This manual distinguishes two sorts of safety instructions. Warnings
are used to inform of conditions which can, if proper steps are not
taken, lead to a serious fault condition, physical injury and death. Notes
are used when the reader is required to pay special attention or when
there is additional information available on the subject. Notes are less
crucial than Warnings, but should not be disregarded.
Warnings Warnings are provided in the instruction manuals and on labels
attached to the AC drive. Readers are informed of situations that can
result in serious physical injury and/or serious damage to equipment
with the following symbols:
Notes Notes are provided in the instruction manuals to notify readers of the
need for special attention or additional information available on the
subject with the following symbols:
Dangerous Voltage Warning: warns of situations
in which a high voltage can cause physical injury
and/or damage equipment. The text next to this
symbol describes ways to avoid the danger.
General Warning: warns of situations which can
cause physical injury and/or damage equipment by
means other than electrical. The text next to this
symbol describes ways to avoid the danger.
Electrostatic Discharge Warning: warns of
situations in which an electrostatic discharge can
damage equipment. The text next to this symbol
describes ways to avoid the danger.
CAUTION! Caution aims to draw special attention to a
particular issue.
Note: Note gives additional information or points out
more information available on the subject.

Safety Instructions

Installation and
Maintenance Safety
These safety instructions are intended for all work on the ACx 600. In
addition to the instructions given below, there are more safety
instructions on the first pages of the appropriate hardware manual.
WARNING! All electrical installation and maintenance work on the
ACS 600 should be carried out by qualified electricians.
The ACS 600 and adjoining equipment must be properly grounded.
Do not attempt any work on a powered ACS 600. After switching off the
power, always allow the intermediate circuit capacitors 5 minutes to
discharge before working on the drive, the motor or the motor cable. It
is good practice to check (with a voltage indicating instrument) that the
drive is in fact discharged before beginning work.
The ACS 600 motor cable terminals are at a dangerously high voltage
when power is applied, regardless of motor operation.
The brake control terminals (UDC+, UDC-, R+ and R- terminals) carry
a dangerous DC voltage (over 500V).
There can be dangerous voltages inside the ACx 600 from external
control circuits when the ACx 600 input power is shut off. Exercise
appropriate care when working with the unit. Neglecting these
instructions can cause physical injury and death.
WARNING! The ACS 600 introduces electric motors, drive train
mechanisms and driven machines to an extended operating range.
The ACS 600 can be adjusted to operate the motor at speeds above
and below the speed provided by connecting the motor directly to the
power line. Before adjusting the drive and putting it into service, make
sure that the motor and all driven equipment is suitable for operation
throughout the speed range provided by the AC drive.
WARNING! If an external source for start command is selected and it is
ON, the ACS 600 will start immediately after fault reset unless the drive
is configured for 3-wire Start/Stop.
WARNING! When the control location is not set to Local (L not shown
in the status line of the display), the Stop key on the Control Panel will
not stop the drive. To stop the drive using the Control Panel you must
press the LOC/REM key and then the Stop key .
WARNING! The printed circuit boards contain integrated circuits that
are extremely sensitive to electrostatic discharge. Exercise appropriate
care when working on the unit to avoid permanent damage to the
circuits. Do not touch the boards unnecessarily.

Safety Instructions

WARNING! There are several automatic reset functions in the ACx
600. If selected, they reset the unit and resume operation after a fault.
These functions should not be selected if other equipment is not
compatible with this kind of operation, or dangerous situations can be
caused by such action.
Supply Connections
The ACx 601 does not include a disconnecting means. An input power
disconnecting means must be installed between the AC power source
and the ACx 601. The disconnecting means must conform to the
applicable safety regulations. The disconnecting means must be
locked in the open position during installation and maintenance work.
The motor must not be controlled with the supply disconnecting means;
instead, the and keys of the Control Panel or commands via
the I/O board of the ACx 600 should be used. The maximum number of
charging cycles of the d.c. capacitors of ACx 600 (i.e. power-ups by
applying power) is five in ten minutes.
WARNING! Never connect the line power to the ACx 600 output
terminals U2, V2, or W2. If frequent bypassing is required, mechanically
interlocked switches or contactors should be employed. Line voltage
applied to the output can result in permanent damage to the unit.
Operation outside the nominal input line voltage range should not be
attempted, as overvoltages can result in permanent damage to the
ACx 600.
If an ACx 601 with the integrated EMC filter (code 0 in the type code for
EMC Filters) is connected to an ungrounded power system or high
resistance grounded power system (over 30 Ohms), the power line will
be connected to ground potential through the EMC filter capacitors of
the ACx 601. This may cause danger or damage the unit. Disconnect
the EMC filter capacitors before connecting the ACx 601 to an
ungrounded power system. For detailed instructions on how to do this,
please contact your local ABB distributor.
Ground Fault
Protective Function
The ACx 600 (with Standard and Motion Control Application Programs)
is equipped with an internal ground fault protective function to protect
the unit against ground faults in the drive, the motor and the motor
cable. This is not a personal safety or a fire protection feature. The
ground fault protective function of the ACS/ACP 600 can be disabled
by Parameter 30.17 (ACC: 30.11).
The EMC filter of the ACx 600 includes capacitors connected between
the power circuit and the chassis. These capacitors increase the
ground leakage current from the AC line through the ground (PE)
connection and may cause some ground fault current circuit breakers
to trip.

Safety Instructions

Emergency Stop
Devices
The person responsible for the overall design and operation of the
driven process must make sure that the installation includes
emergency stop devices and any other safety equipment that may be
needed. Pressing the STOP key on the Control Panel of ACx 600 does
not generate an emergency stop of the motor or separate the drive
from dangerous potential. A Line Contactor with provisions for a
remote power cut-off switch is available as a factory installed option for
the ACx 607. Cutting off power to the drive allows the motor to coast to
a stop.
Ground Connections
The ACS 600 and adjoining equipment must be properly grounded.
The ACS 600 and the motor must be grounded at the installation site to
ensure personnel safety in all circumstances and in addition to reduce
electromagnetic emission and pick-up. Make sure that grounding
conductors are adequately sized as required by safety regulations.
In CE compliant installations and in other installations where EMC
emissions must be minimized, 360 degree high frequency grounding of
cable entries is done in order to suppress electromagnetic
disturbances. In addition, power cable shields must be connected to
the ground (PE) in order to meet safety regulations. Power cable
shields are suitable for use as equipment grounding conductors only
when the shield conductors are adequately sized as required by safety
regulations.
The ACS 600 ground terminals should not be connected in series in
case of a multiple installation. Incorrect grounding can cause physical
injury, death or equipment malfunction and increase electromagnetic
interference.
Motor Connections
WARNING! Operation is not allowed if the motor nominal voltage is
less than one half of (ACP: 0.4 times) the ACx 600 nominal input
voltage, or the motor nominal current is less than 1/6 of the ACx 600
nominal output current.
WARNING! Do not make any voltage tolerance or insulation resistance
test (Hi-Pot or Megger) on any part of the ACx 600. Disconnect motor
wires before making any tests of the motor or the cables between the
drive and motor.
Motor Insulation
Requirements
As with all AC drives employing the most modern IGBT invertor
technology, the output waveform of the ACx 600 consists of a series of
rectangular voltage pulses. Regardless of the output frequency, the
