Installation guide for solar inverters RPI M6A M8A M10A EU V5 EN 2022-08-15
DANGER
Electric shock
Potentially fatal voltages are present at the
DC connections of the inverter. When light
falls on the solar modules, they immedia-
tely start to generate electricity. This also
happens when light does not shine 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 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 resto-
red accidentally.
► Ensure that the DC cables cannot be
touched accidentally.
ATTENTION
Ingress of moisture.
Moisture can enter via open DC connecti-
ons.
► To ensure protection degree IP65, close
unused DC connections with the rubber
plugs attached to the DC connections.
Polarity of the DC voltage
► Check the polarity of the DC voltage of the DC strings
before connecting the solar modules.
Tools
The protective caps lock the DC plug
so that it can only be disconnected
from DC connections using the moun-
ting tool.
► Observe the local regulations with
regards to the protective caps.
France: The protective caps must be
used.
Mounting tool for disconnecting the
DC plug and the protective caps from
the DC connections. Available from
Multi-Contact.
Connecting the DC cables
1. Turn the AC/DC disconnector to the OFF position.
2. Remove the sealing caps from the DC connections
and store in a safe place. Do not remove the sealing
caps from the unused DC connections.
3. Plug the DC plugs with the DC cables into the DC con-
nections on the inverter.
→ The installation should look like the following illu-
stration.
