There is a module inside the
lower control box, called a TBM
(Terminal Block Module) that
provides terminal point
connections for both positive and
ground circuits. A signal from the
Emergency Stop circuit activates
a load-reduction relay within the
TBM that provides ample power
to the B+ (positive) terminal strip.
This arrangement protects the
system against voltage drop
conditions that can be
detrimental to the electrical
system.
