Controller CPU Installation Procedure
Follow the procedure in Table 1 to install a Controller CPU module in a controller rack.
Table 1 – Controller CPU Installation
Step
1 Orient the controller rack to have the open side of the enclosure facing forward
with the power supply module located on the left and I/O module slots on the
right (See
).
2 Remove the Controller CPU module from its shipping container.
3 On the new CPU set/verify serial port switch settings.
Only one port may be a Modbus Master. It can be assigned to either port.
A small slotted screwdriver or paperclip works well; avoid using pencils because
their residue can damage the switch.
4 Insert the module into the dedicated slot location in the rack adjacent to the
power supply. Orient the module with module name at top. Align the module
printed circuit board with the card guide slots in the chassis. Press the CPU
module into the slot until the rear connector engages the mating connector of the
rack backplane. (See Figure 2)
Secure the Controller CPU module top and bottom with the captive mounting
5
screws. Torque settings 0,4 - 0,5 Nm (3.5 – 4.4 Lb-In.)
6 Do not install the battery at this time. See instructions in the Controller
Installation and User's Guide (document #51-52-25-154) for additional Controller
CPU setup information and battery installation.
