CARDFRAME INSTALLATION
A KT0072 Cardframe upgrade kit can be fitted to a 15U F3200 to allow it to take more than
three 8 way modules.
1.
If the system does not require large batteries
(refer to Section 4.3.4) it may be
fitted as follows, using a pop rivet gun and M4 nut driver. With FIP power not
connected, batteries not fitted.
1.
Remove the gear plate.
2.
Remove all 8 way modules.
3.
Remove the 3 sets of PCB standoffs on the left side rear of the plate.
3.
Remove the M4 nuts, washers and PCB spacers from the 3 M4 studs on the
left side of the plate.
4.
Fit the Cardframe over the studs with the M3 bushes on the right hand side.
5.
Refit the 3 PCB spacers, washers and nuts on the inside (do not yet fully
tighten).
6.
From the plate rear, with the Cardframe firmly against it, insert the 3 pop
rivets provided into the holes in the Cardframe, and rivet.
7.
Tighten the M4 nuts on the studs.
8.
Refit the gear plate to the cabinet
2.
If a system requires the Cardframe to be removable to allow the
fitting/removing of larger batteries,
then the procedure is similar to that described
in 1a above, but, instead of pop rivets, M4 screws should be used as follows:
1.
Use three M4 x 10 or M4 x 12 screws, with nuts, and shakeproof washers.
2.
Fit the screws with the heads to the rear of the gear plate, washers and nuts
inside the Cardframe.
3.
Put some Locktite (or equivalent power glue) under the heads of the screws
(but
not
on the threads).
4.
Tighten the nuts on the screws initially holding the heads of screws.
5.
Subsequent removal of the nuts (after the Locktite has dried) should be
possible without removing the gear plate.
