10.1 Measured voltage / supply voltage
INFORMATION
In networks with nominal voltages that exceed the
specified nominal voltages of 300 VAC, connect
the voltage measurement inputs via voltage trans-
formers.
Connecting measured voltage / supply voltage:
1. Connect the measured voltage to the termi-
nals provided for this purpose on the device
(see section „7.3 Supply voltage“ on page
27 and section „7.4 Voltage measurement“
on page 28).
2. After connecting the measured voltage, check
the measured values measured by the device
(if necessary, via the GridVis software) for the
voltages L-N and L-L.
Take into account any voltage transformer
factors that may be set!

WARNING
Risk of injury due to electrical voltage!
If the device is exposed to surge voltages above
the permissible overvoltage category, safety-rele-
vant areas of insulation in the device can be dam-
aged. This means that the safety of the product
can no longer be guaranteed.
Only use the device in environments in which
the permissible overvoltage category is not
exceeded.
WARNING
Material damage due to disregard of the con-
nection instructions!
Voltages and currents outside the permissible
measuring range can destroy the device.
Comply with the measuring range specifica-
tions from the technical data.
INFORMATION
Before commissioning, delete any possible produc-
tion-related contents of the energy meters, mini-
mum and maximum values and records.
