Removing
WARNING
Risk of electric shock
Before starting removal work of any kind, the main switch of the system must be opened
and measures taken to prevent it from being reclosed. If this instruction is not observed,
touching live parts can result in death or serious injury.
NOTICE
Risk of damage by breaking off the plug connector
The components can only be safely and reliably removed when the plug connectors have
been released. Release the plug connectors, before removing or replacing the basic unit
and supplementary modules.
1.
Switch the basic unit into a no-voltage condition.
Note
For a hardware configuration with one or several buffer components, after bringing the
basic unit into a no-voltage condition, the first step is to discharge the energy saved in the
buffer components. This can take several minutes under no load conditions (all of the
outputs are switched off).
For buffer modules with double layer capacitors, and for the UPS module, you can exit
buffering by opening the "ON" contact.
2.
Release all of the connections at the plug-in terminals, and if necessary, the
Ethernet/PROFINET connection.
3.
Release all of the plug connectors at the basic unit and the supplementary modules being
used.
To do this, press latch
①
and withdraw the plug connector.
