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
• Prevent foreign dust, flecks, 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.
