Page 195: Due to the batteries being connected in parallel, it is necessary,
when using the SB821 external battery, to remove the internal battery
from the processor unit in order to avoid reducing available memory
back-up time.
-200 and Page 201: Reuse of CPU modules replaced from redundant con-
figurations within the same control network, might cause control network
problems due to the MAC and IP address handling. See MAC and IP
Address Handling in Redundant Configuration on page 49. Such reuse
should not be fulfilled unless both the replaced module and the module
previously acting together with it in redundant configuration are known to
be restored from the previous mutual address swap. It is recommended to
set up an IP-config session and use the “Restore factory settings” option
subsequently followed by reassignment of the IP address or assignment
of a new IP address.
Page 200: Do not, under any circumstances, remove the RCU Link Cable
from the primary CPU now running in a single state. Removing the cable
might cause the CPU to stop.
Page 201: The unit baseplates are easily disconnected from each other by
gently prying them apart with a blade screwdriver (see Figure 23 on page
74).
Page 202: Do not replace the RCU link cable online in a previous version
than 5.0. The support for online replacement also depends on hardware
Product Revision levels. Please consult Release Notes (3BSE021377*)
for detailed information.
Page 428: If you use other power supplies, except SD82X and SD83X, to
provide the 24V d.c. for AC 800M it is required that they also are CE
marked, Underwriters Laboratories (UL ) listed and fulfill the LVD (SEL-
VandPELV) criteria.
Page 428: The AC 800M modules are IP20 semi-protected equipment and
must be mounted in non-public localities.
