Wiring to a 1794ĆTB2, ĆTB3 or ĆTB3S Terminal Base Unit

WARNING

!

If you connect or disconnect wiring while the
fieldside power is on, an electrical arc can occur.
This could cause an explosion in hazardous location
installations. Be sure that power is removed or the
area is nonhazardous before proceeding.

1. Connect individual output wiring (customer loads) to even-numbered

terminals 0 through 14 on the 0 to 15 row (A).

2. Connect the associated return to the corresponding terminal on the

16–33 row (B) or to the odd-numbered terminals on the 0–15 row (A)
as indicated in the wiring table below. (Returns are internally
connected together.)

3. C24V dc power to terminal 34 on the 34–51 row (C).

4. If continuing power to the next terminal base unit, connect a jumper

from terminal 51 (+24V dc) on this base unit to terminal 34 on the
next base unit.

5. Connect 24V dc return to terminal 16 on the 16–33 row (B).

6. If continuing 24V return to the next terminal base unit, connect a

jumper from terminal 33 (return) on this base unit to terminal 16 on
the next base unit.
