Xtender 

 

12 V.3.1.0 

User 

manual 

The Xtender can be operated with any earthing system. In all cases it is imperative that the 

protective earth be connected in compliance with the applicable standards and regulations. The 
information, notes, recommendations and diagram mentioned in this manual are subject to local 

installation regulations in every case. The installer is responsible for the conformity of the installation 

with the applicable local standards. 

4.2.1

 

Mobile installation or installation connected to the grid via plug 

connector 

When the input of the device is connected directly to the grid via a plug, the length of the cable 

must not exceed 2 m and the plug must remain accessible. 
In the absence of voltage at the input, the neutral and live are interrupted, thereby guaranteeing 

complete isolation and protection of the cabling upstream of the Xtender. 

The earthing system downstream of the Xtender is determined by the upstream earthing system 
when the grid is present. In the absence of the grid, the earthing system downstream of the inverter 

is in isolated mode. The safety of the installation is guaranteed by the equipotential bonding. 

 

The connection (link) between the neutrals (C) upstream and downstream of the 

Xtender is not permitted in this configuration. 

 

This connection type guarantees the optimal continuity for supplying the Xtender loads. The first 
isolation fault will not lead to an interruption in the supply. 

If the installation requires the use of a permanent isolation controller this would have to be de-

activated when the TT network is present at the Xtender input. 
 

All sockets and protection class I devices connected downstream of the Xtender must 

be properly connected to the earth (earthed socket). The cabling rules above remain 
valid, including in installations, in all cases where the Xtender input is connected to the 

grid via a plug connector. 

4.2.2

 

Stationary installation 

The installation may be equivalent to a mobile installation (with interrupted neutral).  

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 has the advantage of keeping the protection devices downstream of the 

Xtender.  This connection can be executed according to the examples in appendix 1, or carried 
out by modifying the configuration {1486} 

In this case the appearance of the first fault will lead to the installation stopping or the 

disconnection of the protection devices upstream and/or downstream of the Xtender. 
Safety is guaranteed by the equipotential bonding and by any RCD circuit-breakers placed 

downstream. 

This connection (C) is not permitted if a socket is installed upstream of the Xtender. 

4.2.3

 

Installation with automatic PE-neutral switching 

In certain applications, it is desirable to keep the neutral upstream and downstream of the Xtender 
separated (C) while re-establishing the earthing system (TN-S, TT or TNC-S) in the absence of voltage 

at the input. This can be programmed by the configuration {1485} via the RCC-02/03 remote 

control. This modification must be carried out possessing technical knowledge, at the responsibility 
of the installer and in conformity with the applicable regulations and standards. 

This allows adherence to the requirements for an earth-neutral connection at the source.
