Basic safety measures
Only switch the PC off after
closing the software
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.
Attention
Switch off all parts of the equipment, then uncouple the fieldbus
Before opening the housing of the PC, and whenever the PC is being
used for purposes other than plant control, such as during functional tests
following repair, all parts of the equipment must first be switched off, after
which the Industrial PC can be uncoupled from the plant.
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 24VDC.
CAUTION
Do not open the power supply unit while voltage is applied!
The supply voltage must be switched off before the power supply unit
housing is opened.
Attention
Do not exchange any parts when under power
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.
DANGER
High Voltage!
Displays used for the Control Panel’s LC-display are operated with a
voltage of up to 1000 V, depending on type. For that reason:
The supply voltage must be disconnected before the housing of the
Control Panel is opened.
