6.2 Note
The input filters, which suppress noise signals, allow operation in harsh environmental
conditions. A careful wiring method is also recommended to ensure error-free function.
The following installation guidelines should be observed:
•
Avoid parallel connections between input lines and load-bearing circuits.
•
Protective circuits for all relays (RC networks or free-wheeling diodes)
•
Correct wiring to ground
The ground bus should be connected to the control cabinet when possible!
Si possible la terre doit être connectée à l'armoire de commande!
The wiring and assembly must be performed when no voltage is applied!
Le câblage et l'installation ne doivent être effectués que sur un système hors
tension !
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.
