Table 7.2 Specific Peripheral Devices and Purposes
Purpose
Protects the main circuit and
devices wired to the main
circuit while providing
overload protection.
Switches off potentially
harmful leakage current.
Disconnects the power
supply and protects the
braking resistor.
power supply is too large.
Required for power supplies
greater than 600 kVA.
Harmonic suppression.
Improves the power factor of
the power supply
Reduces the amount of noise
flowing back into the power
supply.
Software for selecting drive
capacity, customizing, and
programming the drive.
Protects the drive in case of
short circuit.
