12. Configuration
12.1 Connecting the supply voltage
To configure the device, connect the supply
voltage. Observe the general safety instructions
while doing so, as described in chap. „2. Safety“
on page 10.
The supply voltage level can be found on
the rating plate of the device or in chap. „18.
Technical data“ on page 58.
If no device display appears, check whether the
supply voltage is within the rated voltage range.
WARNING
Risk of injury or damage to the device due to
too high electric voltage!
Serious personal injuries up to death, or device
malfunctions up to destruction, can occur!
Therefore, please observe the following:
· Do not exceed the threshold values stated
in the user manual and on the rating
plate; this must also be observed during
inspection and commissioning.
· Safety instructions and warning notices in
the documents that accompany the devices
and their components!
NOTE
The device requires approximately 20 s to
determine the mains frequency. During this time
period, the assured measurement uncertainty
does not apply for measured values!
12.2 Programming mode
The device has a programming mode, in which 3
main settings can be programmed:
1.
Current transformer
2. Voltage transformer
3. Parameter lists (for setting ranges, see
chap. „18.2 Parameter and Modbus address
list“ on page 62).
Everything on the display mode and
programming mode can be found in chap.
„11. Operation and button functions“ on page
33.
12.3 Password protection
In order to hinder an accidental change of the
programming data, a user password can be
programmed. More detail in chap. „12.7.6 User
password
(parameter address 050)“ on page 39.
12.4 Current transformer and voltage
transformer
For the use of current transformers, configure
the current transformer ratio for your device if
necessary (standard setting: 5/5 A).
NOTE
For suitable operating values, do not set the
value 0 for the primary current transformer!
For the use of voltage transformers, configure
a voltage transformer ratio.
NOTE
Observe the specified measured voltage during
the connection of voltage transformers.
Configure the transformation ratio of the
respective group for the current measurement
inputs I1-I3 or voltage measurement inputs V1-V3.

NOTE
The transformation ratio of the current
transformer and voltage transformer can also be
configured via the GridVis
