Terminal Blocks
The RGU includes two terminal blocks which are available for customer
connections (TB1 and TB2, shown in Figure 4.14). These terminal blocks
are located in the leftmost bay of the unit.
The RGU also has an analog I/O terminal block available for customer
connections (TB1, on the main control board). Details for connecting,
programming, and using analog I/O can be found in publication

N-code RGUs also include an additional terminal block (TB3). This
terminal block is dedicated for motor-operated circuit breaker wiring.
