14.5 CONNECTION OF THE VACUUM GAUGE
N O T E !
When using the 19” control panels –S or –S1, the connection of the vacuum
gauge is possible. Otherwise the connection is closed by a blind cap.
Fo
r all versions, a tube connector 1/4” is available for connection of the vacuum gauge.

Open the diagonal FRP-housing

Mount the hose pipe or tube to the respective fitting (see drawings in the annex)

Close the diagonal FRP-housing
At the 19“ control panels –S or –S1 corresponding marked connectors for the vacuum gauge are pro-
vided at the rear of the unit.
14.6 ELECTRICAL CONNECTION
The temperature setting of the dilution probe SP2006- H… is made on the electronic controller e.g.
70304G.
W A R N I N G !
The incorrect mains voltage can destroy the unit. Check the type
plate for the correct voltage prior to connection!
The dilution probe must be mounted in such a way that touching
the live parts is excluded!
In any case, we recommend the use of temperature resistant ca-
bles!
The alarm contact for low temperature must be controlled!
In case of a low temperature alarm (failure of heating or sensor) the
dilution gas or bypass gas supply must be interrupted to avoid se-
rious damage of the dilution probe. We recommend to switch the
low temperature alarm on to external solenoid valves that provide
the above mentioned function!
N O T E !
For the erection of power installations with nominal voltages of up
to 1000V, the requirements of VDE 0100 and its associated stan-
dards and specifications must be observed.
A mains switch must be provided externally.
The supply circuit of the unit must be equipped with a fuse with the
correct rating (over current protection); the electrical details see
technical data.

Remove cover of the controller 70304G.

Insert the mains cable (min. 3 x 1,5 mm 2 ) through the cable gland and connect to the appropri-
ate terminals (1 = ground, 2 = N, 4 = L).

Insert the signal cable (low temperature alarm) through the cable gland and connect to the ap-
propriate terminals 11 and 12 (contact position T
u
shows alarm event).

Screw cover back in place.
