Notes on installation
Expert installation under observation of the technical regulations for planning,
construction and operation of the system as a whole is the precondition for
faultless functioning of the contents indicator. These regulations also include
the accident prevention regulations of the employers‟ liability insurance
associations, the VDE regulations, and the installation and operating
instructions for the fluid tank. The housing of the indicator is suitable for wall
mounting and is connected to the 230 V mains supply. Under normal
circumstances, the indicator must be operated with the housing cover closed.
It is installed and commissioned by the qualified technician while the unit is
open.
Warning: Keep away from the area of the 230 V terminal.
Installation of the SmartBox
Mount the indicator to the wall in a suitable position. After loosening the four
screws, open the indicator by removing the cover. Mount the unit to a smooth
vertical wall by means of four dowels. Mount the housing of the indicator by
the four fixing holes by means of the enclosed screws. Take care not to
damage the housing! After connecting the terminals and setting the unit up,
re-screw the cover.
Warning: The indicator must not be installed in areas subject to explosion hazards!
Mounting of the probe
 For welded basement steel tanks and buried tanks,
the probe is installed by means of the enclosed screw
fitting with cable bushing.
 In most cases of installation to basement tanks,
the fuel gauge with float used before is dismounted so
that its opening can be used to screw in the probe unit.
 With buried tanks, there usually is a free opening to
screw in the probe element; it will be closed with a
removable filler plug.
Installation of the probe into the tank by means of
the enclosed screw fitting (see illustration):
