Studer Innotec SAXtenderUser manual V4.6.0 4215 COMMENTS TO DRAWINGS IN THE APPENDIXFig. Description and comment1aDimensioning table for the downstream protection device (F).This table helps to size the Xtender upstream and downstream protection devices. Due tothe source assistance function, it should be outlined that the downstream protection can beof higher gauge than the upstream one.1bType plate and series no.See sect. 19 - p. 46.It is vital that this label is intact for any possible warranty claims. It must not be altered orremoved.2aDimensions and fastening the deviceThe support (wall) must be appropriate for supporting the increased weight of the devicewithout any risk.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 cell7aXtender XTS circuit diagramThis diagram shows the major electrical components, control elements and their interactionin XTS model, for proper understanding of the operating principle of the device.7bXtender XTH/XTM circuit diagramThis diagram shows the major electrical components and control elements and theirinteraction in XTH and XTM model, for proper understanding of the operating principle of thedevice.8aSingle-phase installation (AC and DC part)This example illustrates the most routinely used installation; that of an emergency system or ahybrid system (remote sites) ensuring the supply in single-phase from a generator and/or thebattery when the AC source is absent. See also sect. 4.1.1– p. 16.8bRemote entry variants (ON/OFF remote control)This example illustrates the various possibilities for connecting the remote entry (remoteON/OFF on former version) terminal block (7), enabling the control of the programmedfunction (See also sect. 7.7 - p. 31.) with a dry contact or a voltage source (max 60Veff./30mA). The maximum wire length on this control should not exceed 10 m.8cInstallation with three-phrase source and secured single-phase output – AC and DC partIn this example, the three-phase users will only be supplied when the generator or grid areoperating.9aFixed installation with plug connection to the single-phase source – AC partSpecial feature: The connection of the neutral upstream and downstream of the Xtender (C) isprohibited in this configuration (presence of a plug upstream). See also sect. 4.2 – p. 17.9bFixed single-phase installation with connection by plug to a three-phase source – AC partHighlight(s): The connection of the neutral upstream and downstream of the 'Xtender (C) isprohibited in this configuration (presence of a plug upstream). See also sect. 4.2 – p. 17.10aExample of installation in a vehicle (AC part)Highlight(s): The connection of the neutral (C) is not permitted (presence of a socketupstream). The earth-neutral connection is absent in inverter mode (neutral stand-alonesystem). Safety is guaranteed by the equipotential bonding (frame). The automatic re-establishment of the earth-neutral connection downstream of the device in inverter modecan be programmed. Consult the table of figures, item (V). See also sect. 4.2.3 – p. 18.10bExample of installation in a boat without an isolation transformer (AC part)Highlight(s): Where there are multiple sources, for example connection to the dock and on-board generator, a source reverser (X) guaranteeing switching with phase and neutralinterruption must be installed. |
