Redundant H41X Base Rack (24 VDC)
The I/O processing module in the H41X base rack and that in the extension rack must be
powered from different power supply units to implement redundant I/O levels in the
HIQuad H41X system. To this end, e.g., the I/O processing module in the H41X base rack can
be connected to L1+ (terminal XG5.13) and the I/O processing module in the extension rack
(terminals XG.3, L+), see Figure 20. The power supply units must be able to bridge voltage
dropouts of up to 20 ms.
