Found the A06B-6047-H002 / 3 in the Fanuc 6 book. I suspect your top card is A20B-0009-0320 Ver*.
This is an M series DC drive. H002 for OM & 5M motors, H003 for 10M & 20M motors.
From the book:
If connection at CN2, 4 & 5, then S20 open
If no connection at CN2, 4 & 5, then S20 closed
Also, if a regenerative discharge unit, (External braking resistor), then S26 open
if no regenerative discharge unit, then S26 closed
Jumpers are just above the alarm LED block on the right of the card
S23 at top, S26 at bottom
S23 TCLS (enable/disable alarm for testing purposes, default open)
S22 DCAL (enable/disable alarm for testing purposes, default open)
S21 BRK (enable/disable alarm for testing purposes, default open)
S20 TOH (overheat sensor of servo transformer and / or external regen unit)
S26 Regen type (open-external, closed-internal)
As you say, you now have the book so this should match it.
