Matrix Module (inside Upper Control Box)
Terminal Block Module
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.
