POWERING UP THE INSTALLATION
It is imperative that the closing cap for the connection compartment (XTM and XTH) and
the XTS enclosure is correctly installed and screwed tight before turning on the power. There
are dangerous voltages within the interior of the connection compartment.
Attention: only a complete tightening of all 4 mounting screws of the XTS enclosure
guarantees the IP 54 protection index.
The Power up of the Xtender must be carried out in the order given below. Any Power off must be
carried out in the reverse order.

IF
PRESENT
The Xtender is supplied and is ready for operation. If you require immediate start-up of the inverter
when 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 recommended
to do so immediately according to sect. 5 - p. 24.

ONNECTING THE CONSUMERS AT THE OUTPUT
Activate the output protection device (F) if existing, and/or press the ON/OFF button (41). The light
indicator "AC-Out" (46) lights up or flashes (in the event of an absence of consumers).

CTIVATING THE INPUT CIRCUIT BREAKER

(H)
If an AC source (generator or electrical grid) valid in frequency and voltage is present at the AC
input, the device automatically goes into transfer and will start to charge the batteries. The
consumers 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. For
example, 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 battery
cable may melt and will have to be replaced. If such is the case, it will be necessary to
disconnect all the connections to the Xtender including the battery. If, after replacing the
fuse, the Xtender proves not to work correctly after reconnecting the battery with the
correct polarity, it will have to be returned to your distributor for repair.
The XTS is electronically protected against reverse polarity. In case of reverse polarity
connection, the unit will remain off. No alarm will signal the fault. It will operate normally
after recovery of the correct polarity.
