Chapter 1: Getting Started 3
Examination before Installation
Every SG2 smart relay has been fully tested and examined before shipment. Please carry out the following
examination procedures after unpacking your SG2 smart relay.
• Check to see if the model number of the SG2 matches the model number that you ordered.
• Check to see whether any damage occurred to the SG2 during shipment. Do not connect the SG2 smart relay to the
power supply if there is any sign of damage.
Contact
if you find any abnormal conditions as mentioned above.
Environmental Precautions
The installation site of the SG2 smart relay is very important. It relates directly to the functionality and the life
span of your SG2. 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 SG2 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 SG2 smart 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.
