General safety instructions
1
High electrocution
Potentially fatal voltage is applied to the solar
inverter during operation. This potentially fatal
voltage is still present for 15 seconds after all
power sources have been disconnected.
Never open the inverter.
Always disconnect the inverter from
power before installation, open the DC
disconnection switch and make sure neither
can be accidentally reconnected.
Wait at least 15 seconds until the capacitors
have discharged.
High electrocution
Potentially fatal voltage may be applied to the
DC connections of the solar inverter. When light
is falling on solar modules, they immediately start
producing energy. They do so, even when the
sun is not shining.
Never disconnect the solar modules when the
solar inverter is powered.
First switch off the grid connection so that
the solar inverter cannot feed energy into the
grid.
Turn the DC disconnection switch to position
.
Make sure the DC connections cannot be
accidentally touched.
Read this quick installation guide before you start installing
the inverter.
The inverter can safely and normally be operated if installed
and used in accordance with this manual (see IEC 62109-
5.3.3). Delta Energy Systems is not responsible for damage
incurred by failure to observe the installation and commis-
sioning instructions in this manual. For this reason, be sure
to observe and follow all instructions!
Installation and commissioning may only be performed by
-
ing instructions found in this manual.
The inverter must be disconnected from power and the solar
modules before any work on it can be performed.
The inverter has a high leakage current value. The ground
wire must be connected before commissioning.
Do not remove any warning signs that the manufacturer has
installed on the solar inverter.
Improper handling of the inverter may result in physical injury
and damage to property. For this reason, observe and follow
all general safety instructions and warnings.
The inverter contains no components that must be main-
tained or repaired by the operator or installer. All repairs must
be performed by Delta Energy Systems. Opening the cover
will void the warranty.
Do not disconnect any cables when the solar inverter is pow-
ered due to risk of a fault arc.
To prevent lightning strikes, follow the relevant regulations
applicable in your country.
The surface of the solar inverter can become very hot dur-
ing operation. Use safety gloves when working on the solar
inverter.
Only devices in compliance with SELV (EN 69050) may be
connected to the RS485 interfaces.
-
ply with the IP65 protection rating. Unused connections must
be closed by placing cover caps on the solar inverter.

Risk of death by electrocution
Potentially fatal voltage is present when the solar inverter is in operation that remains for 15 seconds after being
disconnected from power.
Never open the solar inverter. The solar inverter contains no components that must be maintained or repaired by
the operator or installer. Opening the cover will void the warranty.
Read the manual delivered with the inverter before working with the solar inverter and follow the instructions
contained in the manual.
The housing of the inverter must be grounded if this is required by local regulations.
Regulatory Compliance Mark (RCM mark): The inverter is compliant with the Australian Electrical Safety and
EMC standards. Applies only to Australia and New Zealand.

Do not install inverters directly above one another.
Otherwise, the upper inverter is warmed up by the
lower one.
Consider the operating temperature range (see

For the safety of the user and for the security of your installation,

dance with DIN VDE 0100-712.
When examining these possible fault situations in terms of the
currently valid installation standards, Delta has come to the
conclusion that there is no danger when operating the inverter
in combination with a type A upstream residual-current device
(RCD).
Therefore faults that would otherwise require the use of a type B
residual-current device due to the inverter can be excluded.
The integrated all-pole sensitive RCMU provides additional
safety. RCD Type A can be used for this inverter, according to the
following table.
Minimum tripping current of the RCD 30 mA *
Table: Recommended RCD Type A for a single inverter
* see description in the note below
The value of the tripping current mainly depends
on the installation of the PV generator, the size of
the PV array and environmental conditions (e.g.
humidity).

France: Safety caps are needed for each
DC input that is connected to a string of
solar modules. To remove the safety caps,
a open-end spanner is needed.
It is recommended to use a special open-
end spanner for the MC4 DC plugs if you
need to disconnect MC4 DC plugs from
the inverter. Otherwise you might destroy
the DC plugs.

If you need to wire dry contacts, digital inputs
or RS485, it is recommended to do this in a dry
environment and before you hang the inverter
onto the wall.
Reasons for this are:
You will have to remove the covers from the
connection ports. Water could leak into the
inverter.
The terminal blocks inside are not easily
accessible.

RS485 is used to connect the inverters of the PV plant via a data-
logger to a monitoring system.
For connecting RS485, terminals 3/4 or 5/6 are used. It does not
matter which pair of terminals you use. The second pair you only
need when you connect multiple inverters via RS485.
If you want to use SOLIVIA Monitor, the Internet based monitor-
ing from Delta, you will also need a SOLIVIA M1 G2 Gateway.
Default baud rate is 19200 which can be changed on the inverter
(see chapter “Setting the baud rate”, p. 19).

When your grid operator wants you to set a
power limitation, e.g. for the 70% regulation in
Germany, you need the Delta Service Software,
which is available from Delta.
If you need to wire dry contacts, digital inputs or
RS485, it is recommended to do this in a dry en-
vironment and before you hang the inverter onto
the wall. Reasons for this are:
You will have to remove the covers from the
connection ports. Water could leak into the
inverter.
The terminal blocks inside are not easily

When the inverter is feeding into the grid, the dry contact is
closed.
If you want to use a PC with the Delta Service Software to set up
the inverter, you need a USB/RS485 adapter to connect the PC
to the RS485 terminal block of the inverter.
The USB/RS485 adapter is available from Delta.
