Studer Innotec SAXtenderUser manual V4.6.0 51 INTRODUCTIONCongratulations! You are about to install and use a device from the Xtender range. You have chosena high-tech device that will play a central role in energy saving for your electrical installation. TheXtender has been designed to work as an inverter / charger with advanced functions, which can beused in a completely modular way and guarantee the faultless functioning of your energy system.When the Xtender is connected to a generator or network, the latter directly supplies the consumers,and the Xtender works like a battery charger and backup device if necessary. The powerful batterycharger has an exceptionally high efficiency and a power factor correction (PFC) close to 1. Itguarantees excellent battery charging in all situations. The charge profile is freely configurableaccording to the type of battery used or the method of usage. The charge voltage is correcteddepending on the temperature, thanks to the optional external sensor. The power of the charger ismodulated in real time dependent according to the demand of the equipment connected at theXtender output and the power of the energy source (network or generator). It can even temporarilybackup the source if the consumer demand exceeds the source capacity.The Xtender continuously monitors the source to which it is connected (network or generator) anddisconnects itself immediately if the source is missing, disturbed or does not correspond to the qualitycriteria (voltage, frequency, etc.). It will then function in independent mode, thanks to the integratedinverter. This inverter, which has an extremely robust design, benefits from Studer Innotec’s manyyears of experience and expertise in this area. It could supply any type of load without faults, enjoyingreserves of additional power that is unmatched in the market. All your equipment will be perfectlyprovided with energy and protected from power outages in systems where energy supply isunpredictable (unreliable network) or voluntarily limited or interrupted, such as hybrid installations onremote sites or mobile installations.The parallel and/or three-phase network operation of the Xtender offers modularity and flexibility andenables optimum adaptation of your system to your energy requirements.The RCC-02/-03 control, display and programming centre (optional) enables optimum configurationof the system and guarantees the operator continuous control for all important parameters in theinstallation.In order to guarantee flawless commissioning and functioning of your installation, please read thismanual carefully. It contains all the necessary information relating to the functioning of theinverters/chargers in the Xtender series. The setting up of such a system requires special expertise andmay only be carried out by qualified personnel familiar with the applicable local regulations.2 GENERAL INFORMATION2.1 OPERATING INSTRUCTIONSThis manual is an integral part of each inverter/charger from the Xtender series.It covers the following models and accessories1:Inverter/charger:XTH 3000-12 – XTH 5000-24 – XTH 6000-48 – XTH 8000-48XTM 1500-12, XTM 2000-12, XTM 2400-24,XTM 3500-24, XTM 2600-48, XTM 4000-48XTS 900-12, XTS 1200-24, XTS 1400-48External cooling fan: ECF-01Temperature sensor: BTS-01Remote command module: RCM-10Auxiliary relay module: ARM-02For greater clarity, the device is referred to in this manual as Xtender, unit or device, when thedescription of its functioning applies indiscriminately to different Xtender models.These operating instructions serve as a guideline for the safe and efficient usage of the Xtender.Anyone who installs or uses an Xtender can rely completely on these operating instructions, and isbound to observe all the safety instructions and indications contained.
