Electrical connection

For the electrical installation it is recommended to use multiple conductor cables, and not
single cables, in order to guarantee the cable gland will stay watertight. The connector has a
PG7 cable gland for cables with outer diameters between 4 mm and 6 mm. The numbering
of the terminals is the following:
Terminal 2 is the normally open contact when the float is below the limit switch.
In the female connector:
Terminal 1: Common
Terminal 2: NO (Normally open)
Terminal 3: NC (Normally closed)
Earth terminal: Not connected
