Installation and Interconnections
The instrument is designed to be panel mounted, and is a standard 96x48mm panel meter
enclosure. Note that the instrument must always be situated in such a way as to enable
adequate air circulation about the unit.
If a transducer was supplied with the CCD100 a suitable cable may have been included.

Not Connected
If the transducer is being powered from another source (e.g. a mains powered supply) it
will only be necessary to connect to the two signal pins.
Note: The CCD100 has a fully floating differential input. For single ended use (i.e.
tranducers with differential output) join 0V (pin5) & Signal Return (pin12) at the transducer.
Ensure the common mode input range is not exceeded.
