Basic safety instructions
Inverter
DANGER
Electric shock
Potentially fatal voltages are present at the
inverter during operation. When the inverter
is disconnected from all power sources, this
voltage remains in the inverter for up to 60
seconds.
Therefore, always carry out the following
steps before working on the inverter:
1. Turn the AC/DC disconnector 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 acciden-
tally restored.
3. Wait at least 60 seconds until the internal
capacitors have discharged.
DANGER
Electric shock
Potentially fatal voltages are present at the in-
verter DC connections. When light falls on the
solar modules, they immediately start to gen-
erate electricity. This also happens when light
does not fall directly on the solar modules.
► Never disconnect the inverter from the
solar modules when it is under load.
► Turn the AC/DC disconnector to the OFF
position.
► Disconnect the connection to the mains so
that the inverter cannot supply energy to
the mains.
► Disconnect the inverter from all AC and
DC voltage sources. Ensure that none of
the connections can be restored acciden-
tally.
► Ensure that the DC cables cannot be
touched accidentally.
●
To comply with the IEC 62109-5.3.3 safety require-
ments 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 be installed and commissioned only
by installers who have been trained and certified for
the installation and operation of mains-based solar
inverters.
●
All repair work on the inverter must be carried out
by Delta Electronics. Otherwise, the warranty will be
void.

●
Warning instructions and warning symbols attached
to the inverter by Delta Electronics must not be re-
moved.
●
The inverter has a high leakage current value. The
grounding cable must be connected before com-
mencing operation.
●
Do not disconnect any cables while the inverter is
under load due to risk of a fault arc.
●
To prevent damage due to lightning strikes, follow the
provisions that apply in your country.
●
The surface of the inverter can get very hot during
operation. Wear safety gloves when you touch the
inverter (apart from at the display).
●
Only equipment in accordance with SELV (EN 60950)
may be connected to the RS485 interfaces.
●
All connections must be sufficiently insulated in order
to ensure the IP65 degree of protection. Unused con-
nections must be closed using cover caps.
