Caution

The electronic components of the printed circuit boards are extremely sensitive to
electrostatic discharge. Certain precautionary measures are therefore necessary
when handling such components. These measures are explained in the guidelines
for handling electrostatically sensitive devices (ESD) in Appendix A.

Installing the SDRAM Cards

To plug in expansion submodules, proceed as follows:

1. Open the unit as described in Section 4.1.

2. Plug the cards into the slots. Note the safety recess on the connector side of
the SDRAM card.

3. Push the card down applying light pressure until it locks into place.

4. Close the unit.

Installation

Caution

Make sure that the cards sit securely in the slots, otherwise they can fall out and
be damaged.

The memory configuration is detected automatically. When you switch on the unit,
the distribution of base and extended memory is displayed on the screen.

4.3 Replacing the Backup Battery

Battery Power Supply for Real-Time Clock and Configuration

A backup battery (3.6 V-lithium battery) powers the the real-time clock even after
the SIMATIC Box PC 840 is switched off. In addition to the time of day, all the
information about the SIMATIC Box PC 840 (device configuration) is stored in
RAM. If the backup battery fails or is removed, all these data are lost.

The clock uses very little power and the lithium battery has a high capacity so that
the battery can provide backup power for the real-time clock for many years and
seldom needs to be replaced.

Battery Voltage too Low

If the battery voltage is too low, the time is lost, and a correct device configuration
can no longer be guaranteed.

In this case, you must replace the backup battery. The battery is in a battery holder
below the device fan.

Replacing the Battery

To change the battery, proceed as follows:

1. Remove the power cable and all the connecting cables.

2. Open the unit as described in Section 4.1.

3. Change the backup battery inserted in the motherboard by pulling out the
connector and removing the battery from the battery holder.

4. Secure the new battery in its holder.

5. Insert the battery connector in the motherboard.

6. Close the unit.

Figure 4-5 Position of the Backup Battery

Caution

Risk of damage!
Only replace the lithium battery with an identical battery or with a type

recommended by the manufacturer (Order No.: W79084-E1003-B1).
Dispose of used batteries in keeping with local regulations.

Changing SETUP

If you change the battery or unplug the battery connector you must run the
BIOS-SETUP program to reset your programming device configuration data (see
Chapter 5).

Notes about the Cards

The SIMATIC Box PC 840 is designed for the use with cards as per the AT/
PCI specification. The dimensions of the cards may not exceed the stated
dimensions. If the height is exceeded, contact problems, malfunctions and
difficulties with the assembly cannot be excluded. The illustrations show cards with
a full AT/PCI overall length. Depending on the slot, there may be restrictions on the
overall length.

Note about Long PCI Cards

Before long PCI cards can be inserted into the guides of the fan trough, they must
be fitted with a so-called extender (this should form part of the scope of supply of
long PCI boards). Long PCI cards can be inserted into the guides of ISA modules
by means of this extender.
