Studer Innotec SAXtenderUser manual V4.6.0 256 POWERING UP THE INSTALLATIONIt is imperative that the closing cap for the connection compartment (XTM and XTH) andthe XTS enclosure is correctly installed and screwed tight before turning on the power. Thereare dangerous voltages within the interior of the connection compartment.Attention: only a complete tightening of all 4 mounting screws of the XTS enclosureguarantees the IP 54 protection index.The Power up of the Xtender must be carried out in the order given below. Any Power off must becarried out in the reverse order.6.1 CONNECTING THE BATTERY6.2 PUTTING THE XTENDER(S) IN OPERATION USING THE MAIN ON/OFF SWITCH (1) IFPRESENTThe Xtender is supplied and is ready for operation. If you require immediate start-up of the inverterwhen the battery is powered up, the main switch (1) must be in the "ON" position and the parameter{1111} activated. If special configurations or settings are required by the system, it is recommendedto do so immediately according to sect. 5 - p. 24.6.3 CONNECTING THE CONSUMERS AT THE OUTPUTActivate the output protection device (F) if existing, and/or press the ON/OFF button (41). The lightindicator "AC-Out" (46) lights up or flashes (in the event of an absence of consumers).6.4 ACTIVATING THE INPUT CIRCUIT BREAKER(S) (H)If an AC source (generator or electrical grid) valid in frequency and voltage is present at the ACinput, the device automatically goes into transfer and will start to charge the batteries. Theconsumers at the output are therefore supplied directly by the power source present at the input.Your installation is now in operation.A too high or inappropriate battery voltage may seriously damage the Xtender. Forexample, installing a 24 V battery in the Xtender 3000-12.If the Xtender XTH or XTM) has been connected the wrong way around by accident(incorrect polarity of the battery) it is highly likely that the protection fuse on the batterycable may melt and will have to be replaced. If such is the case, it will be necessary todisconnect all the connections to the Xtender including the battery. If, after replacing thefuse, the Xtender proves not to work correctly after reconnecting the battery with thecorrect polarity, it will have to be returned to your distributor for repair.The XTS is electronically protected against reverse polarity. In case of reverse polarityconnection, the unit will remain off. No alarm will signal the fault. It will operate normallyafter recovery of the correct polarity.
