Foreword

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

Control Panel on and off.

Switch off all parts of the equipment, then uncouple the Control Panel

Warning

Before opening the housing, and whenever the Control Panel 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 Control Panel is to be

disconnected from the equipment.

Disconnect the device by unplugging the connectors on the rear side of the Control Panel.

Items of equipment that have been switched off must be secured against being switched on again.

Do not exchange any parts when under power

Warning

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

off.

Fitting work on the Control Panel can result in damage:

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

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

operation.
