Ensure 'C' screws to option connector have been fully tightened before fitting 'B' screws.
The front panel screws (B) are self-tapping and can be quite hard to turn. This turning
torque must not be transferred through the option board to the control board connector.
To avoid this hold the option board with one hand, while tightening the front panel screws
with the other. DO NOT hold the control board while tightening these screws.
9. Re-fit terminal block to the HTTL Option.
10. Refit Options A and B: Press the assembly into the connector on the Control Board. Ensure
that the front panel of the TechCard overlaps the front of the Control Board. Ease the
connector at the TechCard so that the two PCB's are parallel when viewed on edge.
11. Replace the control board (with attached options) into the drive. Tighten screws (A).
12. Tighten the Option A and Option B screws; or importantly, fit the blank covers and secure
with the screws. If Options are not fitted.
