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 devices or components
(modules) only in the manner described in the
associated usage information.
·
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
The field of transformer technology groups the
totality of all devices that perform the function of a
current, voltage or measuring transformer together
as
sensors
.
In the usage information for our devices, modules
and components, the terms
current transformer,
voltage transformer or transformer
all refer to
sensors
.
A further distinction is made by the terms
CT (cur-
rent transformer)
and
LP-CT (low-power current
transformer)
:
The term "current transformer" is used for special
transformers for the primary-proportional conversion
of currents of large magnitudes to directly measur-
able, smaller current values.
In contrast, the term "LP current transformer"
(low-power current transformer) is used for special
transformers for the primary-proportional conversion
of currents of large magnitudes to directly measur-
able, smaller voltage values (low power).
Current transformers
and
LP current transform-
ers
provide safe galvanic isolation between the pri-
mary circuit and the measurement circuit due to their
design and their physical operating principle. For
Janitza measurement devices, modules and compo-
nents, use only
"transformers for measuring pur-
poses"
which are suitable for the energy monitoring
of your system! Observe the corresponding warning
notices (see Sect. “7.1 Current measurement with
the module” on p. 24)!
The UMG 801 basic device uses the term
"current
transformer"
only in the display for the configura-
tion of both
current transformers
and
LP current
transformers
.
