The installation must only be carried out only by qualified personnel. They must always use the personal protective equipment required by the
laws of the country of destination and anything else provided to their employer.
The DLX system can also operate without the connection to the grid (off-grid). Under these conditions and based on the system settings, the
hybrid inverter output can be automatically switched to the EPS port which, by means of an external interlock system, will feed the loads
connected to a privileged line. According to the safety provisions in force in the country of installation, the NEUTRAL line may have to be
connected to the earth potential to guarantee the operation of the protection systems against direct discharge provided for the privileged line
and located downstream of the hybrid inverter and / or to ensure the correct operation of the loads connected to the EPS port. If, due to
particular needs, this connection should not be made, the hybrid inverter output remains floating.
Emergency power to the EPS port is automatically turned on and off based on PV panels irradiation conditions and battery charge status. This
means that during an emergency the power supply of the EPS port can be unexpectedly restored even in standby mode. For this reason, in order
to avoid possible injuries from electric shock, before carrying out any installation or maintenance work on the home network, it is necessary to
deactivate the DLX operation using the ON/OFF switch and disconnect it both from the AC power supply, by opening the main circuit breaker,
and from the photovoltaic field, by opening the DC disconnector integrated in the DLX.
PV panels, when exposed to the sun, can produce dangerous voltages. It is recommended to carry out all the procedures necessary to make the
work area safe.
The DLX system operates with high voltage lithium-ion batteries (HV). Batteries produce electricity and can cause electric shock or fire in the
event of a short circuit or incorrect installation. Only high voltage (HV) lithium-ion batteries approved by Delios can be connected to the DLX
system. The use of non-approved batteries can affect the correct functioning of the system and relieves Delios from all liabilities and invalidates
the guarantee. Batteries must be installed in a suitable area that complies with local regulations. The installation area must ensure enough
ventilation and the absence of open flames and sparks as potentially explosive gases may be generated during operation.
These safety guidelines apply to the following DLX systems and product life use phases:

Safety Guidelines
Save these instructions.
These safety guidelines contain essential information that must be followed during the installation of the DLX system according to the procedure outlined in the DLX installation manual. Instructions must be carefully read and understood before
operating the equipment and be saved for future reference. The DLX system is a product for residential application only and installation must be done in a dry, indoor environment. Optimal operation of the DLX system is ensured at a maximum ambient temperature of
40
°
C, free of conductive contaminant.
NOTE : The DLX system can only be installed by qualified personnel w h o needs to fully understand and apply provided safety instructions in order to avoid electrical hazard shock, potential death and sever product
damage.
CAUTION
SYMBOLS ADOPTED
Safety related icons
Imminent dangers causing serious injuries. Danger of death.
Hazardous behaviors that could cause serious injuries.
Hazardous behaviors that could cause death.
Behaviors that could cause minor injuries to people or minor damages to things.
Hazard icons
An electric shock can be fatal.
Avoid touching internal or external normally live parts whilst the system is powered on.
Surfaces can be hot.
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.
The 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.
Electromagnetic fields may have harmful effects (unknown to date) on the health of people who are subjected to long exposure. Avoid
standing for long periods of time at less than 20 cm from the inverter.
Mandatory action symbols
Read the instructions. These instructions are intended for qualified installers.
The qualified installer must be an expert in the field and must therefore be responsible for commissioning the system according to the
manufacturer's instructions and local legislation.
Any repair or replacement of parts of the system must be performed exclusively by qualified installers.

Prior to the installation it is required to download (www.delios-srl.it/download-dlx),
read, understand the step by step instructions from the latest DLX installation manual.
SYMBOLS ADOPTED
The ropes and vehicles used for lifting must be suitable for withstanding the weight of the equipment.
A first aid kit must be provided. Do not underestimate burns or wounds.
The instructions provided in this guidelines do not replace the safety regulations and the installation and operational technical data printed on
the products, nor do they replace the current safety standards enforced in the country where the equipment is installed, and the rules dictated
by common sense.
Other symbols
The notes preceded by this symbol relate to technical issues and ease of operations.
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.
IP21 Protection class rating
A threaded plug fuse cannot be used as a load circuit breaker.
Do not use measuring instruments with a maximum input voltage lower than 1000 V.
During the installation, make sure that the inverter is powered off.
