In redundant configuration, two PM891 units are mounted on two separate
DIN-rails. If sufficient space is available, the units can be mounted on the same
DIN-rail.
Use the following procedure to install the processor units along the DIN-rail:
1. Mount the processor units.
2. Mount the communication interfaces on the CEX-Bus to the left of the
processor unit. If BC810 are used, the configuration of the segments should be
considered. If BC810 are not used, the interfaces can be divided between the
two CPUs in any preferred way.
3. Press the units gently together and ensure that the CEX-Bus is correctly
connected, through the connector on the unit.
4. If BC810 are used, connect the TK851 cable to the two BC810. If BC810 are
not used, mount the CEX-Bus extension cable TK850 to the units at farthest
away from the processor units or, if no units are mounted, directly to the CEXBus on the processor unit. The CEX-Bus extension cable must be connected to
both CPUs whether or not there are any other CEX-Bus units (Figure 29 on
page 99).
5. Connect the RCU Data Link Cable (TK855) and the RCU Control Link Cable
(TK856) to both CPUs.
