PLD-Hs with functional safety (FS) can be used only in the PL 62xx FS. A
safety-related PLD must not be inserted after a PLD without FS, or after an
empty slot. Safety-related PLDs must be inserted—one after the other—
into successive slots without interruption (empty slot). The normal PLDs or
PLAs must not be inserted until all PLDs with FS have been inserted.
