Studer Innotec SAXtenderUser manual V4.6.0 234.5.7 Connecting the AC supply sourcesThe Xtender is intended to be supplied by alternative voltage sources such as the public grid or agenerator. Check that the rated voltage of the source corresponds to the rated voltage (34) of theXtender specified on the nameplate (fig. 1b) tag (34).The source must be connected to the input terminals marked "AC INPUT" (13) with sufficient wire cross-section, depending on the power output of the source, and protected by a protection device of theappropriate calibre. This will be at the maximum 50A for XTH and XTM range and 16A for XTSappliances.The terminals are marked in the following way:N = neutral, L = live= protective earth (connected to the enclosure of the device).4.5.8 Wiring auxiliary contactsThese contacts are reversing contacts that are potential-free available in XTH and XTM units. On XTSmodels, these auxiliary contacts are available on the external auxiliary relay module (accessory)ARM-02 (see sect. 9.5 – p. 37). The admissible currents and voltages for these contacts are 16 A: 250Vac/24Vdc or 3 A: 50 Vdc max. The contact is shown as activated when the corresponding LED is lit.The representation of the contact near the terminals corresponds to the status of the contact whennot activated.The cabling of these auxiliary contracts depends solely on the chosen application and on the specificprogramming applied and cannot be described in this manual.To dedicate/program particular functions to these contacts, please refer to user manual of theremote control unit RCC-02/03The factory-set functions for these 2 auxiliary contacts are covered in the sect. 7.5 – p. 31.Cable-glands that are not in use must be properly closed. If this instruction is not respected,the equipment loses its degree of protection (IP54) and dust or small animals may enter theequipment causing significant damage, which is not covered by the warranty.4.5.9 Connecting the communications cablesThe Xtenders are equipped with a pair of RJ45/8 connectors that allow information transfer via acommunication bus in between devices or accessories that use the proprietary protocol of StuderInnotec. In this network, all parties in the network are connected in series (chain).The length of the communication bus cable must not exceed 300 m.When the Xtender is connected to the remote control RCC-02/-03 or another Xtender compatibledevice (VarioTrack, BSP etc.) it is possible that their software versions differ. It is important to harmonizethe software versions of all Xtender compatible products in a system. The update is made by theremote control RCC-02/-03 from an SD card with a firmware version at least corresponding to themost recent device.An additional earthing terminal (17) is present between the two fastening screws at thebottom of the unit. It can be used instead of a connection on the input terminals of thedevice, particularly when cable cross-sections used at the output do not allow the use of athree-wire cable (live, earth and neutral) through the conduit glands of the connectioncables of the input and output (AC-IN and AC-OUT), or when the earthing of one of thepoles of the battery. PE required using same or greater cross-sections than the batterycable.When connecting the device with other compatible devices (Xtender, VarioTrack, BSP,RCC, Xcom or other) using the same communication bus, it is highly recommended tomake a software update of all components in the system in order to guarantee itsfunctionalities. Therefore, before starting the setup of the device, download the latestsoftware version from our website: www.studer-innotec.com on an SD card. Follow theinstructions in the RCC manual for a successful installation. |
