DSR PROBOOSTER DSR103 Manuel D'utilisation page 9

A. For a negative-grounded vehicle,
connect the POSITIVE (RED) clip
from the booster to the POSITIVE
(POS, P, +) ungrounded post of the
battery. Connect the NEGATIVE
(BLUE) clip to the vehicle chassis
or engine block away from the
battery. Do not connect the clip
to the carburetor, fuel lines or
sheet-metal body parts. Connect
to a heavy gauge metal part of the
frame or engine block.
B. For a positive-grounded
vehicle, connect the NEGATIVE
(BLUE) clip from the booster
to the NEGATIVE (NEG, N, -)
ungrounded post of the battery.
Connect the POSITIVE (RED) clip
to the vehicle chassis or engine
block away from the battery.
Do not connect the clip to the
carburetor, fuel lines or sheet-
metal body parts. Connect to a
heavy gauge metal part of the
frame or engine block.
7. Connect the output voltage selector.
12V
8. Crank the engine. If the engine does not
start within 8-10 seconds, stop cranking
and wait at least 3 minutes before
attempting to start the vehicle again.
• To allow the voltage of the booster
battery to build up again.
• To allow the renewal of gases inside
the battery.
• To allow the internal components of
the battery to cool down.
If you do not wait and/or the starting
attempt is too long, you risk losing power,
you reduce your starting possibilities by
the second attempt and you risk melting
the fuse inside.
IMPORTANT:
• Never connect the booster to a battery
or starter which is in short-circuit. The
internal fuse will blow.
• Make sure clamps are connected
correctly.
• Never disconnect the booster while
engine running when there is no
battery in the vehicle or when the
24V
• 9 •
vehicle's battery is at 0 volt. This may
damage the alternator.
9. After the engine starts, disconnect
the output voltage selector.
Then, disconnect the blue clamp (-)
and the red clamp, (+) in that order.
10. Return the cables and clamps to their
support posts.
11. Immediately recharge the booster.
8.5 Indication of polarity inversion
If the polarity is incorrect, the alarm will sound:
• If the remaining voltage in the batteries
of the vehicle is at least 4 volts
• If the output voltage selector is not
connected
8.6 Internal fuse replacement
The booster is equipped with an internal
fuse. It can melt following a short circuit or
a too-long start attempt.
To monitor the fuse:
• Push the button. If the blue LED under
the fuse does not light up, the fuse is
melted.
Fuse specification
AMG Heavy Duty 500A
WARNING! KEEP AWAY FROM SPARKS
AND FLAMES – BATTERY COULD EMIT
EXPLOSIVE GASES.
1. Allow the fuse to cool down
completely (approximately 5 minutes).
2. Make sure the unit is unplugged from
the external charger.
3. Using a wrench, remove the first nut
securing the fuse. Repeat the same
step for the second nut. Remove the
open fuse and replace it with a new
one of the same type and rating.
4. Tighten the nuts to secure the fuse.
5. The unit is now ready to use.
8.7 Use of Auxiliary DC Cables
(DSR103AUX Only)
The booster is equipped with an auxiliary
DC cable connection. This connection is
only to be used with DSR Auxiliary DC
Cables.
IMPORTANT: Using the booster without a
battery installed in the vehicle will damage
the vehicle's electrical system.
IMPORTANT: Do not use the booster
while charging its internal battery.
IMPORTANT: Do not use the built-in
DC cables of the jump starter and the
auxiliary DC cable at the same time.
