CAUTION
For any doubts or problems regarding the use of the system, even if not described here, please contact the qualified installer or Delios sales representative.
The DLX system must not be subjected to any type of modification. Delios declines any responsibility if the rules for correct installation are not respected and
is not responsible for the system upstream or downstream of the equipment it supplies. The exclusion of protective devices is extremely dangerous and
relieves the manufacturer of any responsibility for damage to people and things.
A first aid kit must be provided. Do not underestimate burns or wounds.
The DLX system is intended for indoor installation.
Optimal operation of the DLX system is ensured at a maximum ambient temperature of 40
°
C (104
°
F).
The DLX system must be transported and stored in indoor locations with a temperature range of -30
°
C to +70
°
C (-22
°
F and 158
°
F).
The DLX system must be used in locations with no acids, gases or other corrosive substances.
The DLX system must be used and stored in locations with relative humidity ranging from 5% to 95% without condensation.
The DLX system must be transported in locations with relative humidity ranging from 5 % to 95 %.
The DLX system must be used and stored in locations with atmospheric pressure ranging from 86 kPa to 106 kPa.
The DLX system must be transported in locations with atmospheric pressure ranging from 70 kPa to 106 kPa.
The DLX system must be used at a maximum altitude above sea level of 3000 m (9750 feet).
PV panels connection
Before starting the connection operations, make sure that the external AC line main switch is disconnected and that the AC GRID and EPS circuit
breakers are disconnected.
Before starting the connection operations, make sure that the DC line switch is off.
Before starting the connection operations, make sure that the ON/OFF switch is in the "0" position. The conductors from the solar panels are
always live.
Never disconnect the DC connectors before having switching off the circuit breaker (external or internal). Any disconnection of the connectors
during operation can generate large electrical arcs.
AC grid and EPS Connections
Before starting the connection operations, make sure that the external AC line main switch is disconnected and that the AC GRID and EPS circuit
breakers are disconnected.
Before starting the connection operations, make sure that the DC line switch is off.
Before starting the connection operations, make sure that the ON/OFF switch is in the "0" position.
CAUTION - INSTALLATION
Avoid touching the inverter enclosure during the equipment operation.
The hybrid inverter enclosure could overheat during its operation and cause burns by contact.
Guards or covers can be removed only 10 minutes after disconnecting the inverter from the power supply to allow its components to cool down and
any static electricity storage devices to discharge.
As soon as it is switched off, the surface of the equipment could be hot, therefore great care must be taken. In the event of fire, CO2 foam extinguishers
must be used, and self-vacuum systems must be used to put out fires in enclosed spaces.
Should the noise level exceed legal limits, the working area must be circumscribed and all the people who have access to the area must wear ear
defenders or ear plugs. The noise level produced by the inverter in normal working conditions is: < 50 db.
qualified installers are recommended to wear clothing and PPE provided by their employer. A first aid kit must be provided. Do not underestimate burns
or wounds.
The DLX system can only be used with photovoltaic modules that do not require the earthing of one of the poles. DLX can only be used with
photovoltaic modules that meet the specific requirements of class A in accordance with the indications of the IEC 61730 standard. A high voltage
lithium-ion battery (HV) can be connected to the DLX system at the BAT input, which acts as a storage element for the excess energy produced by the
photovoltaic generator.
The DLX system can be connected to the distribution network only in the countries which the system is certified for.
The DLX inverter is equipped with an external earthing contact which must be connected to the protective conductor in addition to the earth
connection provided by the GRID terminal block for connection to the public AC grid.
An electric shock can be fatal. Avoid touching internal or external normally live parts whilst the system is powered on.
Cables and connections must always be secured, in good conditions, insulated and suitably sized.
The equipment contains capacitors that store static electricity, which could produce dangerous electric discharges. Make sure that the devices have
discharged their energy before carrying out any work on the equipment.
During the installation, make sure that the inverter is powered off.
Do not mount the DLX system above or under flammable building materials. Do not install the DLX system in areas where highly flammable substances
are present. Do not install the DLX system in areas subject to explosion hazard.
The DLX is not equipped with specific lifting tools. Do not underestimate the weight, check technical characteristics. Do not move or stop the hanging
load above people or things. Do not let it drop or lay with too much force.
To prevent the risk of electric shock or other injury, check that there are no electrical or hydraulic lines in the walls before drilling the mounting holes of
the DLX. Please note that the appropriate type of plastic plugs and screws must be selected by a qualified installer.
WARNING - OPERATING PHASE
WARNING - INSTALLATION
WARNING - MAINTENANCE and DEINSTALLATION
All controls of the DLX system should be performed exclusively through the official DLX system UI in the way instructed by the qualified installer
ensuring that the system is in the nominal operation mode. Any failure to do so will lead to the product misuse, its damage, malfunction and a
potential person injury.
The repair or replacement of parts of the system by personnel who are not qualified will immediately invalidate the product guarantee. Only
genuine or Delios approved spare parts must be used. Using no genuine spare parts or not Delios approved spare parts will immediately
invalidate the product guarantee. Immediately replace the components that do not appear in perfect conditions.
Before starting any maintenance or uninstall operations, make sure that the system has been switched off, and that the AC line external main
switch has been set to off.
Wait at least 10 minutes before removing the DLX system from the wall. The inverter enclosure could overheat during its operation and cause
burns by contact.
Do not carry out other operations on the inverter for at least 10 minutes. The inverter contains capacitors that need a minimum time to
discharge.
Never disconnect the AC or DC connectors connected to the DLX system before having disconnected the protection switches (external and
internal). Any disconnection of the connectors during operation can generate large electrical arcs.
It is absolutely forbidden to open the DLX system except as provided in this manual.
The DLX system must not be subjected to any type of modification. If the operator does not comply with what is described, the manufacturer
declines all responsibility.
Batteries produce electricity and can cause electric shock or fire in the event of a short circuit or incorrect installation.
The conductors from the solar panels are always live. The voltage from a string of solar panels can reach 1000 V!
CAUTION - PRODUCT DISPOSAL
In order to comply with European Directive 2002/96/EC on electrical and electronic waste and its implementation as a national law,
electrical equipment that has reached the end of its useful life and discharged batteries must be separated from generic waste and
delivered to authorised collection and recycling centres.
Delios is not responsible for the logistic transportation from the end-user house to the recycling center.
