KBR MWV measuring transducer adapter Introduction
Safety notes
In order to prevent operating errors, handling of the device has been kept as
simple as possible. This will enable you to use the device very quickly. Be sure to
carefully read the following safety notes.
DANGEROUS VOLTAGE
The applicable DIN/VDE regulations must be observed for installation!
Power supply connection, setup and operation of the device may only be
performed by qualied personnel. Qualied personnel as dened in the safety
notes in this user manual are personnel with electrical engineering qualica-
tions, knowledge of the national accident prevention regulations and safety
engineering standards as well as of the installation, commissioning and opera-
tion of the device.
To prevent re and electric shock, do not expose the device to rain or moisture!
Before connecting the device to the power supply, check whether the local
power supply conditions comply with the specications on the device name-
plate.
A faulty connection may result in the destruction of the device!
When connecting the device, ensure that the data given in the connection
chart is complied with (see "Connection diagram") and that the connection
cables are not live. When wiring, always ensure that all wiring material used is
neither damaged nor defective
and that the polarity is correct!
For proper and safe product operation, ensure that the device is transported,
stored, installed, assembled, and carefully operated and maintained in accor-
dance with the specications.
A visibly damaged device must generally be considered unt for use and dis-
connected from the power supply. Troubleshooting, repairs and maintenance
work may only be carried out in our facilities or after contacting our service
team.
Opening the device without authorization will render your warranty null and
void. Correct operation can no longer be guaranteed!
All input and output cables of systems that are at risk from lightning strikes must
be tted with lightning protection (see chapter "Protective measures" for recom-
mendations).

KBR MWV measuring transducer adapter
1 Application
With the measuring transducer adapters (zero-point creators), you can create a virtual
low-impedance neutral point for the measuring device in a three-phase network without
neutral conductor.
In the 600 or 700-V version, you can also use it to adapt the measuring voltage to the
measuring devices.
NOTE
Make sure that the measuring devices are congured for operation with a zero
point creator.
1.1 The following transducer types are available:
Type 400/100: Primary: 400 V phase-phase voltage IEC
Secondary: 100 V phase-phase voltage IEC
Type 600/86 Primary: 600 V phase-phase voltage UL (NRTL)
Secondary: 86 V phase-phase voltage UL (NRTL)
Type 700/100 Primary: 700 V phase-phase voltage IEC
Secondary: 100 V phase-phase voltage IEC
2 Installing the device
The housing of the transducer attachment is designed for mounting in the cabinet
to 35 mm standard rail. The module is snapped on the standard rail.
