PRELIMINARY CHECKS
AND LIMITS OF USE
Perform the checks described in this chapter to ensure that the
product is suited to the characteristics of the automation device to
be supplied.
Nearby the automation device to be supplied, identify the most
suitable point for installing the solar panel and the most suitable
point for installing the accumulator unit, taking the following
points into consideration.
Solar panel
• The maximum length of the solar panel cable should not
exceed 10 m.
Use a 2x1 mm
cable (maximum outer diameter 6.5 mm)
2
• The surface selected for fixing both devices should be of solid
material and should guarantee stable fixing
• The location selected for installation of the panel should
guarantee 100% direct sunlight throughout the year
• The location selected for installation of the panel should
be away from plants, walls or anything else that might cast
shadows, even partial, over the sensitive surface.
Partial shadows significantly reduce the energy capacity of the
panel.
Accumulator
• The maximum length of the cable carrying power to the
control unit should not exceed 3 m.
Use a 2x1,5 mm
cable (maximum outer diameter 10 mm)
2
• The device should be installed in a location protected from
direct sunlight and possibly also at low temperature.
Such extreme conditions compromise battery yield and
lifespan.
• Never allow the battery to discharge to the point where the
red LED remains on, since this risks irreparable damage to the
battery.
