The E-BUS Terminal Blocks TB1 and TB2 provide an alternate method
of connecting the E-BUS Distribution Module to the other modules. This
method is used when it is necessary to pull the wire through conduit or
to extend the length.

WARNING: Power down the E-BUS Distribution Module

and E-BUS Module(s) before splicing the

HSSC

cable.
