of the case. The basin of the case can be screwed on through the two holes to the wall using
the fastening screws provided (
with the cable bushings downwards ). For easier handling
the mains module can be token out of the case.
Electrical connection

accordance with the relevant local guidelines. The sensor lines may not be fed through the
same cable channel as the supply voltage.
Notice: The system must be grounded to protect it from damage by lightening according to
regulations; sensor failure caused by electrical storms or electrostatic charging can usually
be traced to insufficient grounding.
All sensors and pumps resp. valves must be connected to the controller according to the
numbering of the chosen diagram. All sensor grounds are interconnected and fully inter-
changeable.
