Fig. Description and comment
1a
Dimensioning table for the downstream protection device (F). See chap. 4.5.6 – p.14.
1b
Type plate and series no.
See chapter 16 - p. 32.
The intactness of this label is vital 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.
2b
Installation distance
Insufficient distance or an increased ambient temperature can reduce the rated power
output of the device.
3a
Battery charge cycle
Charge cycles that are more complex than those described in chap. 6.2.4 – p. 17 of this
manual may be programmed via the RCC-02/03 remote control
.

7 Xtender circuit diagram
8a Single-phase installation (AC and DC part)
This example illustrates the most routinely used installation, allowing the attainment 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 chapter
4.1.1.1 / 4.1.2 – p. 9.
8b ON/OFF remote control variants
This example illustrates the various options for connecting the “REMOTE ON/OFF” input
(7), enabling the ON and OFF controls of the Xtender via a contact or a voltage source.
See also chap. 6.2.12 – p. 21.
The maximum length for this control should not exceed 5 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 chapter 4.2.1
– p. 10.
9b Fixed single-phase installation with connection by plug to a three-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 chapter 4.2.1
– p. 10.
