W A R N I N G !
Incorrect system voltage can damage the unit. When establishing
connections, check that the system voltage corresponds with the
voltage shown on the type plate!
N O T E !
For the erection of power installations with rated voltages up to
1000V, the requirements of VDE 0100 and relevant standards and
specifications must be observed!
The main circuit is equipped with a fuse corresponding to the
nominal current (over current protection); for electrical details see
technical data.
Connection to the supply takes place via the inlet connector for non-heating apparatus with 2 metres
connecting cable at the rear of the combustion air conditioning unit (X1, see circuit diagram in annex).
In the nine-pole subminiature connector at the rear of the combustion air conditioning unit, the
following options are available:

Under/Overtemperature alarm and pressure drop alarm (common alarm)

External control
N O T E !
The function of the combustion air conditioning unit is only
ensured when the Sub-D-Plug X2 is fitted !
Figure 3 shows the pin assignment in the Sub-D-Plug X2.
