Before running my X1-boost inverter, what should I do?

Please check all below steps:
a) Check that device is fixed well on the wall.
b) Make sure all the DC breakers and AC breakers are disconnected.
c) AC cable is connected to grid correctly.
d) All PV panels are connected to inverter correctly, DC connectors which are
not used should be sealed by cover.
e) Turn on the external AC and DC connectors.
f) Turn on the DC switch to the “ON” position.
