The SMI Internal Interfaces
As part of the installation and configuration process, accessing the internal
components of the SMI may be required. This involves removing the cover of the SMI.
Opening and Closing the SMI Cover
To remove the SMI cover:
1. Turn the ON/OFF switch to OFF.
2. Disconnect the power to the SMI:
a. Turn OFF the inverter
b. Turn OFF the PSU. Wait 5 minutes for the inverter and SMI capacitors to
discharge.
3. Open the cover’s six Allen screws and carefully remove the cover.
CAUTION!
When removing the cover, make sure not to damage internal components.
SolarEdge will not be held responsible for any components damaged as a
result of incautious cover removal.
To close the SMI cover:
Attach the cover and secure it by tightening the screws with a torque of 4.0 N*m/ 2.9
lb*ft. For proper sealing, first tighten the corner screws and then the two central screws.
