Wiring analog inputs/outputs
Procedure:
1. Strip cable for analog signals.
2. Secure the stripped connection piece of the cable with the shield connection clamp.
NOTICE
Shielded signal cables for analog signals
To ensure safe, fault-free operation of the system, shielded cables with shield connection
should be used for the wiring of the analog outputs.
