5.3. ELECTRIC CONNECTION.

An excessively high voltage on the conductive part of
the inverter may cause electric shock. When installing
the inverter, make sure that the AC and DC sides of the
Danger
inverter are completely de-energised.
Do not connect the positive or negative poles of the
photovoltaic panel to earth, since this may cause major
Warning
damage to the inverter.
Static electricity can damage the inverter's electronic
components. Take the necessary anti-static measures
Warning
during installation and maintenance.
Do not use terminals of different manufacturers or of
different types, other than those included in the
accessory pack. SALICRU shall not be held liable for any
Attention
form of damage caused by the use of unauthorised terminals.
Moisture and dust can damage the inverter; check that
the cable gland is tight enough during installation.
The warranty will be void if the inverter is damaged as
Attention
a result of an improperly installed cable gland.
5.3.1. External earthing connection.
Do not connect the neutral N wire as a protective
earthing wire to the inverter housing. This may cause
Danger electric shock.
An optimal earthing connection can withstand resist surge
discharges and improve EMI performance. Inverters must
Attention be properly earthed.
For systems with a single inverter, the PE wire must
be earthed.
For a multi-inverter system, all PE cables from the
inverters must be connected to the same copper earthing
bar to ensure equipotential bonding.
Steps for connecting the terminal to earth:
1.
The external earthing connection terminal is located on the
lower right side of the inverter.
2.
Fasten the earthing connection terminal to the PE cable with
a suitable tool and lock the earthing connection terminal to
the earthing connection hole on the bottom right side of the
inverter as shown in Fig. 19, Fig. 20, Fig. 21.
3.
The cross-sectional area of the external earthing wire is 4 mm .
