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.

Figure 3-3

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.

Figure 3-4

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.
