2.2 Qualified Personnel
The products must 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 PDS(SR) are responsible for:
•
Hazard and risk analysis of the application. In EN
ISO 12100, risk assessment is defined as an
overall process comprising a risk analysis and a
risk evaluation.
•
Ensuring that the qualified personnel has
experience with working in ATEX areas according
to Directive 99/92/EC (also known as the
ATEX
Workplace Directive ).
•
Identifying safety functions required, and
allocating SIL to each of the functions.
•
Other subsystems and the validity of signals and
commands from those subsystems.
•
Designing appropriate safety-related control
systems (hardware, software, parameterisation,
and so on).
Protective measures
•
Safety engineering systems must 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 terminal 37 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
EXPLOSION HAZARD
Using the VLT
®
PTC Thermistor Card MCB 112 in areas
with explosive gas and/or dust atmosphere may lead to
death, personal injury, or property damage. To avoid the
risk, adhere to the following:
•
Always provide the MCB 112 with a pressurised
enclosure according to EN 60079-1 (Explosive
atmospheres - Part 1: Equipment protection by
flameproof enclosures “d”).
•
Observe national safety rules and regulations
for prevention of accidents, as well as the
European Standard EN 60079-14 (Explosive
atmospheres - Part 14: Electrical installations
design, selection, and erection).
•
Only qualified personnel (see
chapter 2.2 Qualified Personnel ) is allowed to
install, connect, and commission the MCB 112.
•
Ensure that the motor thermal protection
switches off the motor directly, via the STO
function, or by using the ATEX ETR thermal
monitoring function.
