5. Reattach the power connections. See
5
in Figure 2–12. On the H7214
and H7242 regulators in positions 2 and 3, torque the screws to 27
(+/-5) inch-pounds. Replace the plastic covers that shield the power
connections on the regulators.
CAUTION:
Use the 5/16 inch screws to attach the power connections.
If you use the longer 7/16 inch screws, the power regulators may short
out.
6. Attach the two remote sense wires (17-01525-01) going to the H7214
and H7242 regulators (positions 2 and 3) at J4. The wire from the
+3.3V bus bar connects to the H7242; the wire from the +5V bus bar
connects to the H7214. See
6
. Figure 2–13 shows the bus bar voltages.
7. Attach the power distribution cable (17-01566-01) going to the H7215
regulator (position 1) at J3. At the top of J3, there is a cable retainer.
Loosen the nut that holds the cable retainer to move it up out of the
way, and then turn it to hold the power distribution cable. Tighten the
nut. See
