the module to the Rack. Store the keyswitch keys in a
secure area.
c) Connect the Battery BackĆUp unit, if used. Plug one
end of the Battery BackĆUp cable into the Power
Supply module faceplate connector labeled BATTERY
BACK UP". Plug the other end of the cable into the
Battery BackĆUp unit. Rotate the keyswitch on the front
panel from Memory Protect to the Program position.
Step 3.
Mount the terminal strip end of the terminal strip/connector
assemblies for I/O modules on the panel or on lashing
bars. The terminal strips should be mounted to permit
easy access to the screw terminals. Make certain that the
strips are close enough to the Rack so that the connecting
cables will reach between terminal strips and the modules.
Most cables are approximately 60" long.
Step 4.
Fasten wiring for the external hardware to the terminal
strips. Make certain that all field wires are securely
attached. Label all terminal strips and field wires to allow
easy reconnection at a later date.
For I/O modules, note carefully that bit numbers and wire
numbers (located on wires between the faceplate
connector and terminal strip) are not the same. Refer to
the installation section of the instruction manuals
describing the I/O modules for more information.
Step 5.
Take the Processor module(s) and other modules out of
their shipping containers and insert them into the desired
slots. See figure 2.6 for slot restrictions for certain
modules. Use a screwdriver to attach the modules to the
Rack.
Step 6.
Attach the connector ends of the terminal strip/connector
assemblies to their mating halves on the appropriate
modules. Use a screwdriver to attach the connectors to
the modules. Use the cable guides at the base of the rack
to keep cables separate.
Note that in most cases both the connectors and their
mating halves are equipped with movable keys". These
keys should be used to prevent the wrong connector from
being plugged into a module in the event that the
connector needs to be removed and then reĆattached
later.
At the time of installation, rotate the keys on the connector
and the mating half on the module to mirror image
positions so that they can be connected together securely.
For all modules equipped with keys, the key on each
successive module in the Rack should be rotated one
position to the right of the key on the preceding module.
Step 7.
Wire the Rack following the instructions below.
CAUTION: Do not connect incoming AC power directly to the power supply module
faceplate. Connect AC power to the correct terminals on the rack only. Failure to observe
this precaution could result in damage to or destruction of the equipment.
