• Run the Main AC Cable through a knockout on the BBU into the BBU for connection. It is
recommended to use a 1/2” knockout for ease of installation. The cable can run through a conduit
from a hardwired dedicated branch circuit to the BBU as shown in Figure 42. If using conduit, a liquid
tight conduit connector, as shown in Figure 38, must be installed to maintain the UL50E NEMA 4
rating for waterproofing. This connector is not included and must be provided by the installer.
• Alternatively, the AC Cable can be free wired between a dedicated branch circuit to the BBU
knockout if permitted by the AHJ. If you are free wiring the AC Cable, you must do so using the
provided 1/2” liquid tight cable gland to maintain the UL50E NEMA 4 rating for waterproofing. This
cable gland is included and is shown in Figure 39.
Note: Follow your local code requirements.
