Correct Use ● Installation ● Coil Voltage Reduction (Holding Voltage) after Relay Operation • If the coil voltage is reduced to the holding voltage after Relay operation, first apply the rated voltage to the coil for at least 100 ms. • A voltage of at least 37.5% of the rated voltage is required for the coil holding voltage. Do not allow voltage fluctuations to cause the coil holding voltage to fall below this level. • If you use the Relay at the holding voltage, install a diode in parallel with the coil. The G7L-PV has no coil polarity. Connect the diode so that the polarity is the opposite of the applied coil voltage. Diode Selection ● Micro Loads • The G7L-PV is a Power Relay that is suitable for grid connection switching applications for inverters in photovoltaic power systems. Do not use the G7L-PV to switch minute loads, such as signals. ● Soldering PCB Terminals • Do not perform automatic soldering. Always solder the terminals manually. • Solder with the following conditions: Soldering iron temperature (max.) 380°C, Soldering time within 10 seconds. • The G7L-PV is not sealed. Do not wash the G7L-PV with water or detergent. G7L • Dielectric strength = VRM × Rated voltage × 2 • Forward current = IF ≥ Rated current ● PCB Mounting Interval (at Rated Coil Voltage) • If you mount more than one G7L-PV, maintain the mounting intervals that are given in the following figures. • If the Relays are used with the coil voltage at the holding voltage (37.5%) at an ambient temperature of 85°C, side-byside mounting (0 mm) is possible. Relay Mounting Direction Ambient operating temperature of 85°C: 30 mm min. Ambient operating temperature of 70°C: 0 mm min. Relay Mounting Direction Ambient operating temperature of 85°C: 40 mm min. Ambient operating temperature of 70°C: 0 mm min. 3 G 7 L P V - • Install the Relays in locations that are as dry as possible and have as little dust, dirt, and harmful gas as possible. • Using the a Relay under high temperature, high humidity, or harmful gas may deteriorate its performance characteristics due to condensation or corrosive materials, resulting in failure or burn damage to the Relay. • The Relay weight approx. 100 g. Be sure that the PCB is strong enough to support it. We recommend dual-side through-hole PCBs to reduce solder cracking from heat stress. • Install the Relay so that the surface with the markings faces up. (The coil terminals will be at the top and the contact terminals will be at the bottom.) G7L-PV PCB Power Relay - G 7 L P V • Application examples provided in this document are for reference only.
