside of the
case will be approximately 100
°
C while
the motor is running. An appropriate
mounting location and 105
°
C, 600 volt
wiring are recommended.
