2 Safety instructions
Relevant standards and regulations, accident prevention regulations and regulations on spe-
cial environmental conditions must be observed (e.g., hazardous areas due to explosive sub-
stances, heavy soiling or corrosive influences).
The devices must be handled and operated within the specified technical data and system data.
The devices contain no serviceable parts and must not be opened.
Removable covers must be closed during operation unless otherwise specified.
Any liability for the consequences of incorrect use or unauthorized repairs is rejected.
Both the AC500 control system and other components in the vicinity are operated with dan-
gerous touch voltages. Touching live components can lead to serious health implications or
even death.
To avoid such risks and the occurrence of property damage, persons involved in the installation,
commissioning and maintenance must have relevant knowledge about:
● Automation technology
● Handling of hazardous voltages
● Application of relevant standards and regulations, accident prevention regulations and reg-
ulations on special environmental conditions (e.g., hazardous areas due to explosive sub-
stances, heavy soiling or corrosive influences).
must be read and understood before using the safety configu-
ration and programming tools of Automation Builder/PS501 Control Builder Plus. Only qualified
personnel are permitted to work with AC500-S safety PLCs.
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.
The PLC was developed according to the relevant standards. Any module-specific measures
are described in the individual descriptions of the modules.
The product family AC500 control system is designed according to the EN
61131-2 and IEC 61131-2 standards. Any data that differs from IEC 61131-2,
is due to 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.
