6.
Provide connections for power supply and network:
a.
Connect the power leads to screw terminals L+ and L- of both CPUs, and
the power supervision signals from SS8xx to screw terminals SA and SB.
b.
Connect the Control Network cables to CN1 (single bus connection) or
CN1 + CN2 (redundant bus connection). The Control Network is
connected to both CPUs.
c.
Connect the Control Builder to COM4 with cable TK212 of the Primary
CPU (if required for changing an IP address etc.). Otherwise connect the
Control Builder to the Control Network.
7.
Connect the optical ModuleBus to the optical contacts on the processor units
(see
Figure 2
on page 32 and
Figure 40
on page 131). Information regarding
optical cable selection and cable length is provided in the S800 I/O
documentation.
8.
Provide battery backup by connecting the CPUs to the external SB822 battery
units. Install them according to the instructions in
Installing the SB822
Rechargeable External Battery Unit
on page 144.
Both CPUs should be powered from the same supply (single or redundant). For
redundant power supply, see
Figure 46
on page 140.
Connection to the optical ModuleBus is identical to that for the processor unit
and for the FCI in S800 I/O (
Figure 55
on page 161).
