After the lower part of the front has been removed (pos. 6), the terminal
box becomes accessible for drive and output signals. The PCB (pos. 9)
may be slightly pulled out from the pump housing together with the
connection terminals (pos. 2, 3, 7 & 8). The terminals can be detached.
For the connection of a suction lance, the plug (pos. 4) is provided at the front. If no suction lance is used, the
supplied cover cap (pos. 5) with the integrated bridges must be attached. With the selector switch (pos. 10)
the contact of the fault or empty signal relay can be switched from normally open function to normally closed
function.
