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, disconnec-
tion, grounding and marking of electrical equip-
ment.
·the requirements concerning personal protective
equipment.
Electrically qualified persons within the scope of the
technical safety information of all usage informa-
tion associated with the device and its components
(modules) 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
(modules)!
Opening, dismantling or unauthorized manipulation of
the device and its components (modules) 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 per-
mitted to work on the devices and their com-
ponents (modules), assemblies, systems and
current circuits.
·
Always use your device or component (module)
only in the manner described in the associated
documentation.
·
If there is discernible damage, send the device
or the component (module) back to the manu-
facturer!
2.6 Warranty in the event of damage
Any unauthorized tampering with or use of the
device, component or module constitutes “misuse”
and/or “negligence” under the product’s warranty
and thus voids the warranty for any possible re-
sulting damage. Note in this regard Sect. “3.3
Intended use” on p. 15
2.7 Safety information for handling current
transformers
Definition of the terms current transformers/cur-
rent sensors:
In this user manual, the term
"current transformer"
is used for special transformers for the proportional
conversion of currents of large amperages to directly
measurable, smaller
current values
.
In contrast, the term
"current sensor"
is used for
special transformers for the proportional conversion
of currents of large amperage to directly measurable,
smaller
voltage values
.
Current transformers and current sensors provide a
safe galvanic isolation between the primary circuit
and the measurement circuit due to their construc-
tive design and their physical operating principle.
For simplification, the UMG 801 basic device only
uses the term "current transformer" in the display
to configure "current transformers" and "current
sensors"!
WARNING
Risk of injury due to high currents and high elec-
trical voltages at the current transformers/current
sensors!
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 cur-
rent 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/current sensors
with basic insulation according 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/current sensor con-
nection on the device are tightened sufficiently!
·
Comply with the information and provisions in
the documentation of your current transform-
ers/current sensors!
