WARNING!
Risk of electrocution!
Safe electrical isolation must be ensured for the external power supply that
generates the supply voltage. Failure to do so could result in electric shock.
The power supplies must comply with EN 60950-1:2006/A11:2009, EN
61558-2-6:11/1997.
WARNING!
Risk of electrocution!
When voltage is applied, contact with live components could result in seri-
ous or even fatal injury from an electric shock.
If voltages higher than 50 VAC or 120 VDC are connected to the control
systems PNOZmulti or PNOZmulti Mini, e.g. to switch contacts on relay
modules, please note the following:
– Specific accident prevention regulations apply.
