Open the knockouts for wiring
CPS PV Inverter supports configurations of wiring from different directions
with conduits. For the knockouts, two different sizes can be used and the
diameter of these knockouts is shown in figure 6.4.2. Each knockout has two
different levels of opening area that can be used, inner level area and outer
level area, as figure 6.4.3 indicates.
