Cod.: 240.010.0042
DLS / DLS-C Series
4.3 Checking the Box Contents
The DLS box must contain the following parts:
• DLS hybrid inverter.
• Top and bottom bracket for wall mounting.
• Support for wall mounting.
• Instruction manual - Operation, installation, maintenance.
• Quick connectors and related contacts for PV strings wiring and connection.
• Wi-Fi dongle for connection to a local wireless network.
4.4 Positioning the DLS
With reference to Figure 01, the installation position of the DLS must meet the following conditions:
• The DLS must be installed indoors in a room with relative humidity ranging from 5% to 95% without
condensation.
• The DLS optimal operation is ensured if the maximum ambient temperature of 40°C is not excee-
ded. Should the temperature become too high, the automatic power derating will trip to prevent the
system from overheating.
• Do not install the DLS in a position directly exposed to the sun.
• Install the DLS as close as possible to the meter panel.
• Install the DLS in such a way as to Ensure easy access to the controls and to the connections
• Install the DLS in such a way as to have the LCD display at eye height.
• Install the DLS and the power lines in such a way as to prevent access to pets (rodents in Particu-
lar).
• The DLS, in some specic conditions, can produce a slight buzzing noise during its operation. This
noise is normal and does not affect its performance but can be annoying if the unit is mounted
onto a wall of an inhabited area, onto a wall adjacent to an inhabited area or onto certain type of
materials (such as thin wooden panels or metal plates).
• The position must not be accessible to children.
• The wall must be vertical, with a maximum tilt of ±5°.
• The surface where the DLS will be installed must withstand its weight (25kg).
• The DLS must be installed leaving a 500mm clearance where the bottom of the unit is located to
Ensure easy cabling and connection. There are no restrictions for the top of the unit as the venti-
lation system does not require vertical outlets.
• In the case of multiple installation of several DLS, a side clearance of 500 mm between the units
must be provided.
• The DLS system must be used at a maximum altitude above sea level of 3000m (9750 feet). For
altitudes above 2000m, due to the rarefaction of the air, specic conditions may occur which must
be considered when choosing the place of installation. All installations at altitudes above 2000m
must be assessed case by case considering the following critical issues:
- less efcient cooling,
- decrease in the dielectric strength of the air and, in the presence of high voltages, the creation
of electric arcs,
- presence of cosmic radiation that can affect the correct functioning of the electronic components.
• Do not mount the DLS on or under ammable building materials.
• Do not install the DLS in areas where highly ammable substances are present.
• Do not install the DLS in areas subject to explosion hazard.
