7. Installation
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!
Use the measurement device for voltage mea-
surement in TN and TT grid systems with the ap-
proved overvoltage category of 300V CATII
I (rated
surge voltage 4 kV).

WARNING
Disregard of the connection conditions of the
transformers to Janitza measurement devic-
es or their components can lead to injuries or
even death or to material damage!
·Do not use Janitza measurement devices or
components for critical switching, control or
protection applications (protective relays)! It
is not permitted to use measured values or
measurement device outputs for critical appli-
cations!
·For Janitza measurement devices and their
components use
only“Transformers for mea-
surement purposes”
which are suitable for the
energy monitoring of your system. Do
not use
“Transformers for protection purposes”
!
·Observe the information, regulations and limit
values in the usage information on
“Transform-
ers for measuring purposes”
, specifically
during testing and commissioning of the Janitza
measurement device, the Janitza component
and your system.
