ATTENTION
You may ground the cable shield at either end of the cable.
Do not ground the shield at both ends. Recommended
practice is to ground the cable shield at the terminal base
and not at the transducer. Any convenient Chassis terminal
may be used (see Terminal Block Assignments on page 18).
IMPORTANT
The internal transducer power supply is providing power to
the TTL device.
