Installation and Operation Manual for RPI M6A M8A M10A inverters V1.0 2016-02-03
6 Installation
6.9 Connecting to the solar modules (DC)
Read chapter “5. Planning the installation”,
p. 19 before you start installation.
DANGER
Risk of death or serious injury from electro-
cution
Potentially fatal voltage may be applied to the
DC connections of the inverter. When light is fall-
ing on solar modules, they immediately start pro-
ducing energy. They do so, even when the sun is
not shining directly onto the solar modules.
► Never disconnect the solar modules when the
inverter is powered.
► First switch off the grid connection so that the
inverter cannot feed energy into the grid.
► Turn the AC/DC Disconnection switch to
position OFF.
► Make sure the DC connections cannot be
accidentally touched.
NOTICE
Improperly sized PV array.
An improperly sized PV array can cause damage
to the inverter.
► Consider the technical specications of the
inverter (input voltage range, maximum cur-
rents and maximum input power, see “13.
Technical data”, p. 113) when planning the
size of the PV array.
NOTICE
Penetrating humidity.
Humidity can penetrate through unused DC con-
nectors into the inverter.
► To ensure protection degree IP65, protect all
unused DC connectors with the caps deliv-
ered with the inverter.
NOTICE
Machine and equipment damage may occur.
Exceeding the maximum current per DC input
can cause an overheating of the DC inputs.
► Always consider the maximum current of the
DC inputs when planning the installation.
Cable colors
Use a red cable for DC+ and a black cable for DC–.
Connector types
The DC plugs are delivered with the inverter. The plugs can also
be ordered from Multi-Contact at www.multi-contact.de. The
required size depends on the wire cross-section and thickness of
the cable used.
DC connector type on the
inverter
Counterpiece required for
the cable
The DC-MINUS connector is a
male socket.
A female plug is required for
the black DC cable.
The DC-PLUS connector is a
male socket.
A male plug is required for the
red DC cable.
You can download the manual from the Multi-Contact website.
This manual will also tell you which tools are required.
France: Safety caps are needed for each
DC input that is connected to a string of
solar modules.
It is recommended to use a special open-
end spanner for the MC4 DC connectors
if you need to disconnect MC4 DC con-
nectors from the inverter. Otherwise you
might destroy the DC Connectors.
