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 | ||
|
|
| of the same phase must have the same length and section (see | ||
|
|
| comment fig. |

B | Output | supply | In | ||

| same length and section (see comment fig. | ||
|
|
| 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 | 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. |

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. |
