3.3 Installing an AS-i Module
The installation of an AS-i module on the AS-i cable is particularly simple using the
connection technique described. This is made clear by the following illustration:
Figure 3-2
1. The coupling module is screwed or clipped
onto a 35 mm standard rail. The coupling
module includes four stoppers. These are
used to close unused cable openings.

2. The AS-i cable is inserted. It locks into a
guide above the contact blades and is
secured mechanically. No electrical contact
is established. Two stoppers are inserted in
the unused cable opening.

3. By screwing down the application module,
the AS-i cable is pressed onto the contact
blades. They penetrate the conductors at
two points and guarantee a reliable
connection. After correct installation, the
module has the type of protection IP67.
