The device is intended for:
• measuring and calculating electrical
variables such as voltage, current, power,
energy, harmonics, in building installations,
on distribution units, circuit breakers and
busbar trunking systems.
• measuring measured voltages and currents
that derive from the same network.
• measurements in low voltage networks
where rated voltages of up to 300 V phase
to earth and surge voltages of overvoltage
category III can occur.
• installation in fixed switching cabinets
or small installation distributors. It can
therefore be installed in any position.
• measurements in medium and high-
voltage networks with current and voltage
transformers.
• current measurement via external ../1 A
or ../5 A current transformers.
The measurement results can be displayed,
read out and further processed via the
device's interfaces.
The device meets the test requirements for
use in industrial areas.
4. 1
Measuring process
The device measures continuously and
calculates all effective values over a 200 ms
interval.
4. 2
Network failure detection
Network failure detection is carried out via the
voltage measurement inputs. The selection
of voltage measurement inputs can be
configured using the GridVis® software.
The device bridges the following network
failures on the auxiliary voltage input:
• Supply voltage:
230 V AC
• Bridging time:
max. 80 ms

NOTE!
Use the parameter list from “17.
Parameter list” for configuration
on the device and use the Modbus
address list on www.janitza.de for
configuration via a serial interface

Usage concept
You can program and call up the measured
values via many routes using the device:
•
Directly
on the device via 2 buttons and
the display.
• Using the
GridVis®
programming
software.
• Using the
device homepage
.
• Using the
Modbus protocol
. You can
modify and call up the data using the
Modbus address list. The list can be called
up from
www.janitza.de
.
This operation manual only describes how
to operate the device using the 2 buttons.
The GridVis® programming software has its
own "online help" system.
4. 4
GridVis® network analysis software
You can use the GridVis® network analysis
software that is available at www.janitza.de to
program the device and read out data. To do
this, a PC must be connected to the device
via a serial interface (RS485/Ethernet).
You can use the GridVis® network analysis
software to:
• program the device.
• configure and read out recordings.
• save the data to a database.
• display measured values graphically.
• program customer-specific applications.
