2.5.15 MS 110 / MS 111 installation kit
MS 110 without additional 24 V supply
Sometimes limited space prevents the control
and inverter system from being mounted in the
same row in a machine’s electrical cabinet,
meaning that they must be mounted in two
separate rows. In other cases the design calls for
a second electrical cabinet to house the inverter
system. This means that the distribution and
arrangement of the components can be very
different from case to case.
In order to establish an electrical connection
(immune to noise) between the components of
the inverter system, the MS 1xx installation kits
are needed.
In most cases the additional 24 V are not needed,
since the UVR 1xxD provides enough current for
the fans and the MS 110 is sufficient.

MS 111 with 24 V supply
For inverter systems with many powerful UM
1xxD power modules, it might be the case that
the current provided by the UV(R) 1xx power
supply unit for the fans of the UMs does not
suffice to guarantee safe and reliable operation of
the fans.
If it is exceeded, then an MS 111 must be used in
the inverter row where the current consumption
is very high.
