Installation of the SK TU2 technology unit
To install a technology unit, remove the 6 screws from the cover plate. Note the grounding (earthing) lead,
which is connected to the plate with a plug.
When installing the technology unit this lead must be connected in order to ensure complete grounding
(earthing).
Sealing for the maximum protection level
IP55/66 is only ensured by installing the seal
and correctly tightening the 6 screws.
The procedure for installation is identical for
the device series trio SK 300E and SK 750E.
For SK 750E the bus module must always be
installed in the right-hand technology slot.
Earthing line
Make sure the earthing line is plugged into the plate of
the standard device and each technology unit. This line
must be connected when installing the technology unit to
ensure it is fully earthed.
