Installing CPU cards

The CPU card's components include CMOS chips which are sensitive to static electricity.
Before touching the CPU card touch a grounded metal object, such as any unpainted
surface on the matrix, to dissipate static electricity. While handling the CPU card, be careful
not to bend any of the card's connector pins or component leads.
Before operating the CPU card the card's battery must be reconnected.
Note: The CPU card is shipped with a disconnected battery to preserve battery life. For
instructions on reconnecting the battery, see 4.1.3 Reconnecting the CPU card backup
battery.
The CPU card switch settings for normal operation (watchdog enabled) are shown in Figure
5.
Note: Store spare CPU cards in unused slots in the matrix or in electrically insulated packaging
such as anti-static heavy duty plastic bags.
To insert a CPU card in the matrix:
1) Carefully place the card in the appropriate slot. Make sure the card is aligned with
the top and bottom precision guides.
