8.2 Note
To ensure error-free operation, a careful wiring method must be followed:
• The 0 V connection of the supply voltage must be connected with the 0 V collection
point over the shortest route possible.
• The DIN rail must have an adequate mass connection.
• The lines connected to the source of the analog components must be as short as possi-
ble 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.
• Protective circuits for all relays (RC networks or free-wheeling diodes)
• Correct wiring to mass
