Removal/Insertion under power
The devices are not designed for removal or insertion under power. Because of unforeseeable consequences, it is not allowed to plug or unplug devices with the power being ON.
Make sure that all voltage sources (supply and process voltage) are switched off before doing the following:
-
Connect or disconnect any signal or terminal block.
-
Remove, mount or replace a module.
Disconnecting any powered devices while energized in a hazardous location could result in an electric arc, which could create a flammable ignition resulting in fire or explosion.
Make sure that power is removed and that the area has been thoroughly checked to ensure that flammable materials are not present prior to proceeding.
The devices must not be opened when in operation. The same applies to the network interfaces.
All modules of the AC500 range are maintenance free. Spare parts are not available and repair is not allowed. If a module is not functional any more, you have to replace the whole module.
If an I/O module is installed on a hot swap terminal unit, it is possible to replace it with the same type during runtime.
If an I/O module is installed on a terminal unit that does not support hot swap and for all other AC500 modules, proceed as follows.
-
Disconnect the power supply.
-
For processor modules, insert the memory card into the new module.
-
For communciation modules, adjust the position of the rotary switches on the new module.
-
For terminal units and terminal bases, disconnect the connectors from the old module.
-
Demount the module to be replaced as described in the ⮫ installation instructions.
-
Mount the new module as described in the installation instructions.
-
For terminal units and terminal bases, connect the connectors.
-
Reconnect the power supply.
System boots up again.
-
If necessary, update module firmware⮫ “PLC firmware/application update”.
If a processor module is replaced, you must install the firmware, the application, the licenses, passwords and the certificates on the new processor module.
If a problem persists, contact ABB technical support.
