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.

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.
