5.2.4
Insufficient isolation of intrinsically safe and non-intrinsically safe circuits
WARNING
Insufficient isolation of intrinsically safe and non-intrinsically safe circuits
Risk of explosion in hazardous areas.
May cause death or serious injury.
• When connecting intrinsically safe and non-intrinsically safe circuits ensure that isolation
is carried out properly in accordance with local regulations for example IEC 60079-14.
• Ensure that you observe the device approvals applicable in your country.
