The illustrations below depict potential connection layouts for the fluid-level controller module. The onboard relay can handle loads of up to 5A at 240V (AC) or 5A at 30V (DC). To connect high-power loads greater than these specification, use a contactor or a high-current-rated relay.

If this module is mounted outside, please ensure that it is placed in a waterproof and dust-proof enclosure. Moisture and dust from the outside can harm electronic components and the printed circuit board (PCB). It is also recommended to apply a protective paint or conformal coating to the PCB to shield the board and its components from the environment and prevent corrosion.
