Studer Innotec SAXtenderUser manual V4.6.0 72.3.1 Exclusion of warrantyNo warranty claims will be accepted for damage resulting from handling, usage or processing thatdoes not explicitly appear in this manual. Cases of damage arising from the following causes arenotably excluded from the warranty: Surge voltage on the battery input (for example, 48 V on the battery input of an XTH 3000-12) Incorrect polarity of the battery The accidental ingress of liquids into the device or oxidation resulting from condensation Damage resulting from falls or mechanical shocks Modifications carried out without the explicit authorisation of Studer Innotec Nuts or screws that have not been tightened sufficiently during the installation ormaintenance Damage due to atmospheric surge voltage (lightning) Damage due to inappropriate transportation or packaging Disappearance of original marking elements2.3.2 Exclusion of liabilityThe placement, commissioning, use, maintenance and servicing of the Xtender cannot be thesubject of monitoring by Studer Innotec. Therefore, we assume no responsibility and liability fordamage, costs or losses resulting from an installation that does not conform to the instructions,defective functioning or deficient maintenance. The use of a Studer Innotec inverter is theresponsibility of the customer in all cases.Studer Innotec shall in no event be liable for consequential, incidental, contingent or specialdamages, even if having been advised of the probability of such damages. This equipment is neitherdesigned nor guaranteed to supply installations used for vital medical care nor any other criticalinstallation carrying significant potential damage risks to people or the environment.Studer Innotec assumes no responsibility for the infringement of patent rights or other rights of thirdparties that result from using the inverter.Studer Innotec reserves the right to make any modifications to the product without prior notification.2.4 WARNINGS AND NOTES2.4.1 GeneralThis manual is an integral part of the device and must be kept available for the operatorand installer. It must remain close to the installation so that it may be consulted at any time.The parameter table available at the end of the manual (p. 47) must be kept up to date in the eventof modification of the parameters by the operator or installer. The person in charge of installationand commissioning must be wholly familiar with the precautionary measures and the localapplicable regulations.When the Xtender is running, it generates voltage that can be potentially lethal. Work on orclose to the installation must only be carried out by thoroughly trained and qualifiedpersonnel. Do not attempt to carry out on-going maintenance of this product yourself. TheXtender or the generator connected to it may start up automatically under certainpredetermined conditions.When working on the electrical installation, it is important to be certain that the source ofDC voltage coming from the battery as well as the source of AC voltage coming from agenerator or network have been disconnected from the electrical installation.Even when the Xtender has been disconnected from the supply sources (AC and DC), adangerous voltage may remain at the outputs. To eliminate this risk you must switch theXtender OFF using the ON/OFF button (1). After 10 seconds the electronics is dischargedand intervention may take place without any danger.
