INSTALLATION
Part of the TDFI7800/TD7800 enclosure is constructed on Non-Metallic
material. To Prevent the risk of electrostatic sparking, the enclosure
shall only be cleaned with a damp cloth.The TR7800 Transducer is
designed for use with the TR Rack Kit. Physically, it is the same as
the TT7800 (Terminal Block) Unit except that the terminal block has
been rotated to the rear. For more information, see Figure 6. “TR7800
Outline Dimensions”.
NOTE:
The Model T7800 can be mounted directly onto a flat surface
using two 10-32 Screws. For more information, see Figure 2.
“TA7800 Outline Dimensions”.
The Model T7800 is supplied with a Mounting Kit 16799-1 for
Panel or Wall Mounting and a Mounting Bracket Kit 16893 for Din
Rail Mounting. For more information, see Figure 3 and Figure 7.
An Optional Mounting Kit 19254-1 is available when installing the
