Communications Module”).

Insert the new module through the module slot on the front of the
ROC827 housing. Make sure the label on the front of the module is
facing right side up. Gently slide the module in place until it contacts
properly with the connectors on the backplane.

Note

: If the module stops and will not go any further, do not force the

module. Remove the module and see if the pins are bent. If so, gently
straighten the pins and re-insert the module. The back of the module
must connect fully with the connectors on the backplane.

Gently press the module into its mating connectors on the backplane
until the connectors firmly seat.

5.

Install the retaining captive screws to secure the module.

6.

Wire the module (refer to “Wiring Communications Modules”).

Note

: All modules have removable terminal blocks for convenient

wiring and servicing. Twisted-pair cable is recommended for I/O
signal wiring. The removable terminal blocks accept 12 AWG or
smaller wire.

7.

For dial-up modem communications, connect the cable to the RJ-11
connector on the communications module.

Note

: If you are installing a modem module, it is recommended that

you install a surge protector between the RJ-11 jack and the outside
line.

8.

Replace the wire channel cover.
