WARNING
Risk of injury due to electrical voltage!
Rated surge voltages above the permitted over-
voltage category can damage the insulation in the
device. This impairs the safety of the device. This
can result in serious injury or death.
·
Only use the device in environments which
comply with the permissible rated surge
voltage.
WARNING
Risk of injury due to electrical voltage!
Do not short-circuit secondary connections of volt-
age transformers! This can result in serious injury or
death.
·
Connect voltage transformers according to
their documentation!
·
Check your installation!
Grid systems and maximum rated voltages ac-
cording to DIN EN 61010-1/A1:
The device is suitable for voltage measurement in
TN and TT systems.
The voltage measurement function of the device
has the overvoltage category 600V CATII
I
(rated
surge voltage 6 kV).
WARNING
Disregard of the connection conditions of the
transformers to Janitza measurement devices
or their components can lead to injuries or even
death or to material damage!
·Do
not
use the outputs of the Janitza measure-
ment devices or their components for switching
protective devices or protective relays! Do
not
use “Transformers for protection purposes"
!
·For Janitza measurement devices and their
components use
only“Transformers for mea-
surement purposes"
which are suitable for the
energy monitoring of your system.
·Observe the information, regulations and limit
values in the use information on
“Transformers
for measuring purposes"
, specifically during
testing and commissioning of the Janitza mea-
surement device, the Janitza component and
your system.
