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 E116P available online at www.parker.com/pneu/hseries
fi eldbus) 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 Parker Pneumatic Division be responsible or liable
for indirect or consequential damages resulting from the use or
application of this equipment.

Environment and Enclosure
This equipment is intended for use in overvoltage Category II
applications (as defi ned in IEC publication 60664-1), at altitudes
up to 2000 meters without derating.
This equipment is considered Group 1, Class A industrial
equipment according to IEC/CISPR Publication 11. Without
appropriate precautions, there may be potential diffi culties
ensuring electromagnetic compatibility in other environments
due to conducted as well as radiated disturbance.
This equipment is supplied as “enclosed” equipment. It should
not require additional system enclosure when used in locations
consistent with the enclosure type ratings stated in the
Specifi cations section of this publication. Subsequent sections
of this publication may contain additional information regarding
specifi c enclosure type ratings, beyond what this product
provides, that are required to comply with certain product safety
certifi cations.
NOTE: See NEMA Standards publication 250 and IEC
publication 60529, as applicable, for explanations of the degrees
of protection provided by different types of enclosure. Also,
see the appropriate sections in this publication, as well as the
publication E115P (“Industrial Automation Wiring and Grounding
Guidelines”), for additional installation requirements pertaining
to this equipment.
