Installation
Typically, a positioner is shipped with the actuator. If
so, the factory mounts and calibrates the positioner
and connects the positioner to actuator tubing. If the
positioner is ordered separately from the actuator,
perform the appropriate mounting procedure. Refer
to the appropriate instruction manuals for actuator
and valve installation procedures.
WARNING
Always wear protective clothing,
gloves, and eyewear when performing
any Installation procedures to avoid
personal injury.
If installing into an existing
application, also refer to the WARNING
at the beginning of the Maintenance
section in this instruction manual.
Check with your process or safety
engineer for any additional measures
that must be taken to protect against
process media.

Certain nameplates may carry more than one
