1.3 Basic safety measures

Before the Industrial PC is switched off, software that is running must be properly closed.
Otherwise it is possible that data on the storage medium is lost. Please read the section Switching the

Industrial PC on and off.

Switch off all parts of the equipment, then uncouple the fieldbus

Attention

Before opening the housing, and whenever the Industrial PC is not being used for
control purposes (such as during functional checks after a repair), all parts of the
equipment must first be switched off, after which the Industrial PC is to be
disconnected from the equipment.

Pulling out the fieldbus connection plug uncouples the PC (optional).
Items of equipment that have been switched off must be secured against being switched on again.

The Industrial PC’s power supply unit must be supplied with 24 VDC.

Do not exchange any parts when under power

Attention

When components are being fitted or removed, the supply voltage must be switched
off.

Fitting work on the Industrial PC can result in damage:

• if metal objects such as screws or tools fall onto operating circuit boards.

• if connecting cables internal to the PC are removed or inserted during

operation.

• if plug-in cards are removed or inserted when the PC is switched on.
