Installation / Set-up
The units must only be installed, connected and set up by qualified staff. The qualified staff
must have knowledge of protection classes, regulations and provisions for apparatus in
hazardous areas.
Check whether the classification (see table 1 above and marking on the unit) is suitable for
the application.
• Connection only to intrinsically safe circuits which are approved with the EC type test
certificate and do not exceed the following maximum values:
• Permissible operating temperature of the application (referred to the maximum power
which can be supplied):
• Maximum effective internal inductance (Li) and capacitance (Ci):
