User Manual Supplement
Important User Information
Solid-State equipment has operational characteristics differing from those of
electromechanical equipment.
“Safety Guidelines for the Application, Installation
and Maintenance of Solid-State Controls”
(Publication SGI-1.1) describes some
important differences between solid-state equipment and hard-wired
electromechanical devices. Because of this difference, and also because of the wide
variety of uses for solid-state equipment, all persons responsible for applying this
equipment must satisfy themselves that each intended application of this equipment
is acceptable.
In no event will Rockwell Automation be responsible or liable for indirect or
consequential damages resulting from the use or application of this equipment.

Installation
!
ATTENTION:
To guard against electrical shock, disconnect from
power source before installing or servicing.
!
ATTENTION:
Do not touch drive surfaces. Temperatures are hot
enough to cause severe burns.
!
ATTENTION:
After system installation, remove the debris label
from the unit. Failure to remove this label may result in overheating
or nuisance tripping.
