ABB DSDX404 remote input/output base unit
Term / Abbreviation MeaningPE Protective Earth
Phase module The phase module is a compact assembly of wired components including power semiconductors
and circuit boards that serves as a standardized building block for the DFE and the INU of the drive.
PPCS Power Plate Communication System
PPCS is an acronym for a serial communication protocol designed for data transfer via optical fibers
between AMC circuit board and INTerface circuit boards.
RTD Resistance Temperature Detector or Device
The RTD is a temperature sensor where the change in electrical resistance is used to measure the
temperature.
Safeline ABB synonym for uninterruptible power supply
Supervisory signal Indicates the operating condition of a circuit or device.
SW Software
TEU Terminal Unit
Short form for terminal compartment of the drive
Zero speed threshold Used in the manual to indicate that the drive has reached the value “zero speed” that is set in a
parameter. The value can be set in the range of 0 and maximum speed (the unit for the speed isrpm).

The main circuit breaker (MCB) is a major protec tion device of the drive. If a serious fault occurs in
the drive, the MCB must disconnect the main
power supply to the drive immediately. The main
power supply must be disconnected without delay
on an open or trip command from the drive to pre vent hazard to the personnel and further damage
to the equipment. The MCB is located on the pri mary side of the input transformer.
0-1 shows the conceptual single-line diagram of a
typical drive system, including main power supply,
MCB, input transformer, drive and electrical motor.
The MCB is defined as a switching device to dis connect the power supply whenever required by
the process or when a fault occurs. Typical devices
used as MCBs are:
• Vacuum circuit breakers
• SF6 circuit breakers
• Fused contactors or motor control centers
The overcurrent protection relay is part of the
switchgear.
