The device can be used in
·TN and TT networks,
·Residential and industrial sectors.
WARNING
Risk of injury due to electric voltage!
Measurement voltage surges over the approved
overvoltage category can damage insulation
in the device. The safety of the device will be
impaired. This can result in serious personal
injuries or death.
· Only use the device in environments in
which the permissible measurement
voltage surge can be observed.
· Observe the threshold values specified in
the user manual and on the rating plate.

6. Network systems
Use the device for voltage measurement in TN
and TT systems with the approved overvoltage
category of 300 V CAT III (measurement voltage
surge 4 kV).
In network systems with a neutral conductor N,
the measured values which require an N relate to
a calculated N.
WARNING
Risk of injury due to electric voltage!
Short circuited connections of voltage
transformers on the secondary side can result
in serious personal injuries or death.
· Do not short circuit secondary sides of
voltage transformers!
· Connect voltage transformers according to
their documentation! Check the installation!
