vehicles and leisure vehicles. In these cases, two separate AC inputs are often required, one connected to the grid and the other connected to an on-board generator. Switching between two sources must be carried out using an automatic or manual reversing switch, conforming to the applicable local regulations. The Xtender has a single AC input.

Various application examples are described in figs. 10a – 10b – 10c).

4.1.4MULTI-UNIT SYSTEMS

Whatever system is selected, it is possible to realise systems composed of several units of the same type and the same power output. Up to three Xtenders in parallel or three extenders forming a three-phase grid or three times two with three Xtenders in parallel forming a three-phase / parallel grid, may be thus combined.

4.2 Earthing system

The Xtender is a protection class I unit, which is intended for cabling in a grid type TT, TN-S or TNC- S. The earthing of the neutral conductor (E) is carried out at a sole installation point, upstream of the RCD circuit breaker (D).

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.

4.2.1MOBILE 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 fixed installations, in all cases where the Xtender input is connected to the grid via a plug connector.

4.2.2FIXED 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.
