5 ELECTRICAL INSTALLATION
Before connecting power supply, the appliance must be placed in its final position.
Before making electrical connections, make sure not to work on live elements.
Electrical safety is ensured only when the appliance is correctly connected to an efficient
grounding system, realized according to current safety regulations. Do not use gas pipes
as grounding.
Primary circulation pump must always be piloted by the electronic board S61, ei-
ther directly (through “N.O. contact” terminals or 0-10V signal) or indirectly (using
the above mentioned signals in logic “OR” with external BMS systems). Otherwise,
the primary circulation pump must be permanently on.
Figure 5.1 Electronic board S61 → 30 and Table 5.1 Electronic board S61 → 30 provide de-
tails of input and ouput of the S61 electronic board. The auxiliary electronic card Mod10
is shown in detail in Figure 5.2 Mod10 controller → 31.
