Page 184: Note that a Backup CPU with severe communication errors on 

the ModuleBus will be rejected (if ModuleBus is part of the HW configuration) and synchronized state will never be reached as long as error 

remains.

Page 189: The RCU Link Cable must NEVER be removed from the primary Processor Unit during redundant operation. Removal of the cable 

may cause the unit to stop.

when using the SB821 external battery, to remove the internal battery 

from the PM8xx in order to avoid reducing available memory back-up time

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 configurations 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 (SELVandPELV) criteria.

Page 428: The AC 800M modules are IP20 semi-protected equipment and 

must be mounted in non-public localities.

About This User Manual

General

This book describes the hardware platform AC 800M. It also describes in detail how 

to install, configure, operate and perform the necessary maintenance on all 

equipment making up the AC 800M or AC 800M HI controllers.

Control Builder is used to configure and program the AC 800M controller, and is 

referred to in this manual as Control Builder. For information on the controller 

software, see controller software documentation. 

For important information about late changes and work-arounds for known 

problems, refer to the Release Notes (see Released User Manuals and Release Notes

on page 28). 

User Manual Conventions

Microsoft Windows conventions are normally used for the standard presentation of 

material when entering text, key sequences, prompts, messages, menu items, screen 

elements, etc.

Any security measures described in this User Manual, for example, for user 

access, password security, network security, firewalls, virus protection, etc., 

represent possible steps that a user of an 800xA System may want to consider 

based on a risk assessment for a particular application and installation. This risk 

assessment, as well as the proper implementation, configuration, installation, 

operation, administration, and maintenance of all relevant security related 

equipment, software, and procedures, are the responsibility of the user of the 

800xA System

Warning, Caution, Information, and Tip Icons

This publication includes Warning, Caution, and Information where appropriate 

to point out safety related or other important information. It also includes Tip to 

point out useful hints to the reader. The corresponding symbols should be 

interpreted as follows:

Although Warning hazards are related to personal injury, and Caution hazards are 

associated with equipment or property damage, it should be understood that 

operation of damaged equipment could, under certain operational conditions, result 

in degraded process performance leading to personal injury or death. Therefore, 

fully comply with all Warning and Caution notices.

Terminology

A complete and comprehensive list of terms is included in System 800xA System 

Guide Functional Description (3BSE038018*). The listing includes terms and 

definitions that apply to the 800xA System where the usage is different from 

commonly accepted industry standard definitions and definitions given in standard 

dictionaries such as Webster’s Dictionary of Computer Terms.
