DLS / DLS-C Series
57
Cod.: 240.010.0042
For safety reasons and according to the regulations in force in the country of installation it is necessary to
provide an appropriately rated external RCD protection device for the home loads line and for the privile-
ged loads line. No load should be connected directly to the DLS inverter.
The power losses on the AC OUT line must be less than 1% of the rated power. The indicative data of the
connection are reported below.

WARNING: The total power of the loads connected to the AC OUT output must be within the range
specied in the technical data. During EPS or SMART ISLAND operating mode, if the total load is higher,
the DLS will enter in protection mode, disabling the output power and signaling the overload event. After a
few seconds it will attempt to restore the regular operation of the AC OUT port. This restart mode will conti-
nue until the total load connected to the AC OUT port is compatible with the maximum rat-ings specied in
the technical data. It is therefore recommended to connect only essential loads to the AC OUT port
WARNING: In EPS or SMART ISLAND mode, some loads may not work properly even if their total rated
power is within the limits specied in the technical data. This can happen because the inrush currents could
be too high (refrigerators, air conditioners, hydraulic pumps, etc.). In these cases, the DLS hybrid inverter
will enter in protection mode, disabling the output power and signaling the overload event. After a few se-
conds it will attempt to restore the regular operation of the AC OUT port. This restart mode will continue
until the total load connected to the AC OUT port is compatible with the maximum rat-ings specied in the
technical data. It is therefore recommended to connect only essential loads to the AC OUT port.
5.5 LV Lithium Battery Connection
Before connecting the battery to the DLS system, make sure to have read and understood all the instruc-
tions provided in the operating and installation manual supplied by the battery manufacturer. Failure to
follow the instructions provided in this manual may affect the correct operation of the system, lead to poten-
tially hazardous situations, relieves DELIOS s.r.l. from any liability and invalidates the warranty conditions.
Contact the DELIOS s.r.l. or consult the website www.delios-srl.it to identify the supported batteries.
WARNING: The default factory setting of the DLS is set to operate without any battery connected
to the system. To enable HV battery operation, access the "SETTINGS" conguration menu in INSTAL-
LER mode, access the "BATTERY" menu and select the correct LV battery model from those listed in the
"LITHIUM" menu. Refer to the SYSTEM PROGRAMMING section.
See the connection instructions shown in Figure 13.
