Size 1:
Size 2:
The above drawings indicates the different installation locations for optional modules. Option slot 1 is used
for the mounting of an internal customer interface (e.g. bus module). Option location 2 for installing an
internal brake resistor is only present in size 2. The brake resistor may only be installed at the factory
and must therefore be taken into account in the order. External bus modules, 24 V power supplies can
be implemented at option locations 3L or 3R. Option locations 4 and 5 are used for the installation of M12
sockets or plug connectors or for cable glands. Only one option per option location is possible.
