Elem.	Description		Comment
A	Input supply cable		The section is determined by means of the maximum current at
			source and the protection device (H). In multi-unit systems, cables (A)
			of the same phase must have the same length and section (see
			comment fig. 12-2/3).
B	Output	supply	In multi-unit systems, cables (B) of the same phase must have the
	cable		same length and section (see comment fig. 12-2/3). The section must
			be selected by means of the Xtender’s output current given on the
			type plate and the protection device selected for the input (see fig.
			1a).
C	Connection of the		See chapter 4.2 - p. 10.
	neutrals		In a fixed installation where the neutral is connected to the earth at a
			single installation point upstream of the Xtender, it is permissible to
			carry out a connection of the neutrals in order to preserve an
			unchanged earthing system downstream, independent of the
			operating mode of the Xtender. This choice shows the advantage of
			keeping the differential protection devices downstream of the
			Xtender.
			This connection (C) is not permitted if a socket is installed upstream
			of the Xtender.
D	Differential	circuit	A protection device must be installed downstream of he source (G or
	breaker		U) according to the local requirements and in compliance with the
			applicable regulations and standards.
E	Earth-neutral		The neutral is earthed at a single point of the installation, downstream
	connection bridge		of the source and upstream of the protection device(s) at the default
			current (DDR). When several sources are available, each source must
			have an earthed neutral. If the source has to be retained with an
			isolated earthing system (IT) the applicable local provisions and
			regulations must be applied.
F	AC	output	A protection device dimensioned in dependence of the cable section
	protection devices		used may be installed downstream of the Xtender (main circuit
	for the Xtender		breaker before distribution). The cable section is to be dimensioned
			according to the calculation table of maximum output current (fig. 1).
			The Xtender has an internal current limitation the value of which is
			stated on the type plate Fig. 1b (35).
G	Generator		The generator is dimensioned according to the requirements of the
			user. Its rated current will determine the configuration adjustment
			{1107} “maximum current of the AC source”.
H	Protection devices		The protection device at the input of the Xtender must be
	at the	Xtender	dimensioned according to the power output of the source at the
	input		cable section used. It will not exceed a calibre equivalent to the input
			current “I AC in” given on the type plate of the unit Fig. 1b (35).
J
K	Connection plug /		If the Xtender is connected to an AC source by means of a plug, the
	socket		connection cable must not exceed a length of 2 m, and the socket
			must remain permanently accessible. The socket will be protected by
			a protection device of appropriate calibre. The connection of the
			neutrals (C) is prohibited in this case.

R
S	Secured grid		Distribution to the users supplied by the grid or the generator when
			this is present or by the Xtender within the limit of its power output
			from energy stored in the battery. This distribution is carried out in
			conformity with the local standards and regulations.
