Caution
Failure to exercise proper electrostatic discharge precautions (such as
wearing a grounded wrist strap) when accessing the back of the unit or
when handling CPU or I/O modules may reset the processor or damage
electronic components, resulting in interrupted operations.
3.1 CPU Module (P152)
The CPU module contains the host processor and associated
peripherals, which form the heart of the S600+ system. Various plug-in
connections are provided on the rear backplate of the CPU module.
Refer to
Figure 3-1 for an illustration of the CPU module backplate
and to Figure 3-2 for a schematic of the CPU power terminations.
Figure 3-3 shows the wiring terminations. Additionally, the module
uses connectors and jumpers, which are set at the factory prior to
shipping. See
Section 3.5, Jumpers for further information.
It is recommended that all wiring be made with stranded wire that is no
larger than 1.5 mm
2
(0.0023 in
2
) For the communication ports, wiring
of 1.75 mm
2
to 1.65 mm
2
(0.0027 in
2
to 0.0025 in
2
) is recommended.
Power wiring is recommended to be 1.5 mm
2
(0.0023 in
2
). Observe all
local wiring practices and regulations.
Caution
Do not use a Mega or similar instrument to check for isolation or
continuity between signals on any of the S600+ connectors. These
instruments produce voltages far in excess of design parameters and
may damage the S600+ or its connectors.
