1. Connect individual
input
wiring to numbered terminals on the 0–15
row (A) as indicated in the table below.
1.
Connect the associated input wiring to the corresponding odd numbered
terminal on row (A) (1794-TB2) or the associated terminal on row (C)
(1794-TB3) for each input as indicated in the table below. (Odd numbered
terminals on row A and terminals C-34 thru C-51 are internally connected
together.)
2. Connect 120V ac L1 to terminal 34 on the 34–51 row (C).
3. Connect 120V ac common L2 to terminal 16 on the 16–33 row (B).
4. If continuing power to the next terminal base unit, connect a jumper
from terminal 51 (120V ac L1) on this base unit to terminal 34 on the
next base unit.
5. If continuing common to the next terminal base unit, connect a jumper
from terminal 33 (120V ac common L2) on this base unit to terminal
16 on the next base unit.
