Description and comment
1a
Dimensioning table for the downstream protection device (F).
This table helps to size the Xtender upstream and downstream protection devices. Due to
the source assistance function, it should be outlined that the downstream protection can be
of higher gauge than the upstream one.
1b
Type plate and series no.
See sect. 19 - p. 46.
It is vital that this label is intact for any possible warranty claims. It must not be altered or
removed.
2a
Dimensions and fastening the device
The support (wall) must be appropriate for supporting the increased weight of the device
without any risk.

Xtender XTS circuit diagram
This diagram shows the major electrical components, control elements and their interaction
in XTS model, for proper understanding of the operating principle of the device.
7b
Xtender XTH/XTM circuit diagram
This diagram shows the major electrical components and control elements and their
interaction in XTH and XTM model, for proper understanding of the operating principle of the
device.
8a
Single-phase installation (AC and DC part)
This example illustrates the most routinely used installation; that of an emergency system or a
hybrid system (remote sites) ensuring the supply in single-phase from a generator and/or the
battery when the AC source is absent. See also sect. 4.1.1– p. 16.
8b
Remote entry variants (ON/OFF remote control)
This example illustrates the various possibilities for connecting the remote entry (remote
ON/OFF on former version) terminal block (7), enabling the control of the programmed
function (See also sect. 7.7 - p. 31.) with a dry contact or a voltage source (max 60V
eff./30mA). The maximum wire length on this control should not exceed 10 m.
8c
Installation with three-phrase source and secured single-phase output – AC and DC part
In this example, the three-phase users will only be supplied when the generator or grid are
operating.
9a
Fixed installation with plug connection to the single-phase source – AC part
Special feature: The connection of the neutral upstream and downstream of the Xtender (C) is
prohibited in this configuration (presence of a plug upstream). See also sect. 4.2 – p. 17.
9b
Fixed single-phase installation with connection by plug to a three-phase source – AC part
Highlight(s): The connection of the neutral upstream and downstream of the 'Xtender (C) is
prohibited in this configuration (presence of a plug upstream). See also sect. 4.2 – p. 17.
10a
Example of installation in a vehicle (AC part)
Highlight(s): The connection of the neutral (C) is not permitted (presence of a socket
upstream). The earth-neutral connection is absent in inverter mode (neutral stand-alone
system). Safety is guaranteed by the equipotential bonding (frame). The automatic re-
establishment of the earth-neutral connection downstream of the device in inverter mode
can be programmed. Consult the table of figures, item (V). See also sect.
4.2.3
– p. 18
.
10b
Example of installation in a boat without an isolation transformer (AC part)
Highlight(s): Where there are multiple sources, for example connection to the dock and on-
board generator, a source reverser (X) guaranteeing switching with phase and neutral
interruption must be installed.
