Install Your POINT I/O or ArmorPOINT I/O Adapter Chapter 2
Replace An Adapter Use these procedures to install a replacement POINT I/O adapter to an existing
system.
1. Disconnect the Ethernet connector(s) from the adapter.
2. Pull up on the Removable Terminal Block (RTB) handle to remove the
terminal block.
3. Remove the adjacent module from its mounting base.
4. Use a small bladed screwdriver to rotate the DIN rail locking screw
(orange) to a vertical position. This releases the locking mechanism.
5. Lift the adapter straight up to remove.
6. Position the replacement adapter vertically above the DIN rail, making
certain the DIN rail locking screw (orange) is in the horizontal position.
7. Slide the adapter down, allowing the interlocking side pieces to engage the
adjacent module.
8. Press firmly to seat the adapter on the DIN rail, noting that the adapter
locking mechanism will snap into place.
9. Set the network address on the network address thumbwheel.
10. Insert the end of the Removable Terminal Block opposite the handle into
the Removable Terminal Block base unit, noting that this end has a curved
section that engages with the base unit.
11. Rotate the Removable Terminal Block into the wiring base until it locks
into place.
12. Replace the adjacent module in its mounting base.
13. Reconnect the Ethernet cable(s) to the adapter.
14. Set the IP Address for this module (see
Set the Network Address in
chapter 3 ).
15. Configure the adapter’s chassis size.
ATTENTION: Do not remove or replace an Adapter Module while power
is applied. Interruption of the backplane can result in unintentional
operation or machine motion.
WARNING: When you insert or remove the module while backplane
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. Repeated electrical arcing causes excessive wear to contacts
on both the module and its mating connector. Worn contacts may create
electrical resistance that can affect module operation.
