Figure 1-3 Connecting the AS-i Cable

Connections to the AS-i Cable

The CP 243-2 has two connections for AS-i cables that are jumpered internally on

the CP 243-2.

This allows the CP 243-2 to be “looped” into the AS-i cable.

Caution

The load capacity of the AS-i contacts is a maximum of 3 A. If this value is exceed

on the AS-i cable, the CP 243-2 must not be “looped into” the AS-i cable but must

be connected by a separate cable (in this case only one pair of terminals of the

CP 243-2 is used). The CP 243-2 must be connected to the grounding conductor

via the ground terminal.
