ACS 300 User’s Manual iii
Safety Instructions
Overview
This chapter states the safety instructions which must be followed
when installing, operating and servicing the ACS 300. If
neglected, physical injury and death may follow, or damage may
occur to the frequency converter, the motor and driven
equipment. The material in this chapter must be studied before
attempting any work on or with the unit.
Warnings and Notes
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 crucialthan warnings,but
should not be disregarded.
Warnings Readers are informed of situations that can result in serious
physical injury and/or serious damage to equipment 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.

Safety Instructions
Notes Readers are notified of the need for special attention or additional
information available on the subject with the following symbols:
General Safety
Instructions
These safety instructions are intended for all work on the
ACS 300.
WARNING! All electrical installation and maintenance work on
the ACS 300 should be carried out by qualified electricians.
The ACS 300 and adjoining equipment must
always be properly
earthed.
The motor and all accessories must be earthed through
ACS 300.
All the ACS 300 units include capacitors connected between the
main circuit and the frame. These capacitors increase the earth
leakage current through the PE connector to the mains and may
cause some fault current circuit breakers to function.
Do not attempt any work on a powered ACS 300. After switching
off the mains, always allow the intermediate circuit capacitors 5
minutes to discharge before working on the frequency converter,
the motor or the motor cable. It is good practice to check (with a
voltage indicating instrument) that the frequency converter is in
fact unpowered before beginning work.
The ACS 300 motor cable terminals are at a dangerously high
CAUTION! Caution emphasises a matter in order to draw
special attention to it.
Note! Note gives additional information or points out
more information available on the subject.

Safety Instructions
voltage when mains power is applied regardless of motor
operation.
There can be dangerous voltages inside the ACS 300 from
external control circuits when the ACS 300 mains power is shut
off. Exercise appropriate care when working with the unit.
Negligence to these instructions can cause physical injury and
death.
WARNING! The ACS 300 may introduce electric motors, drive
train mechanisms and driven machines to an extended operating
range. It should be confirmed that all equipment is suitable for
these conditions.
All insulation tests must be carried out with the ACS 300
disconnected from the cabling. Operation outside the rated
capacities should not be attempted.
Negligence to these instructions can result in permanent damage
to the ACS 300.
WARNING! Certain parameter settings and external control
signals may cause the ACS 300 to start up automatically after an
input power failure.

vi ACS 300 User’s Manual
Safety Instructions
The motor rotational direction can be locked to forward only by
using the DIR parameter. See page 67 for more details.
Mechanical faults on the motor, power failure or other faults may
cause stoppages. Correcting the fault may cause the motor to
restart. Take all necessary precautions to ensure personnel
safety and to avoid damage to equipment and property before
motor restart.
A supply disconnecting device shall be installed in each supply,
by which the electric parts of ACS 300 can be separated from the
mains network during installation and maintenance work. Isolator
must be load switch type according to EN 60947-3 class B to
meet the European Union Directives or the type which switches
off the loaded circuit by means of auxiliary contact opening main
contacts of switch. The supply disconnecting device shall be
locked to open position while installation and maintenance work
is going on.
Emergency Stop
Devices
Emergency stop devices shall be installed at each operator
control station and at other operating stations where emergency
stop may be required. Pressing the Stop key on the ControlPanel
of ACS 300 does not generate an emergency stop of the motor
and does not separate the drive from dangerous potential.
