DIAGRAM OF ELECTRICAL CONNECTIONS TO PERIPHERALS
To connect the accessories and peripherals to the pump remove the front cover "1", using a flat-tip screwdriver on
the two plastic screws, to access the terminal board (see Figure 9).
The "3" terminal board features spring terminals (there are no screws) for quick connection of the cables: press with
a small screwdriver at the "carved" square pin and insert the conductor previously stripped in the corresponding terminal.

The connector for the pH, RX, or Cl probe is placed in the lower part of the metering pump.
