Industrial environment
The products have been designed for use in an industrial environment in compliance with the 2014/30/EU directive.
Planning and installation of the electrical system must comply with the applicable regulations and standards. Measures must prevent hazards that may result from malfunctions.
Declarations of conformity and certificates prove the suitability of the products for the intended application.
The PLC Automation catalog contains an ⮫ overview of the available declarations of conformity and certificates.
Distributer contacts
According to EU regulations, ABB AG is the manufacturer or the importer of all PLC devices.
The rating plate on each PLC device shows the manufacturing location and, if required, the contact details of the importer.

Qualified personnel
Both the AC500 control system and other components in the vicinity operate with hazardous voltages. Contact with live parts can cause serious injuries or even death.
To prevent personal injury and property damage, persons involved in installation, commissioning and maintenance must have relevant knowledge in the following areas:
-
Automation technology
-
Handling of hazardous voltages
-
Application of relevant standards and regulations (e.g., EN 60204-1), accident prevention regulations and regulations for special environmental conditions (e.g., hazardous areas due to explosive substances, heavy soiling or corrosive influences).
Applications in UL hazardous locations
Suitable for use in Class 1, Division 2, Groups A, B, C and D-T4 hazardous locations, or non-hazardous locations only.
Substitution of any component may impair suitability for Class 1, Division 2.
WARNING
Explosion hazard
Exposure to some chemicals may degrade the sealing properties of material used in the relays.
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 disconnected and that the area has been thoroughly checked to ensure that flammable materials or ignitable concentrations are not present.
The devices must not be opened when in operation. The same applies to the network interfaces.
