Appendix D: SafeDC™
When AC supply to the inverter is shut off (by shutting off the AC breaker at the site), or
when the inverter ON/OFF/P switch is turned to OFF, the DC Voltage drops to a safe
Voltage of 1V per Power Optimizer.
The SolarEdge inverters are certified for compliance with the following standards as
disconnection devices for PV generators, meaning that they can replace a DC
disconnect:
IEC 60947-3:1999 + Corrigendum: 1999 + A1:2001 + Corrigendum 1:2001 + A2:2005;
DIN EN 60947-3
VDE 0660-107:2006-03
IEC 60364-7-712:2002-05
DIN VDE 0100-712:2006-06.
In compliance with these standards, follow the instructions below to disconnect the DC
power:
1.
Move the Connection Unit safety switch to the OFF position, as shown in the
following image.
2.
Move the inverter ON/OFF/P switch to OFF (0), as shown in
Appendix D
.
3. Disconnect the AC to the inverter by turning OFF the circuit breakers on the
distribution panel.
