Wiring Instructions
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 instructions must 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!
Wiring and mounting must be performed with the voltage supply disconnected
!
IMPORTANT:
The S-DIAS module CANNOT be connected/disconnected while voltage is applied!
