Condensation can occur if the device is transported from a cold environment into
the operating area. The device must be dry prior to startup. You must allow for an
acclimatization time of at least twelve hours.

1

Please observe the notes on ambient conditions in Appendix B Technical
Specifications and the installation notes in Section 3.2 of this manual when

installing and operating the device. The device is to be installed so that there is no
danger of it falling or of causing damage to itself or others.

Be sure the fan ventilation slots are open so that a sufficient amount of air can be
drawn in to cool the housing interior.

Warning

!

Take note of the permissible fitting positions without fail when installing the
systems (see Section 3.2).

If the systems are installed in a non-permissible fitting position, the approvals
pursuant to UL 1950, UL 508 and EN60950 are no longer valid!

Important Information

Power Connection

Install the cables so that no one can step on them or trip over them. When you
connect the device, adhere to the relevant instructions in Chapter 2 of this manual.

Do not connect or disconnect power supply cables and data transmission lines
during thunderstorms.

In emergency situations (for example, damaged housing, damaged operator
elements, a damaged power supply cable, ingress of liquids or foreign particles),
switch off the device. Disconnect the power plug and inform the responsible
service personnel.

The SIMATIC Box PC 840 must be switched off when you connect or disconnect
peripheral devices (keyboard, mouse, printer, etc.). You can damage the PC if you
do not adhere to these instructions.

Notes for Devices with AC Power Supply

The device is intended for service in grounded electricity supply systems
(TN systems to VDE 0100, part 300, or IEC 364-3).

Service in non-grounded or impedance-grounded supply systems (IT systems) is
not intended.

The power cord should meet the respective local safety requirements.
Check whether the device’s set supply voltage is the same as the local supply

voltage.
This device is equipped with a safety-tested power supply cable. You may connect

this device only to a grounding outlet with a grounding contact.
Make certain that the socket outlet on the device or the grounding contact for the

building wiring system is freely accessible and as near to the device as possible.
The mains switch does not separate the device from the power system. To

establish a complete power separation, you must disconnect the power plug (inlet
connector on the back of the device). This location must be accessible. A central
isolating switch must be present for cabinet mounting.

Notes for Devices with DC Power Supply

The device does not fulfil the power supply connection requirements for a fire
enclosure to EN60950; therefore the mounting must meet the requirements of fire
protection enclosures in this area.

Warnung

!

Only connect the device to 24V DC power supply systems which meet the
requirements of a safe extra-low voltage (SELV); in addition, a protective
conductor must be connected.

The cable cross section has to be adapted to the short circuit current of the 24V
DC power supply unit so that the cable does not cause damages in the event of a
short circuit. Cables with a cross section of a maximum of up to 5 mm2 can be
connected.

1.4 Transport

Transporting

Despite the fact that the SIMATIC Box PC 840 is of rugged design, its internal
components are sensitive to severe vibrations or shock. You must therefore protect
the PC from severe mechanical stress when transporting it.

Use the original packing material if you have to ship the SIMATIC Box PC 840
from one location to another.

Caution

!

Risk of damage!
When transporting the PC in cold weather, when it may be submitted to extreme

variations in temperature, make sure that there is no moisture (condensation) on
or in the PC.

Important Information

The PC must be allowed to reach room temperature slowly before you switch it on.
If condensation has formed, you should wait approximately 12 hours before
switching on the PC.

disk drive.

Larger volumes of data can be stored on LS 240 data carriers than on a 1.44 MBy­tes floppy disk drive. The LS 240 has the following features:

– it is compatible with a 1.44 MB floppy disk drive, i.e. 1.44 MB or 120 MBytes

disks can also be processed.
– an LS 240 data carrier has a maximum data volume of 240 Mbytes.

When using the P tools supplied with STEP 5 (editing PCP/M files) take note that
these are no longer completely supported by the Windows Me, Windows 2000
Professional and Windows XP Professional operating systems as well as the
LS240 disk drives. P tools should be used under MS-DOS, Windows 3.x or
Windows 95 and require a standard 1.44 MB disk drive.

PGs start the taskbar under Start > Simatic > AuthorsW.

Usage Notes for LS240 Superdisks

Floppy disks up to 1.44 Mbytes as well as Superdisks up to 240 Mbytes can be
used in LS240 drives.

Track density for Superdisks is10 mm compared with the 120 mm of conventional
disks.

The LS240 drive recognizes when a Superdisk is in the drive and switches to the
higher capacity.

Due to their higher storage capacity, Superdisks are more sensitive to dirt,
temperature and shock than conventional diskettes.

Notice

In order to achieve a reliable operation and high data security, please note the
following during use:

 Store and transport the Superdisk in the protective cassette included. This will

keep dust and dirt from the disk.

 Remove Superdisk from the drive when it is not being read or written to keep

dirt particles away from the disk. Do not expose the disk to unnecessarily high
operating temperatures.

Notice

If possible avoid vibration of the device, when using Superdisks. Superdisks are
more sensitive to vibration as a result of their high track density.

Emergency Removal:

When the device is switched off, the disk can be forced out by using a pin (for
example, an opened up paper clip).

2.4.3 Hard Disk Drive

The hard disk drive is used for the storage of large quantities of data. it is fitted in a
mounting which is easily exchangeable and damped against vibration.

2-8

Caution

!

Drives are sensitive to vibrations and shock. Any vibrations occurring during
operation can lead to loss of data or damage to the drive.

If you intend transporting the unit, switch it off, and wait until the drive has come to
rest (about 20 seconds) before you move it.
