!
WARNING: Personal injury may result from improper operation.
CAUTION: The iSmart relay may be damaged by improper operation.
Installation Precautions
!Compliance with the installation instructions and the user manual is absolutely necessary. Failure to comply could lead to improper operation,
equipment damage or in extreme cases even death, serious bodily injury or considerable damage to property.
!When installing the open-board models, insure that no wiring or foreign materials can fall into the exposed circuits and components.
Damagetoequipment,re,orconsiderabledamagetopropertycouldresult.
!Alwaysswitchopowerbeforeyouwire,connect,install,orremoveanymodule.
!The wiring for the iSmart relay is open and exposed. For the open-board models, all electrical components are exposed. It is recommended the iSmart
relay be installed in an enclosure or cabinet to prevent accidental contact or exposure to the electrical circuits and components.
Neverinstalltheproductinanenvironmentbeyondthelimitsspeciedinthisusermanualsuchashightemperature,humidity,dust,corrosivegas,
vibration, etc.
!
Wiring Precautions
!Improper wiring and installation could lead to death, serious bodily injury or considerable damage to property.
TheiSmartrelayshouldonlybeinstalledandwiredbyproperlyexperiencedandcertiedpersonnel.
!
Make sure the wiring of the iSmart relay meets all applicable regulations and codes including local and national standards and codes.
!
Be sure to properly size cables for the required current rating.
!
Always separate AC wiring, DC wiring with high-frequency switching cycles, and low-voltage signal wiring.
!
Operation Precautions
!To insure safety with the application of the iSmart relay, complete functional and safety testing must be conducted. Only run the iSmart after all
testingandconrmingsafeandproperoperationiscomplete.Anypotentialfaultsintheapplicationshouldbeincludedinthetesting.Failuretodo
so could lead to improper operation, equipment damage or in extreme cases even Death, serious bodily injury or considerable damage to property.
!When the power is on, never contact the terminals, exposed conductors or electrical components. Failure to comply could lead to improper operation,
equipment damage or in extreme cases even death, serious bodily injury or considerable damage to property.
It is strongly recommended to add safety protection such as an emergency stop and external interlock circuit in case the iSmart relay operation must
be shut down immediately.
!
Pre-Installation Examination
Every iSmart relay has been fully tested and examined before shipment. Please complete the following examination procedures after unpacking your iSmart.
• Check to see if the model number of the iSmart matches the model number that you ordered.
• Check to see whether any damage occurred to the iSmart during shipment. Do not connect the iSmart relay to thepower supply if there is any sign of
damage.
Contact IMO Precision Controls Ltd if you nd any abnormal conditions as mentioned above.
Environmental Precautions
The installation site of the ISmart relay is very important. It relates directly to the functionality and the life span of your ISMART. Please carefully choose an
installation site that meets the following requirements:
• Mount the unit vertically
• Environmenttemperature:-4°F-131°F(-20°C-55°C)
• Avoid placing ISMART close to any heating equipment
• Avoid dripping water, condensation, or humid environment
• Avoid direct sunlight
• Avoid oil, grease, and gas
• Avoid contact with corrosive gases and liquids
5

• Preventforeigndust,ecks,ormetalscrapsfromcontactingtheiSmartrelay
• Avoid electric-magnetic interference (soldering or power machinery)
• Avoid excessive vibration; if vibration cannot be avoided, an anti-rattle mounting device should be installed to reduce vibration
