Multiple flooding zones modules are mounted on a DIN rail:
- XCA1031 : in the 19" cabinet where XC1003-A control units are installed
- XCA1030 : in each XC1003-A (see Fig. 3)
The drawing below shows a connection example between XCA1030 modules and
the XCA1031 for a 3 flooding zones installation.
Note: to ensure power supply redundancy, connect the 24V power supply to the
XCA1031 module from two XC10 panels. Otherwise, a fault message is displayed
on all XC10 panels.
