Steca XtenderInstallation and Operating Instructions 723.932 Xtender V0.511 Seite 2910 Figure comment tablesFig. Description and comment1a Dimensioning table for the downstream protection device (F). See chap. 4.5.5 – p. 15.1b Assembly order for connecting the battery.The assembly order for the battery connections must be adhered to. Bolts 20 and 21 areof different sizes: (21): M8x45 for fastening on the fuse(20):M8x35 for fastening without a fuseIf there is no fuse installed, the two bolts are of identical length: M8x35The battery clamp fitted on the fuse (24) must have a diameter of M10 in order to matchthe centering lip of the ceramic isolation disc.Ensure that the battery connections are tightened sufficiently.2a Dimensions and fastening the deviceThe support (wall) must be appropriate for supporting the increased weight of the devicewithout any risk.2b Installation distanceInsufficient distance or an increased ambient temperature can reduce the rated poweroutput of the device.3a Battery charge cycleCharge cycles that are more complex than those described in chap. 6.2.4 – p. 19 of thismanual may be programmed via the RCC-02/03 remote control.Simplified battery charge cycle:See chapter 6.2.4 - p. 19.3c Type plate and series no.See chapter 13 - p. 34.The intactness of this label is vital for any possible warranty claims. It must not be alteredor removed.4a Device connection boxSee chapter 3.6.2 – p. 8.4b Control table See chapter 7.1 - p. 26.5a 12 V battery: connection in series and in parallel / series for 2 V cell5b 12 V battery: connection of 12 V battery in parallel5c 24 V battery: connection in series and in parallel / series for 2 V cell5d 24 V battery: connection in series and in parallel / series for 12 V battery block6a 48 V battery: connection in series and in parallel / series for 12 V battery block6b 48 V battery: connection in series for 12 V battery block6c 48V battery: Series connection of 2V cell6d 48 V battery: connection in parallel / series for 2 V cell7 Xtender circuit diagram8a Single-phase installation (AC and DC part)10.1.1 T HIS EXAMPLE ILLUSTRATES THE MOST ROUTINELY USED INSTALLATION, ALLOWING THEATTAINMENT OF AN EMERGENCY SYSTEM OR A HYBRID SYSTEM ( REMOTE SITES )ENSURING THE SUPPLY IN SINGLE - PHASE FROM A GENERATOR AND/ OR THE BATTERYWHEN THE AC SOURCE IS ABSENT . SEE ALSO CHAPTER 4.1 / GRID- CONNECTEDEMERGENCY SYSTEMS4.1.2 – p. 10.8b ON/OFF remote control variantsThis 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. 6.2.11– p. 23.The maximum length for this control should not exceed 5 m.8c Installation with three-phrase source and secured single-phase output – AC and DCpartIn this example, the three-phase users will only be supplied when the generator is inoperation.
