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 
for  indirect  or  consequential  damages  resulting  from  the  use  or 
application of this equipment.
The  examples  and  diagrams  in  this  manual  are  included  solely 
for  illustrative  purposes.    Because  of  the  many  variables  and 
requirements  associated  with  any  particular  installation,  Parker 
Hannifin  Corporation  cannot  assume  responsibility  or  liability  for 
actual use based on the examples and diagrams.
No patent liability is assumed by Parker Hannifin Corporation with

      •  Recognize the Consequence
 
SHOCK HAZARD
  Labels  may  be  located  on  or  inside  the 
equipment  to  alert  people  that  dangerous 
voltage may be present.
  BURN HAZARD  Labels  may  be  located  on  or  inside  the 
equipment to  alert  people that  surfaces may

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.
