Mounting of extension module on the
basic module
1. Move the protective cap
Remove the protective cap from the connection plug on the
right-hand side of the basic module.
Place the cap on the connection plug to the right of the exten-
sion module that is to be mounted on the extreme right-hand
side of the AK assembly.
2. Assemble the extension module and the basic
module
The basic module must not be connected to voltage.
Mounting and wiring - continued
When the two snap catches for the DIN rail mounting are in the open
position, the module can be pushed into place on the DIN rail – regard-
less of where the module is on the row.
Disassembly is thus done with the two snap catches in the open posi-
tion.
In our example four extension modules are to be fitted to the basic
module. We have chosen to fit the module with relays directly on the
basic module and then the following module. The sequence is thus:
All the subsequent settings that affect the four extension modules are
determined by this sequence.
