User manual V.3.2.0 15
The clamps must be carefully fixed and tightened sufficiently to guarantee minimum loss.
Insufficient tightening may cause dangerous heating at the connection point.
For safety reasons, we recommend an annual check on the tightness of all connections.
For mobile installation the connections should be checked more frequently for tightness.
4.5.2
Connecting the battery (Xtender side)
Insert the conduit glands supplied on the battery cable before tightening the cable clamp. Crimp
the cable clamps and fasten the conduit gland on the device. Repeat this for the second battery
cable. Fix the battery cables to the appropriate connections „+ Battery “and „- Battery “. The M8
screws must be very well tightened.
On XTM range, you can insert , if required, a fuse directly on the positive connection to the battery
following the below procedure.
4.5.3
Fuse mounting on battery positive pole (XTM only)
A fuse delivered with the unit (XTM) can be mounted directly on the positive connecting pole to
the battery respecting the below stacking order.
The presence of this fuse does not exempt an installation of a protective device (fuse or circuit
breaker) as close as possible of the battery.
Be careful with the orientation of the ceramic washer. There is a small lip on one side
which must fit into the cable lug’s hole.
4.5.4
Battery-side connection
Before connecting the battery, carefully check the voltage and polarity of the battery
using a voltmeter.
Incorrect polarity or surge voltage may seriously damage the device.
Prepare the batteries for connection: appropriate battery clamps, protection device (f), cable in
good conditions with correctly fitted clamps.
Fasten the negative cable on to the negative pole (-) of the battery and the positive cable on the
open protection device (f).
When connecting the battery, a spark may occur when connecting the second pole.
This spark is normal and due to the load of the internal filtering capacity of the Xtender
even if the unit is halted by the main on off command (1).
