6.2.1 SIOX - Terminal assignment of digital inputs 24 V AC/DC / 230 V AC
The 12 digital inputs (24 V AC / 230 V AC) are designed for installation monitoring and as meter inputs.
Warning - hazardous electrical voltage!
Danger of electric shock! Jumpers must always be configured while disconnected from power
and with connectors removed from inputs (terminals A1, A2 / .. / L1, L2), because these terminals
may carry 230 V AC power! The SIOX Extension Module will be destroyed if 230 V AC power is ap
plied to an input configured for 24 V AC!
Wiring of digital inputs:
230 V AC: The N conductors must be connected on one terminal level (A2 .. L2)!
24 V AC/DC: If 230 V AC and 24 V AC/DC inputs are required on a SIOX module
they must be seperated by one input which must be connected to PE!
For further details see chapter 5.5.2!
Note: In the following example the first 3 digital inputs (inputs A / B / C - 230 V AC) of the SIOX extension mo
dule are used for installation monitoring and the last input (L - 24 V AC) is used for an electricity meter.
