Chapter 2: Installing the Power Optimizer 19
Position the power optimizer close enough to its module so that their cables can be
connected.
Make sure to use power optimizers that have the required output conductor length.
Completely shaded modules may cause their power optimizers to temporarily shut
down. This will not affect the performance of the other power optimizers in the
string, as long as the minimum number of unshaded power optimizers connected in
a string of modules is met. If under typical conditions fewer than the minimum
power optimizers are connected to unshaded modules, add more power optimizers
to the string.
Equipment grounding tightening torques: 4-6 AWG: 45 lb-in, 8 AWG: 40 lb-in, 10-14
AWG: 35 lb-in.
To allow for heat dissipation, maintain clearance as specified below.

When installing modules in a confined space, for example, if installing Building-
integrated photovoltaic (BIPV) modules, ventilation measures may be needed to
ensure the power optimizers are not be exposed to temperatures outside their
specifications.
