Installation and Connection
ATTENTION!
When arranging two or more inverters vertically, respect the minimum clearance A + B (figure 3.2)
and provide an air deflecting plate so that the heat rising up from the bottom inverter does not affect
the top inverter.
ATTENTION!
Provide conduit for physical separation of the signal, control, and power conductors (refer to item
3.2 - Electrical Installation).
