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.
