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
(available online at www.parker.com/pneu/isysNet) 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 Hannifin Corporation be responsible or liable

Environment and Enclosure
This equipment is intended for use in overvoltage Category
II applications (as defined 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 difficulties 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 Specifications section of this publication.
Subsequent sections of this publication may contain additional
information regarding specific enclosure type ratings, beyond
what this product provides, that are required to comply with
certain product safety certifications.
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.

ATTENTION
Preventing Electrostatic Discharge
This equipment is sensitive to electrostatic discharge, which
can cause internal damage and affect normal operation. Follow
these guidelines when you handle this equipment:
• Touch a grounded object to discharge potential static.
• Wear an approved grounding wriststrap.
• Do not touch connectors or pins on component boards.
• Do not touch circuit components inside the equipment.
• If available, use a static-safe workstation.
• When not in use, store the equipment in appropriate static-
safe packaging.
