CAUTION
1 The fan unit must be removed before the base
printedcircuit board can be dismounted. If you attempt to
dismount the base printedcircuit board without removing
the fan unit, both the fan unit and base printedcircuit board
may be damaged.
2 If there is an I/O Link cable under the unit, an attempt to
dismount the base printedcircuit board without removing
the cable may damage the plastic case.
3 When the base printedcircuit board is dismounted, the
content of the Power Mate SRAM memory may be lost while
it is kept dismounted. Before dismounting the base
printedcircuit board, be sure to save the content of the
SRAM memory to the builtin FROM. See the relevant
description in Appendix E or F.
4 When dismounting and mounting the base printedcircuit
board with the battery connected, be careful not cause it to
touch other metal portions, because the battery voltage is
being applied to the printedcircuit board.
1) Detach all cables other than the battery cables. If there is a cable in the
lower section of the unit (on the base PCB and option board), do not
forget to detach it also. (Check that a detached connector is labeled its
connector number.)
2) Dismount the fan unit by following the dismounting procedure
described in Section 2.5.2.
3) Hold the base printedcircuit board by grabbing its handles, A and B.
(See Fig. 2.6.1.)
4) Pull out the base printedcircuit board by pushing it at handle B.
NOTE
1 The battery is attached to the face plate of the base
printedcircuit board. It is pulled out together with the base
printedcircuit board.
2 The base printedcircuit board can be dismounted without
removing option boards; cables attached to the option
boards must be dismounted, however.
