3.3 Connection diagram

V
1. The electrical connection must only be carried out by qualified personnel.
2. For shock-hazard protection, the instrument must only be connected to extra-low voltages which
comply with SELV or PELV definitions, because supply voltage and analog inputs are not
electrically isolated from one another !
