Quick installation guide for solar inverters RPI M6A M8A M10A EU V4 EN 5013221703 00 2017-11-16
Basic safety instructions
● To comply with the 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 Energy
Systems is not responsible for damage resulting from fail-
ure to follow the safety and operating instructions set out in
this manual.
● The inverter may only be installed and commissioned by
installers who have been trained and certied for the instal-
lation and operation of grid-based solar inverters.
● All repair work on the inverter must be carried out by Delta
Energy Systems. Otherwise, the warranty will be void.
● Warning instructions and warning symbols attached to the
inverter by Delta Energy Systems must not be removed.
● The inverter has a high leakage current value. The ground-
ing cable must be connected before commencing opera-
tion.
● 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 provi-
sions that apply in your country.
● The surface of the inverter can get very hot during opera-
tion. 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 sufciently insulated in order to
ensure the IP65 degree of protection. Unused connections
must be closed using cover caps.
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 accidentally
restored.
3. Wait at least 60 seconds until the internal
capacitors have discharged.
DANGER
Electric shock
Potentially fatal voltages are present at the
inverter DC connections. When light falls on the
solar modules, they immediately start to gener-
ate 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 grid so
that the inverter cannot supply energy to
the grid.
► Disconnect the inverter from all AC and DC
voltage sources. Ensure that none of the
connections can be restored accidentally.
► Ensure that the DC cables cannot be
touched accidentally.
ATTENTION
Damage through an incorrectly dimensioned
solar system.
An solar system of the wrong size may cause
damage to the inverter.
► Always pay attention to the technical speci-
cations of the inverter (input voltage range,
maximum current and maximum input
power) when calculating the number of solar
modules.
ATTENTION
Overheating of the DC connections.
Exceeding the maximum current can cause
overheating of the DC connections and result in
a re.
► Always take into account the maximum cur-
rent of the DC connections when planning
the installation.
