AC500 devices are designed according to IEC 1131 Part 2 under overvoltage category II per
DIN VDE 0110 Part 2.
For direct connection of AC Category III overvoltages provide protection measures for over-
voltage category II according to IEC-Report 664/1980 and DIN VDE 0110 Part 1.
Equivalent standards:
● DIN VDE 0110 Part 1 ↔ IEC 664
● DIN VDE 0113 Part 1 ↔ EN 60204 Part 1
● DIN VDE 0660 Part 500 ↔ EN 60439-1 ↔ IEC 439-1
All rights reserved to change design, size, weight, etc.
Both the control system AC500 and other components in the vicinity are operated with dan-
gerous contact voltages. Touching parts, which are under such voltages, can cause grave
damage to health.
In order to avoid such risks and the occurrence of material damage, persons involved with the
assembly, starting up and servicing must possess pertinent knowledge of the following:
● Automation technology sector
● Dealing with dangerous voltages
● Using standards and regulations, in particular VDE, accident prevention regulations and
regulations concerning special ambient conditions (e.g. areas potentially endangered by
explosive materials, heavy pollution or corrosive influences).
2.3 Safety instructions
The examples and diagrams in this manual are included solely for illustrative purposes.
Because of the many variants and requirements associated with any particular installation, ABB
cannot assume responsibility or liability for actual use based on the examples and diagrams.
No patent liability is assumed by ABB with respect to use of information, circuits, equipment or
software described in this manual. No liability is assumed for the direct or indirect consequences
of the improper use, improper application or inadequate maintenance of these devices. In no
event will ABB be responsible or liable for indirect or consequential damages resulting from the
use or application of this equipment.
The product family AC500 control system is designed according to EN 61131-2
IEC 61131-2 standards. Data, different from IEC 61131, are caused by the
higher requirements of Maritime Services. Other differences are described in
the technical data description of the devices.
NOTICE!
Avoidance of electrostatic charging
PLC devices and equipment are sensitive to electrostatic discharge, which can
cause internal damage and affect normal operation. Observe the following rules
when handling the system:
–
Touch a grounded object to discharge potential static.
–
Wear an approved grounding wrist strap.
–
Do not touch connectors or pins on component boards.
–
Do not touch circuit components inside the equipment.
–
If available, use a static-safe workstation.
–
When not in use, store the equipment in appropriate static-safe packaging.
