Wiring
Mount the control box with 4 appropriate fasteners on a vertical surface, above components
containing water, with the wire grommets down, and central to the other system components.
Make sure the cables will reach all of the modules to avoid splices. The main power feed
should come from an appropriately-sized fuse or breaker on the main DC panel. See wire size
and fuse/breaker tables below.
Warning! Do not connect the main power feed until all other connections are made.
