Hella Jumbo 320 Xenon - Manual (Page 12)

Mount the relay, protected from spray
water, with connecting terminals
downwards.
Use only the accompanying special
cable set for the electrical connection.
First loosen the ground wire from
the battery; thereafter, make the
electrical connections in
accordance with the wiring diagram.
According to wiring diagram I the
auxiliary headlamps are switched on
together with the existing high-beam
headlamps.
According to wiring diagram II the
auxiliary headlamps are switched on
by means of a separate switch as an
addition to the existing high-beam
headlamps.
Connect the ground wire (-) of the
battery again. Check the lighting
system, align the headlamps, tighten
the screws and firmly fasten the
connecting cables.
If the cable set is lengthened, it
must be ensured that the cable
cross-section is adequate.
The cable lengths between the
ballast and the battery may not
exceed, at 12 V (9 m for 2,5 mm
2
and 5.5 m for 1.5 mm 2 ) and
at 24 V (18 m at 2.5 mm 2
and 11 m at 1.5 mm 2 ).

Security warnings
Before changing lamps, always switch
off the headlamps and isolate them
from the supply voltage.
IMPORTANT!
The ballast must never be
operated without a lamp,
because this can result in
dangerous voltage flashovers
at the plug, which can cause
damage.
Allow the lamp to cool first.
When changing lamps, use protective
eyewear and safety hand-gloves.
The glass body of the Xenon lamp is
filled with different gases and metal
vapors and is under pressure
(danger of bursting).
Never touch the glass bulb of the
Xenon lamp, grip the lamp only at the
base. Carefully remove fingerprints on
the glass bulb with a clean cloth and
alcohol.
Use the lamp only in closed
headlamps. If a Xenon lamp bursts or breaks in
a closed room (workshop), the room
must be cleared for 20 minutes and
ventilated, in order to eliminate any
health hazard from the poisonous
gases.
Xenon lamps are special waste and
must be disposed of properly. If the
lamp is faulty, but the glass bulb is
still intact, it must be disposed of
as special waste, since the
gas/metal vapor mixture contains
mercury and is hence poisonous if
inhaled. If the glass bulb is
destroyed, e.g. owing to an
accident, the Xenon lamp can be
disposed of in the normal trash,
since the mercury would have
evaporated.
