installation
Cooling air flows inside motor directly
from the outside using fan
The air inside the motor recirculates
and is cooled by heat transfer through
the frame.
Water dripping at up to a 15 degree
angle from vertical will not enter the
motor
Water projected by a nozzle against
the enclosure from any direction shall
have no harmful effect.
Dust ingress easily to the motor frameProtection against harmful deposits of
dust.
Winding must be double impregnated
to protect insulation against dust--
