General information on manual and equipment
EMC Electromagnetic compatibility
All measures to suppress electromagnetic disturbances
caused by different electrical equipment in the same
electromagnetic environment, and to strengthen the
immunity of the equipment to such disturbances.
Equipment ACS2000 and related equipment
Ground Earth
To ground The conducting path (e.g. conductor) between the
electric equipment (e.g. frequency converter) and the
earth. The electric equipment is connected to the earth,
e.g. by a grounding set or a grounding switch.
IFU Input filter unit
The IFU is a tuned filter: inductors, resistors and
capacitors that reduce harmonic voltages injected to the
supply network.
INT Interface
INU Inverter unit of the drive. The INU converts the DC
voltage to the required AC motor voltage and frequency.
IOEC module Term of ABB’s I/O system. The I/O module is an active
input or output device for digital or analog signals.
LED Light emitting diode
Line voltage RMS voltage of the main power supply of the drive – line
to line
LV Low voltage
MCB MV switchgear
MV switchgear Medium voltage switchgear isolation device
The MV switchgear is a mandatory inter-connection
device of the drive system and connects / disconnects
the main power supply to the drive. The MV switchgear
must be controlled entirely by the drive.
NP Neutral point
PCB Printed circuit board
PE 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 AFE and INU of the drive.
PPCS Power plate communication system
PPCS is an acronym for a fieldbus communication
protocol designed for high speed data transfer via fiber-
optic cables between the AMC circuit board and phase
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
TEU Short form for terminal entry unit of the drive
