Steca Xtender 2.3 Quality and warranty During the production and assembly of the Xtender, each unit undergoes several checks and tests. These are carried out with strict adherence to the established procedures. Each Xtender has a serial number allowing complete follow-up on the checks, according to the particular data for each device. For this reason it is very important never to remove the type plate (appendix I – fig. 3b) which shows the serial number. The warranty for this equipment d

Steca Xtender DC voltage coming from the battery as well as the source of AC voltage coming from a generator or network have been disconnected from the electrical installation. Even when the Xtender has been disconnected from the supply sources (AC and DC), a dangerous voltage may remain at the outputs. To eliminate this risk you must switch the Xtender OFF using the ON/OFF button (1). After 10 seconds the electronics is discharged and intervention may take place without any danger. A

Steca Xtender 4.1 Choice of system The Xtender may be used in different system types, each of which must meet the standards and particular requirements associated with the application or site of installation. Only an appropriately qualified installer can advise you effectively on the applicable standards with regard to the various systems and the country concerned. Examples of cabling are presented in appendix I of this manual, fig. 5 and following. Please carefully read the notes asso

Steca Xtender 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

Steca Xtender 4.3 Recommendations for dimensioning the system 4.3.1 DIMENSIONING THE BATTERY The battery capacity is dimensioned according to the requirements of the user – that is 5 to 10 times its average daily consumption. The discharge depth of the battery will therefore be limited and the service life of the battery will be extended. On the other hand, the Xtender must have a battery capacity that is large enough to be able to take full advantage of the performance of the equipment

Steca Xtender 4.5 Connecting the battery Lead batteries are usually available in 2 V, 6 V or 12 V block types. In the majority of cases, in order to obtain an operating voltage that is correct for Xtender usage, several batteries must be connected in series or in parallel depending on the circumstances. . In multi-unit systems, all Xtenders from the same system must be connected according to the same battery bank. The various cabling options are presented in figures 5a-5b (12 V

Steca Xtender BATTERY-SIDE CONNECTION 4.5.3 Before connecting the battery, carefully check the voltage and polarity of the battery using a voltmeter. Incorrect polarity or surge voltage may seriously damage the device. Prepare the batteries for connection: appropriate battery clamps, protection device (f), cable in good conditions with correctly fitted clamps. Fasten the black cable on to the negative pole (-) of the battery and the red cable on the open protection device (f).

Steca Xtender EARTHING THE BATTERY 4.5.4 One of the two battery conductors can be earthed. This may be either the positive or negative pole. In all cases the installation must conform to the local regulations and usage or specific standards associated with the application. In case of earthing, the earthing conductor section must at least be equivalent to the section of the battery conductor. The earthing of the equipment must also adhere to these regulations. In this case the use of th

Steca Xtender 4.5.6 CONNECTING THE AC SUPPLY SOURCES The Xtender is intended to be supplied by alternative voltage sources such as the public grid or a generator. Check that the rated voltage of the source corresponds to the rated voltage (34) of the Xtender specified on the type plate (fig. 3b). The source must be connected to the input terminals marked “AC INPUT” (13) with sufficient wire section, depending on the power output of the source, and protected by a protection device of the
