Installation
FASK-Current sensor
The installation of these sensors is very easy. In a few simple steps, the coil is placed around the primary conductor
and closed at the lock. The primary conductor does not have to be disconnected.
To open the FASK Rogowski current transformer, turn the bayonet catch to the left (unlock measuring line).
(Fig. 2)
Pull the coil line out of the housing. (Fig. 3)
Guide the coil cable around the power rail. (Fig. 3)
Slide the coil cable into the enclosure. (Fig. 4)
Turn the bayonet catch to the right until the end of the measuring coil audibly latches.
Make sure that the measuring coil does not touch the power rail that is to be measured or a neighbouring rail,
because the maximum permissible temperature of the signal line is +80 °C.
Connect the signal line of the FASK Rogowski current transformer to the input terminals of the measurement
transducer ROI-3.
Secure the FASK Rogowski current transformer to the primary conductor. To do so, guide a cable tie through
the intended fixture on the enclosure of the current transformer.

The direction of the primary cur-
rent is shown as an arrow on the
black plastic fastener. This direc-
tion of current must be considered
during installation.
A cable tie can be used to fix the
coil to the primary conductor.
Please pay attention here to the
appropriate temperature range.
