Install the Adapter 11
Mount or Replace
the Adapter to an
Existing System
Follow these steps to mount or replace an adapter.
1. Remove the existing adapter (if there is one) from the DIN rail as
follows:
a. Pull up on the RTB removal handle to remove the terminal block.
b. Disconnect the Ethernet connector from the adapter.
c. Remove the adjacent module from its base.
d. Use a small-bladed screwdriver to rotate the DIN-RAIL locking
screw to a vertical position.
This releases the locking mechanism.
e. Lift straight up to remove.
2. For the replacement adapter, slide the safety end cap up to remove.
This exposes the backplane and power connections.
3. Position the replacement adapter vertically above the DIN rail.
4. Make certain the DIN rail lock is in the horizontal position.
5. Slide the adapter down, allowing the interlocking side pieces to engage
the adjacent module.
6. Press firmly to seat the adapter on the DIN rail.
The adapter locking mechanism snaps into place.
7. Replace the adjacent module in its base.
8. Reconnect the Ethernet cable to the adapter.
9. Set the network address thumbwheel switches to the value used on the
replaced module. For more information, see Set the Network Address
on page19.
10. Insert the end of the terminal block (RTB) opposite the handle into the
base unit.
This end has a curved section that engages with the wiring base.
11. Rotate the terminal block into the wiring base until it locks itself into
place.
