19. GROUND CONDUCTOR CONNECTIONS
The Yellow/Green ground terminal in the electric pump cable must be connected to the grounding circuit of the system
before the other terminals are connected. Furthermore, it must be the last terminal to be disconnected if the electric pump
is disconnected.
For electric pumps in flameproof version, an additional external ground terminal located in the cable input area is required.
Connection of this terminal with the grounding circuit of the system is at the installer's charge.
