U Public grid
The connection to the public grid imposes adherence to the local
standards and regulations at the responsibility of the installer. The
installation should, in principle, be checked and approved by an
official body.
V
Automatic
earth-neutral
connection
This connection is deactivated by default. In may be used in certain
specific cases for automatically re-establishing the neutral system type
TT (TNC, TNS, TNC-S) when the Xtender is in inverter mode. The
activation is carried out via RCC-02/03 remote control configuration
{1485}. This operation may only be carried out by qualified personnel,
under the responsibility of these personnel, and in conformity with the
local standards and regulations. See 4.2.3– p.12
W
Galvanic
isolator
This device (optional) is generally used to reduce the risk of electrolytic
corrosion due to the direct current when a boat is connected at the
dock.
X
Source
reversing
switch
When the installation has more than one supply source, it is necessary
to install a switching device between the sources, simultaneously
switching the neutral and the phase(s) of these sources. In all cases this
device (manual or automatic) must guarantee interruption of the
connected source before its connection to another source.
Y
Isolation
transformer
This device (optional) prevents the risk of galvanic corrosion due to
direct currents when a boat is connected at the dock.
