Input Power Connections
Branch Circuit Protection
Input power is connected to the ACQ550 with Bypass through a circuit breaker that
provides the branch circuit short circuit and ground fault protection for the motor
operating in the bypass mode.
Fuses
Drive input fuses are provided to disconnect the drive from power in the event that a
component fails in the drive’s input power circuitry. The drive’s electronic protection
circuitry is designed to clear drive output short circuits and ground faults without
blowing the drive input fuses. Drive input fuses are shown in the following tables.
Note!
Although fuses listed are similar in functional characteristics to fuses listed in
the ACQ550-U1 User’s Manual, physical characteristics may differ. Fuses from other
manufacturers can be used if they meet the functional characteristics of those shown
in the tables.
