2.5 Electrically qualified personnel
To avoid bodily injury and material damage, only
electrically qualified personnel are permitted
to work on the devices and their components,
modules, assemblies, systems and current circuits
who have knowledge of:
·the national and international accident prevention
regulations,
·safety technology standards,
·installation, commissioning, operation,
disconnection, grounding and marking of
electrical equipment,
·the requirements concerning personal protective
equipment.
Electrically qualified persons within the scope of
the technical safety information of all documents
associated with the device and its components are
persons who can furnish proof of qualification as
an electrically skilled person.
WARNING
Warning against unauthorized manipulation or
improper use of the device or its components!
Opening, dismantling or unauthorized manipulation
of the device and its components which goes
beyond the mechanical, electrical or other
operating limits indicated can lead to material
damage or injury, up to and including death.
· Only electrically qualified personnel are
permitted to work on the devices and their
components, assemblies, systems and
current circuits.
· Always use your device or component only
in the manner described in the associated
documentation.
· If there is discernable damage, send the
device or the component back to the
manufacturer!
2.6 Warranty in the event of damage
Any unauthorized tampering with or use of the
device constitutes "misuse" and/or "negligence"
under the product’s warranty and thus voids the
warranty of any possible resulting damage. In this
regard, please take note of chap. „3.3 Intended
use“ on page 17.
2.7 Safety information for handling current
transformers and measurement devic-
es with residual current measurement
WARNING
Risk of injury due to large currents and high
electrical voltage on the current transformers!
Current transformers operated while open on the
secondary side (high voltage peaks pose a hazard
when touched) can result in severe bodily injury or
death.
· Avoid operating the current transformers
while open; short circuit the unloaded
transformers!
· Before interrupting the current supply,
short circuit the secondary connections of
the current transformers. Switch any test
switches that automatically short circuit the
secondary lines of the current transformers
to the “Test” status (Check the test switch/
short circuiting connection beforehand)!
· Only use current transformers with basic
insulation to IEC 61010-1:2010!
· Caution, even current transformers rated as
safe for open operation can pose a hazard
when touched during operation while open!
· Make sure that screw terminals for the
current transformer connection on the device
are adequately tightened!
· Comply with the information and provisions
in the documentation of your current
transformers!
CAUTION
Risk of injury or damage to the meter due to
high measurement currents at the connections
of the current transformers!
High measurement currents can cause
temperatures of up to 80 °C (176 °F) on the
connections of the current transformers
· Use wiring that is designed for an operating
temperature of at least 80 °C (176 °F)!
· The current transformers can be hot even
after the power supply has been switched
off. Allow the connections of the current
transformers and the connecting cables to
cool down before touching them!
CAUTION
Risk of injury or damage to the meter due to
improper use!
Meters with residual current measurement can
trigger warning pulses if limit values are exceeded,
and these are used exclusively for monitoring
differential currents or failure monitoring. Use of
the warning pulses as a stand-alone protective
device against electrical shock can lead to injury or
damage to the device or your system!
·
Do not use devices with residual current
measurement as a stand-alone protective
device. Employ suitable protective devices for
your system!
