4. Position the module (4) with its alignment bar (5) aligned with the
groove (6) on the terminal base.
5. Press firmly and evenly to seat the module in the terminal base unit. The
module is seated when the latching mechanism (7) is locked into
the module.
Connecting Wiring for your 1794-IM8 and 1794-OM8 Module
1. Connect individual input or output wiring to numbered terminals on
row (B) as indicated in the
Wiring Connections for 1794-IM8 and
1794-OM8
table.
2.
1794-IM8
– Connect the associated 220V AC L1 power lead of the
input device to the corresponding odd-numbered terminal (C-1, 3, 5, 7,
9, 11, 13, or 15) on row (C) for each input as indicated in the
Wiring
Connections for 1794-IM8 and 1794-OM8
table. (The 220V L1 power
terminals of row (C) are internally connected together.)
1794-OM8
– Connect the associated 220V AC common L2 lead of the
output device to the corresponding odd-numbered terminal (C-1, 3, 5,
7, 9, 11, 13, or 15) on row (C) as indicated in the
Wiring Connections
for 1794-IM8 and 1794-OM8
table. (The 220V L2 commons of odd-
numbered terminals on row (C) are internally connected together.)
3. Connect 220V AC power (L1) to terminal 34 on the row (C).
4. Connect 220V AC common (L2) to terminal 16 on the row (B).
5. If daisychaining L1 power to the next terminal base, connect a jumper
from terminal 51 (220V AC L1) on this base unit to terminal 34 on the
next base unit.
6. If continuing 220V AC common (L2) to the next base unit, connect a
jumper from terminal 33 (220V common L2) on this base unit to
terminal 16 on the next base unit.
