2.1 Safety Symbols
The following symbols are used in this document:
WARNING
Indicates a potentially hazardous situation that could
result in death or serious injury.
CAUTION
Indicates a potentially hazardous situation that could
result in minor or moderate injury. It can also be used to
alert against unsafe practices.
NOTICE
Indicates important information, including situations that
can result in damage to equipment or property.
2.2 Qualified Personnel
The products may only be assembled, installed,
programmed, commissioned, maintained, and decommis-
sioned by persons with proven skills. Persons with proven
skills
•
are qualified electrical engineers, or persons who
have received training from qualified electrical
engineers and are suitably experienced to
operate devices, systems, plant and machinery in
accordance with the general standards and
guidelines for safety technology.
•
are familiar with the basic regulations concerning
health and safety/accident prevention.
•
have read and understood the safety guidelines
given in this manual and also the instructions
given in the operating instructions of the
frequency converter.
•
have a good knowledge of the generic and
specialist standards applicable to the specific
application.
Users of Power Drive Systems (Safety Related) (PDS(SR)) are
responsible for:
•
Hazard and risk analysis of the application.
•
Identifying safety functions required and
allocating SIL or PLr to each of the functions.
•
Other subsystems and the validity of signals and
commands from them.
•
Designing appropriate safety-related control
systems (hardware, software, parameterisation,
etc.).
Protective measures
•
Safety engineering systems may only be installed
and commissioned by qualified and skilled
personnel.
•
Install the frequency converter in an IP54 cabinet
as per IEC 60529 or in an equivalent environment.
In special applications, a higher IP degree may be
necessary.
•
Ensure short-circuit protection of the cable
between the safety option and the external safety
device according to ISO 13849-2 table D.4.When
external forces influence the motor axis (for
example suspended loads), additional measures
(for example a safety holding brake) are required
to eliminate hazards.
2.3 Safety Precautions
WARNING
HIGH VOLTAGE
Frequency converters contain high voltage when
connected to AC mains input, DC supply, or load sharing.
Failure to perform installation, start-up, and maintenance
by qualified personnel can result in death or serious
injury.
•
Installation, start-up, and maintenance must be
performed by qualified personnel only.
