Wire the Module

You can only connect wiring to your module through an RTB or IFM.

The example below shows how to wire the module.

After completing field-side wiring, secure the wires in the strain relief

area with a cable-tie.

Non-isolated

wiring

Isolated wiring

1. All terminals with the same name are connected together on the module. For

example, L1 can be connected to either terminal marked L1-15.

2. When daisy chaining the second L1-15 terminal to other RTBs, always connect the

daisy chain to the terminal directly connected to the supply wire, as shown in the

example above. Do not connect more than 2 wires to any single terminal.

3. If separate power sources are used, do not exceed the specified isolation voltage.

Assemble the Removable Terminal Block and the Housing

Install the Removable Terminal Block onto the Module

Before installing the RTB, make certain:

field-side wiring of the RTB has been completed.

the RTB housing is snapped in place on the RTB.

the RTB housing is closed.

the locking tab at the top of the module is unlocked.

!

WARNING When you connect or disconnect the Removable Terminal Block

(RTB) with field side power applied, 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.

Check the Indicators

The indicators show individual I/O status (yellow) for each point and

a bi-colored LED for module "OK" (red/green).

During power up, an indicator test is done and the following occurs:

"OK" indicator turns red for 1 second and then turns to

flashing green if it has passed the self-test.

I/O status indicators turn ON for a maximum of 2 seconds and

then turn OFF.

This completes installation of the module. Use the following

information to remove the module, if necessary.
