GeneralHandling

WARNING

Products are precision electronic devices. Do not attempt to disassemble or modify them as damage,

malfunctionorotherproblemscouldresult.

Immediatelystopoperationandtheturnpoweroffiftheproductsemitsmoke,strangeodor,orunusualnoise

orwhensomeotherabnormalordangerousconditionisdetected.Continuedusemayleadtosystem(hydraulic

equipment,mechanicalequipment)malfunction,fireorotherseriousaccidents.

Do not subject pressure switch to pressures beyond rated pressure.  Excessive pressures could damage or

breakthepressureelementandcauseinjuryand/ordestructionofsurroundings. 

Usingunspecifiedvoltagecouldcausefiresorelectricalshock. 

Donotsubjectproductstoexcessiveweight,vibrationorimpactthatcoulddamageorbreakproducts,cause

leakageofmeasurementmediumthatcanleadtoinjuryordamagetothesurroundings. 

Products are not explosion‐proof.  Do not use in hazardous areas where flammable or explosive gases or

liquidsmaybepresent. 

Performwiringcorrectlyaccordingtothewiringdiagramintheinstructionmanual.  Incorrectwiringcanresult

inproductfailureorfire. 

Usewithinoperatingtemperaturerange.  Useofproductsoutsidetheoperatingtemperaturerangecanlead

toproductfailureandcauseinjuryaswellasdamagetothesurroundings. 

Carryoutinstallationinaccordancewiththeinstructionmanual.

Theseprecisionelectronicdevicesshouldbekeptawayfromsourcesofelectricalnoise.  Usenoisefilters,etc.,

toreduceelectricalnoisefromthepowersourcestotheseproducts. 

Installation

WARNING

Donotattempttochangewiringorinsertordisconnecttheconnectorwhiletheproductsareenergizedasit

couldleadtoseriousaccidents.



CAUTION

When installing the pressure switch ina pressure line, do not install itwhile the lineisfilled with liquid.  As

liquid is incompressible, tightening the pressure fitting could generate high pressures that could damage the

pressureswitch.  Wheninstallingthepressureswitch,removeliquidfromthepressureline,leavingabout15to

20mmofairandthentightenthepressurefitting.  

Donotinsertwiresorothersharpobjectsintothepressureinletastheycoulddamagethediaphragmandaffect

normaloperationofthepressureswitch.
