3.2 Mounting (or Replacing) the module on an existing system
1 Remove the Modbus plug-in connector from the front of the adapter.
2 Disconnect any wiring jumpered to the adjacent terminal base.
3 Using a screwdriver or similar tool, open the lock and remove the module
from the base unit to which the adapter will be attached.
4 Push the flexbus connector toward the right side of the terminal base to
unplug the backplane connection.
5 Release the locking tab and remove the adapter.
6 Before installing the new adapter, notice the notch on the right rear of the
adapter. This notch accepts the hook on the terminal base unit. The notch is
open at the bottom. The hook and adjacent connection point keep the
terminal base and adapter tight together, reducing the possibility of a break in
communication over the backplane.
7 Complete the adapter mounting as shown below.
Attention: Make certain that the hook on the terminal base is properly hooked into the adapter.
Failure to lock the hook into the adjacent base/adapter can result in loss of communication on the
backplane.
8 If the adapter module does not lock in place, use a screwdriver or similar
device to move the locking tab C down while pressing the adapter module
flush onto the DIN-rail. Then release the locking tab to lock the adapter
module in place. If necessary, push up on the locking tab to lock.
9 Reinstall the module into the terminal base unit.
