Safety Instructions
DANGER
Electric shock
Potentially fatal voltages are present in the
inverter during operation. When the inverter
is disconnected from all power sources, this
voltage remains in the inverter for up to 60
seconds.
You should therefore always carry out the fol-
lowing steps before working on the inverter:
1. Turn both DC isolating switches to the
OFF position.
2. Disconnect the inverter from all AC and
DC voltage sources and make sure that
none of the connections can be restored
accidentally.
3. Wait at least 60 seconds for the internal
capacitors to discharge.
DANGER
Electric shock
Potentially fatal voltages are present at the
DC connections of the inverter. When light
falls on the solar modules, they immediately
start to generate electricity. This also hap-
pens when light does not fall directly on the
solar modules.
►Never disconnect the inverter from the
solar modules when it is under load.
►Turn both DC isolating switches to the
OFF position.
►Disconnect the connection to the grid so
that the inverter cannot feed energy into
the grid.
►Disconnect the inverter from all AC and
DC voltage sources. Make sure that
none of the connections can be restored
accidentally.
►Ensure that the DC cables cannot be
touched accidentally.
DANGER
Electric shock
The inverter has a high leakage current
value.
►Always connect the ground cable rst,
then the AC and DC cables.
WARNING
Electric shock
The IP66 protection degree is no longer
guaranteed when the door is open.
►Only open the door when absolutely
necessary.
►Do not open the door if water or dirt might
enter the inverter.
►After work is completed, ensure that the
door is properly shut and tightened again.
Check that the door is properly sealed.
WARNING
Heavy weight
The inverter is heavy.
►Lift and carry the inverter with at least two
people, or use a suitable lifting device.
WARNING
Hot surfaces
The surface of the inverter can get very hot
during operation.
►Always wear safety gloves when touching
the inverter.
NOTICE
Use of aluminum cables
►Always observe the applicable regulations
and rules for the use of aluminum cables.
For detailed information, refer to the com-
plete Installation and Operation Manual.
NOTICE
Working in freezing conditions
In freezing conditions, the rubber seal on the
front door can freeze to the housing and tear
when opened.
►Before opening the front door, defrost the
rubber seal with some warm air.
●To comply with IEC 62109-5.3.3 safety requirements
and avoid injury or material damage, the inverter
must be installed and operated in accordance with
the safety and operating instructions set out in this
manual. Delta Electronics is not responsible for
damage resulting from failure to follow the safety
and operating instructions set out in this manual.
●The inverter may only be installed and commis-
sioned by installers who have been trained and
approved for the installation and operation of grid-
connected solar inverters.
●All repair work on the inverter must be carried out
by Delta Electronics. Otherwise the warranty will be
void.

●Warning notices, warning symbols and other mark-
ings attached to the inverter by Delta Electronics
must not be removed.
●To avoid the risk of arcing, do not disconnect cables
when the inverter is under load.
●To prevent damage due to lightning strikes, follow
the applicable regulations in your country.
●All external connections must be su󰀩ciently sealed
in order to ensure an IP66 protection degree. Seal
any unused connections with the cover caps sup-
plied.
●The covers inside the inverter do not have to be
removed for the standard installation. All connec-
tions required for the standard installation are also
accessible with the covers attached.
●Only equipment in accordance with SELV
(EN 60950) may be connected to the RS485 inter-
faces.
