Installation and operating Instructions
Comment
Distribution to users supplied exclusively via the present grid or the
generator.
This distribution is carried out in conformity with the local standards
and regulations.
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.
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.11
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.
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.
This device (optional) prevents the risk of galvanic corrosion due to
direct currents when a boat is connected at the dock.
