the operating reliability of the device.
• Your device has been quality controlled, te-
sted and is ready for use. Please respect all
warnings and information which are marked

2. Identification
Please check particular type of unit and type
number from the identification plate. Type num-
ber and the corresponding execution are indica-
ted in the delivery documentation.
3. Installation
The unit should be used only according to the
protection level provided. Protect SGI/SGW, if
necessary, against environmental influences
such as sprayed water, dust, knocks, extreme
temperatures.
The wire actuated transmitter is a high quality
measuring device and should be mounted to a
flat surface (fig. 1).
• Remove the transport safety wire (1).
• Use the two through holes for fixing the unit to
the mounting surface (2).

Extend the wire up to the fixing point, ensuring it
is aligned and is not twisted. Tighten the lock nut
to fix the wire connector.
Attention: The overall length of the measuring
range + lead length must not exceed the maxi-
mum extension length.
Wire handling
To avoid damage to the wire outlet and to ensure
the unit's maximum life, the wire must be exten-
ded co-axially to the wire outlet (fig. 2).
Avoid sudden release of the wire when it is
extended as this will lead to incorrect rewind and
entanglements with subsequent wire breakage.
The wire should aways be under tension when it
is extended.
For correction function the wire must remain
without kinks or flattening.
Extension wire (accessory)
If necessary an extension wire can be used.
Attention: By using an extension wire the maxi-
mum measuring length can not be altered. Make
sure that the maximum extension length is not
exceeded.
