Quick installation guide for RPI H3 inverters
Connecting to the solar modules (DC)
8
It is recommended to use a spe-
cial open-end spanner for the
MC4 DC connectors if you need
to disconnect MC4 DC connectors
from the inverter. Otherwise you
might destroy the DC connectors.
Ź
To ensure protection degree IP65, cap all
unused connectors with the caps delivered
with the inverter.

DANGER
Risk of death or serious injury from 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 pro-
ducing energy. They do so, even when the sun is not shining directly onto the
solar modules.
Ź
Turn the DC disconnection switch to position
OFF
.
Ź
Never disconnect the solar modules when the solar inverter is powered.
Ź
First switch off the grid connection so that the solar inverter cannot feed
energy into the grid.
Ź
Make sure the DC connections cannot be accidentally touched.
