)
The SafeDC mode is now disabled and the voltage of each power optimizer equals the voltage of the
module (Voc).
WARNING:
The DC cables carry a high voltage and the
power o
ptimizers no longer output a safe 1V output.
PROCEED WITH CARE!

Step 7, Commissioning
Connect the strings to the inverter:

When connecting to SolarEdge inverters, or to non-SolarEdge inverters with SMI, perform the
Commissioning steps as described in the SolarEdge Inverter Installation Manual, or SolarEdge SMI
Installation Manual, available on the SolarEdge website at
http://www.solaredge.com/groups/support/downloads.
All the power optimizers must be logically paired to the inverter/SMI. The power optimizers do not
start producing power until they are paired with an inverter.

When connecting to non-SolarEdge inverters without SMI, pairing is not required. Perform the
Commissioning steps of the non-SolarEdge inverter as described in its manual.
