1.4 Electrical connection of the LMV37.4...

The LMV37.4... operates with the following low-voltages:
•
SELV (Safety Extra Low-Voltage) and PELV (Protective Extra Low-Voltage) ensure
protection against electric shock hazard
•
FELV (Functional Extra Low Voltage) without safe separation offers no protection
which, in the event of fault, would not exclude risks
Figure 1: Electrical connection
Note
SELV or PELV depends on the safety class of the connected components. In the case
of PELV, the relevant component is connected to protective earth.
