SPECIAL MOTOR APPLICATIONS
Multiple Motors
When more than one motor is connected downstream from the TE2
Series starter, the internal electronic overload protection cannot provide
proper protection of the individual motors. Codes require the use of
separate OLRs for each motor, which would need to be external
devices.
In these instances the TE2 Series Overload protection should be turned
off, deferring protection to the separate OLRs. Care should be taken to
ensure that the External OLR is properly wired into the starter control
circuit to facilitate shutdown of the motor.
