Relevant standards and regulations, accident prevention regulations and regulations on special environmental conditions must be observed (e.g., hazardous areas due to explosive substances, 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.
Qualified personnel
Both the AC500 control system and other components in the vicinity are operated with dangerous 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 the following:
-
Automation technology
-
Handling of hazardous voltages
-
Application of relevant standards and regulations, accident prevention regulations and regulations on special environmental conditions (e.g., hazardous areas due to explosive substances, heavy soiling or corrosive influences).
Functional safety
The AC500-S safety user manual must be read and understood before using the safety configuration and programming tools of Automation Builder/PS501 Control Builder Plus. Only qualified personnel are permitted to work with AC500-S safety PLCs.
General information
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.
PLC-specific safety notices
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.
NOTICE
Use of suitable enclosure
The devices must be mounted in a control cabinet that ensures compliance with the specified environmental conditions.
Cleaning instructions
Cleaning instructions
Do not use cleaning agent for cleaning the device.
Use a damp cloth instead.
Connection plans and a user program must be created so that no dangerous situations can occur during normal operation or failure.
The application must be tested to ensure that no dangerous situations can occur during operation.
Do not operate devices outside of the specified, technical data!
Trouble-free functioning cannot be ensured outside of the specified data.
NOTICE
PLC damage due to missing grounding
-
Make sure to ground the devices.
-
The grounding (switch cabinet grounding) is supplied both by the mains connection (or 24 V supply voltage) and via the DIN rail. The DIN rail must be connected to ground before power is supplied to the device. The grounding may be removed only if it is certain that no more power is being supplied to the control system.
-
In case of screw mounting, use metal screws for grounding.
CAUTION
Do not obstruct the ventilation for cooling!
The ventilation slots on the upper and lower sides of the devices must not be covered.
CAUTION
Run signal and power wiring separately!
Signal and supply lines (power cables) must be laid out so that no malfunctions due to capacitive and inductive interference can occur (EMC).
WARNING
Warning sign on the module!
This indicates that dangerous voltages may be present or that surfaces may have dangerous temperatures.
WARNING
Splaying of strands can cause hazards!
Avoid splayed strands when wiring terminals with stranded conductors.
-
Ferrules can be used to prevent splaying.
WARNING
Removal/Insertion under power
Removal or insertion under power is permissible only if all conditions for hot swapping are fullfilled.
⮫ “Replace an I/O module with hot swap”
The devices are not designed for removal or insertion under power when the conditions for hot swap do not apply. Because of unforeseeable consequences, it is not allowed to plug in or unplug devices with the power being ON.
Make sure that all voltage sources (supply and process voltage) are switched off before doing any of the following actions:
-
Connect or disconnect any signal or terminal block.
-
Remove, mount or replace a module.
Disconnecting any powered devices while they are energized in a hazardous location could result in an electric arc, which could create an ignition source resulting in fire or explosion.
Prior to proceeding, make sure that power is been disconnected and that the area has been thoroughly checked to ensure that flammable materials are not present.
The devices must not be opened when in operation. The same applies to the network interfaces.
Information on batteries
CAUTION
Use only ABB approved lithium battery modules!
At the end of the battery’s lifetime, always replace it only with a genuine battery module.
CAUTION
Risk of explosion!
Do not open, re-charge or disassemble lithium batteries. Attempting to charge lithium batteries will lead to overheating and can cause explosions.
Protect them from heat and fire and store them in a dry place.
Never short-circuit or operate lithium batteries with the polarities reversed. The batteries are likely to overheat and explode. Avoid unintentional short circuiting do not store batteries in metal containers and do not place them on metallic surfaces. Escaping lithium is a health hazard.
