Installation Guidelines and Best Practices

To maximize the performance and lifespan of your G2RV-ST700 relay:

• Use appropriate PCB soldering techniques (recommended: 260°C max for 5 seconds)
• Maintain minimum 2mm clearance between adjacent relays for proper heat dissipation
• For inductive loads (contactors, solenoids), implement appropriate arc suppression (RC networks or varistors)
• Do not exceed maximum switching ratings - consider derating for capacitive loads or high inrush currents
• Store in original packaging in environments below 40°C and 70% RH when not in immediate use
• Periodically inspect contacts in high-cycle applications (consider contact resistance measurement after 50,000 operations)
