CAUTION / WARNINGS
The housings for the cables for the plugs are provided
respectively for cable Ø 9.5÷10 mm and Ø 8.5÷9 mm,
this ensures the protection rating is IP 54 (Standard IEC
EN60529) for the electrical panel.
•
To reclose the electrical panel lid, fix the screws (1) with a
torque of about 5 Nm to ensure the correct seal.
To gain access to the control panel (8), slide the transparent
door (7) for a short distance following the direction on the arrow
indicated in the figure exerting slight pressure with a tool (e.g. a
screwdriver) following the arrows' direction and slide it for a short
distance to separate it from the cover.
• To secure the transparent door on the panel properly, position
the hooks at their hooking points (9), slide the door in the
direction indicated by the arrow until you hear a click that
ensures its seal.
CAUTION / WARNINGS
Only professionally qualified personnel may open the
burner electrical switchboard.
•
In case of phase-phase 230V electrical grids, if these latter are
unbalanced, the voltage between flame detection electrode and
ground can not be enough to ensure burner correct operation.
The problem is solved by using a type AR1 insulating transformer
cod.0005020028 connected as shown in the following diagram.
