Table 2.6 Optional Extension
The table above shows how to combine modules with single (whole) and double
buttons.
Module Cable Interconnection
The cable is included in every extending module delivery. Both its ends are the
same. Configuration is 1:1. Connectors cannot be shifted or inserted conversely
because they are equipped with a so-called key.
The basic unit is always on the left. Extenders are chain-connected, i.e. each is
linked with its neighbour.
The cable cannot be driven through the box interconnecting holes until the boxes
have been connected (see subsection 2.3 Mounting – Mechanical Installation).

Caution
The extending modules must be connected mutually and with the basic
unit by means of a formed piece supplied with the extending module!!!
