De-installing the Inverter
De-install the inverter and wire box assembly according to the following steps
when the inverter needs to be removed:
1.
Turn off the external AC breaker and/or system disconnect switch using
lock-out/tag-out procedures.
2.
Turn off the external DC breaker and/or disconnect switch, if present, and
use lock-out/tag-out procedures.
3.
Switch the
inverter’s AC disconnect switch to “OFF” position.
4.
Switch the
inverter’s DC disconnect switch to “OFF” position.
5. Wait for 5 minutes to ensure the internal capacitors have been
completely discharged.
6.
Measure the AC output conductor terminal voltage against the ground.
The meter should now read 0V.
7.
Disconnect the AC and PE cables referring to
“3.3.4 AC and ground
connection”.
8.
Disconnect the DC cables referring to “3.3.3 DC connection”.
Caution: if
PV strings terminate directly in the wiring box and do not pass
through a breaker or switch that was opened in Step 2 these strings
may be energized.
9.
De-install the inverter by reversing the installation steps found in section
3.2 Mechanical installation
.
DANGER:
Please disconnect the electrical connection in strict accordance with
the following steps. Otherwise, the inverter will be damaged and the
service personnel’s life will be endangered.
