Information: If aluminum conductors are being used, CPS
recommends the following steps to prepare each conductor prior
to landing and terminating to the AC terminal block:
1. Strip the outer insulating jacket from the conductor and use care so
as not to nick any of the strands.
2. Using a utility knife, gently strip the top layer of the aluminum
conductors
Figure 3-38 Preparing Aluminum Conductors prior to connecting
3. After removing the oxidized layer immediately apply neutral
grease (Noalox or an acid-and alkali-free Vaseline) and
immediately connect the cable lug to the conductor. Perform
these steps on one conductor at a time. If the process is stopped
or delayed before applying the grease, and continued later the
conductor must be scraped again. It takes roughly 30-60 seconds
for an oxidized layer to form on top of the conductors.
When the output of the inverter is connected to the grid, an external AC
circuit breaker is required to be installed to safely disconnect the inverter
from the grid should an over current event occur.
