Analog X3 inputs/outputs

Cable specification
● Connectors: 12-pin socket/plug combination
● Cable: shielded
Wiring analog inputs/outputs
NOTICE
Shield support
If the analog inputs/outputs are wired, a shielded lead must be used. The shield must be
supported.
Procedure:
1. Strip cable for analog signals.
2. Secure the stripped connection piece of the cable with the shield connection clamp.
