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.
