Installation procedure 2 (when using the option together with a digital 16-bit option
card)
The dimensions of the spacers included with analog option cards and those included with digital 16-bit option
cards differ slightly. See the following diagram when determining which spacers to use. Use of the wrong spacers
may damage the product.
(1) Install the digital 16-bit option, connecting it to D port (CN10) on the control printed circuit board.
(2) Attach the two screws (a) included with the digital 16-bit option
to mounting holes ① and ② on the
digital 16-bit option, and attach four spacers (b)
to holes ③ through ⑥.
(3) Attach one spacer (d) included with the analog option card
to the option mounting fixture (c) on the
control printed circuit board.
(4) Install the analog option card so that connector CN1 (on the back of the analog option card) connects
to A port (CN3) on the control printed circuit board.
(5) Connect the power supply harness running from the top of the analog option card to CN12 on the
control printed circuit board.
(6) Tighten the three included screws (e) to secure the analog option card in place.
(7) Referring to Figures 6.1.2 and 6.1.3 "Removing the Front Cover," reverse the removal procedure to
mount the front cover.
