Unpacking

1. While unpacking the Logix 500 positioner, check
the packing list against the materials received. Lists
describing the system and accessories are included
in each shipping container.
WARNING: When lifting a valve/actuator
assembly with lifting straps, be aware the
center of gravity may be above the lifting
point. Therefore, support must be given to
prevent the valve/actuator from rotating.
Failure to do so can cause serious injury to
personnel or damage to nearby equipment.

per immediately.
