INSTALLATION
�
�. The walls must be fireproof and non-flammable materials, otherwise there is a fire risk.
�. Before drilling holes, check whether there are electric power pipes or other pipes buried in the walls to avoid risks.
Set bracket horizontally.

GROUNDING
�
�. According to regulations, the secondary protection grounding can' t replace the PE terminal connection of
the AC cable. Ensure that both are grounded reliably.
�. Ensure that inverter and all cables to be installed are completely powered off during whole installation and
connection. Otherwise, fatal injury can occur due to the high voltage.

PV CONNECTION
�
�.Photovoltaic arrays exposed to sunlight will generate dangerous voltages!
�.Before connecting the DC terminal, ensure that both the AC terminal and the DC terminal
are powered off and the DC switch is OFF. Otherwise there is a risk of high voltage shock.

DC cable should be dedicated PV cable (suggest using �~�mm² PV�-Fcable).
Note:
Before connecting the AC terminal, ensure that both the AC terminal and the DC terminal are
powered off and the DC switch is OFF. Otherwise there is a risk of high voltage shock.
