Fast Acting Current-Limiting Fuses - Rockwell Automation Allen-Bradley SMC Dialog Plus Quick Start Manual

Quick Start
6
Pump Control
ATTENTION: Pump stopping is not intended to be used as an
emergency stop. Refer to the applicable standard for emergency stop
requirements.
ATTENTION: Pump stopping may cause motor heating depending on
the mechanical dynamics of the pumping system. Therefore, select the
lowest stopping time setting that will satisfactorily stop the pump.
Preset Slow Speed
ATTENTION: Slow speed running is not intended for continuous
operation due to reduced motor cooling.
SMB™ Smart Motor Braking Option
ATTENTION: SMB Smart Motor Braking is not intended to be used as
an emergency stop. Refer to applicable standards for emergency stop
requirements.
Accu-Stop™ and Slow Speed with Braking
ATTENTION: Accu-Stop and Slow Speed with Braking are not
intended to be used as an emergency stop. Refer to applicable
standards for emergency stop requirements.

Fast Acting Current-limiting Fuses

ATTENTION: The fast acting current-limiting fuses specified in Table
2.C of the user manual may not provide branch circuit protection.
Branch circuit protection in accordance with applicable electrical codes
may require additional fusing (or a circuit breaker) even though fast
acting current-limiting fuses are used.
ATTENTION: Applications requiring extended acceleration times or
high duty cycles may experience nuisance tripping of the coordinated
fast acting current-limiting fuses. This type of fuse has a limited
thermal capacity that is less than that of the SCRs they are designed to
protect. This makes them susceptible to thermal fatigue.
