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. In this regard, please take note of
section „3.3 Intended use“ on page 19.
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 togeth-
er 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" is used for special trans-
formers for the primary-proportional conversion of
currents of large magnitudes to directly measurable
voltage values (low power).
Current transformers and LP current transform-
ers provide safe galvanic isolation between the
primary circuit and the measurement circuit due to
their design and their physical operating principle.
For Janitza measurement devices, modules and
components, use only "transformers for measur-
ing purposes" which are suitable for the energy
monitoring of your system! Please note Sect. “3.10
Transformers” on p.22 and Sect. “7. Installation”
on p.34 in this regard!
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.

www.janitza.com UMG801

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 basic device (mod-
ule) and/or your system due to a short circuit!
Inadequate insulation at the current measurement in-
puts of the modules with respect to the supply circuits
of the basic device can cause dangerous voltages
at the measurement input or damage to your device
(module)/system.
· Ensure reinforced or double insulation with
respect tothe supply circuits!
WARNING
Risk of injury due to large currents and high elec-
trical 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 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 with basic insu-
lation 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 ade-
quately tightened!
· Comply with the information and provisions in
the documentation of your current transform-
ers!
2.8 Safety information for handling measure-
ment devices with residual current mea-
surement
WARNING
Risk of injury or damage to the meter due to im-
proper use!
Meters with residual current measurement can trigger
warning pulses if limit values are exceeded, and these
are used exclusively for monitoring residual currents
or failure monitoring. Use of the warning pulses as a
stand-alone protective device against electrical shock
can lead to injury and even death!
· Do not use devices with residual current mea-
surement as a stand-alone protective device.
Employ suitable protective devices for your
system!
CAUTION
Risk of injury or damage to the meter/your system
due to short circuit!
Inadequate insulation of the operating equipment at
the residual current measurement input with respect
to the supply circuits can cause voltages at the
measurement input which represent a hazard when
touched or damage to your device or system.
· Ensure reinforced or double insulation with
respect tothe supply circuits!
· Ensure galvanic isolation of the residual current
measurement inputs from each other!
2.9 Handling batteries/accumulators
The following apply for the battery used in the de-
vice:
CAUTION
Risk of injury due to fire or burns!
The battery used in the device may cause fire or
burns if used improperly.
· Only replace the battery with the same type or
types recommended by Janitza!
· Observe the polarity when installing the bat-
tery!
· Remove batteries only with non-conductive
tools (e.g. plastic tweezers)!
· Do not recharge, disassemble, burn or heat
batteries above 100°C (212°F)!
· Do not dispose of batteries with household
waste! Follow the disposal instructions in the
respective device documentation!
