5.  Generic Junction Box

The HUB-SDM5 can be used as a generic junction box.  In its default
configuration, six, five conductor cables can be connected to each other.
Three, ten conductor cables can be connected to each other by removing the
jumper between the terminal strips.  Use a small screwdriver to pry the jumper
out.

6.  Maintenance

There are no user-serviceable parts in the HUB-SDM5.  Make sure that all
unused bulkhead fittings are sealed with a plug and that the lid is tightly
fastened.
