Take all of the modules out of the Rack, being careful not
to touch the connectors on the back.
Step 4. Loosen the bolts that hold the rack to panel approximately
1/8"-1/4". Lift the Rack slightly while holding it against the
panel until both top bolts are positioned in the larger bolt
holes and the lower two bolts have cleared the smaller
holes. Pull the Rack away from the panel and set aside.
Step 5. Position the replacement Rack against the panel at a slight
angle so that the bottom is a few inches away from the
panel. Place the Rack against the panel so that the upper
two bolts are visible through the larger part of the bolt
holes at the top of the Rack.
Carefully slide the Rack down so that the bolts are
wedged in the top (smaller) area of the bolt holes, while at
the same time moving the lower portion of the Rack
toward the cabinet or panel onto the lower bolts. The
lower bolts should be firmly wedged against the upper
edge of the lower bolt holes on the Rack. Tighten all the
bolts.
Step 6. Insert the Power Supply module into the leftmost and
widest slot in the Rack. Use a screwdriver to attach the
module to the Rack.
Step 7. If you are using the Battery BackĆUp unit, plug one end of
the Battery BackĆUp cable into the Power Supply module
faceplate connector labeled BATTERY BACK UP". Plug
the other end into the Battery BackĆUp unit. Rotate the
keyswitch on the front panel from Memory Protect to the
Program postion.
Step 8. Insert the Processor module(s) and other modules. Use a
screwdriver to attach the modules to the Rack.
Step 9. Use a screwdriver to attach the connectors to their mating
halves on the appropriate modules.
Step 10. Connect 115 VAC power to the Rack following the
instructions below.
CAUTION: Do not connect incoming AC power directly to the power supply module
faceplate.Connectpowertothecorrectterminalsontherackonly.Failuretoobservethis
precaution could result in damage to or destruction of the equipment.
a) Make certain that there is an unbroken path from the
cabinet to the plant ground.
b) Connect incoming AC power to the Rack as follows:
Rack Terminal Label Input
189 120 VAC
188 120 VAC + (hot)
Cover the incoming wire ends with a Fastont
connector and attach them securely to the appropriate
terminals using a screwdriver.
c) Connect the power and ground wires from the Rack to
the Power Supply module as follows:
