4.2 Note
The signals recorded by the analog modules are very small, as compared to the digital sig-
nals. To ensure error-free operation, a careful wiring method must be followed:
•
The DIN rail must have an adequate connection to mass.
•
The lines connected to the source of the analog signals must be as short as possible and
parallel wiring to digital signal lines must be avoided.
•
The signal lines must be shielded.
•
The shielding must be connected to a shielding bus.
•
Avoid parallel connections between input lines and load-bearing circuits.
•
Protective circuits for all relays (RC networks or free-wheeling diodes).
The ground bus should be connected to the control cabinet when possible!
Si possible la terre doit être connectée à l'armoire de commande!
IMPORTANT:
The S-DIAS module CANNOT be connected or disconnected while voltage is applied!
IMPORTANT:
Le module S-Dias NE PEUT PAS être inséré ou retiré sous tension.
