Wire the 1756-IH16ISOE Module
You can only connect wiring to your module with an RTB or IFM.
After completing field-side wiring, secure the wires in the strain relief
area with a cable-tie.
WARNING
If you connect or disconnect wiring while the field-side 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.

Isolated wiring
1.
All terminals with the same name are connected together on the module. For
example, DC (-) can be connected to either terminal marked GND-15.
2.
When you use the second GND-15 terminal to daisy chain to other RTBs, always
connect the daisy chain to the terminal directly connected to the supply wire, as
shown in the example above.
3.
If separate power sources are used, do not exceed the specified isolation voltage.
4.
Do not connect more than 2 wires to any single terminal.
5.
The jumper bar is part number 97739201; use this number to order additional bars.
