General product description
The MBS Rogowski current transformer FASK in combination with the transducer ROI-3 is used for current measure-
ment of AC currents and is primarily used for retrofitting existing systems - either on busbars or on power cables.
Subsequent installation around the current conductor is possible because you can open the FASK sensor. The output
signal of the FASK sensor goes to the transducer ROI-3, which generates an AC current of 1 A at the output. The
transducer ROI-3 is available with different transmission ratios up to a maximum of 10 kA at 1 A.
Measuring of 50 Hz alternating currents up to 10 kA (FASK in combination with the transducer ROI-3)
The output signals of the FASK sensor are connected to the transducer ROI-3.
Safety information
Only qualified electrical specialists are permitted to install, put into operation, maintain and operate the de-
vice.
During all work on the device comply with the national health, safety and accident prevention regulations.
If you do not observe the safety regulations, this can result in death, serious physical injuries or extensive
property damage.
During set-up and operation, observe the applicable provisions and safety regulations (also national safety
regulations), as well as standard engineering practice.
Observe the installation instructions provided!
De-energise the system before starting the work. Check that it is de-energised!
De-energise the device before starting the work. Check that it is de-energised!
The safety-related data can be found in this document and the certificates (EC type approval certificate, if
applicable any further approvals).
Do not exceed the threshold values specified in the operation manual and on the rating plate.
Install the device in an appropriate enclosure with suitable protection type in accordance with IEC 60529 to
protect against mechanical or electrical damage.
Do not exceed the threshold values specified in the operation manual and on the rating plate.
Never operate equipment and current transformer circuits whilst open.
It is prohibited to open or modify the device. Do not repair the device yourself, but rather replace it with an
equivalent device.
Repairs must be carried out by the manufacturer only. The manufacturer shall not be liable for damage due to
violations.
The prerequisites for faultless, safe operation of the device are proper transport and proper storage, set-up
and installation, as well as operation and maintenance.
Only use accessories that comply with the specifications of the device manufacturer (e.g. combination of
FASK current transformer and ROI-3 measurement transducer).
Store the product documentation.
Do not use outdoors!
