4.18.1 Electrical system: Description
The electric system of the SP 1800 D / SP 3800 D is powered by two 12V batteries
connected in series with 24V.
The following should be observed in terms of jump-starting and welding due to the
spatial separation of both batteries (one on the right-hand and one on the left-hand
side).
4.18.1.1 Jump starting
A diesel engine uses considerably more power to start than a gasoline engine,
which must be considered in the selection of the dispenser unit.
The jump lead should be made of high-quality copper cable in accordance with DIN
72553-25 and have a cross section of min. 35 mm².
The positive terminal of the machine engine battery (-G12 right-hand side) and pos-
itive terminal of the dispenser unit are connected with the red cable.
First, the black cable is attached to the negative terminal of the donor unit and then
to the negative terminal of the machine battery (-G13 on the left-hand side).
Make sure to observe the correct order!
Under no circumstances may the terminals of the batteries be connected the other
way round.
The two batteries of the SP must remain connected electrically; an interruption can
lead to the destruction of the alternator.
If the diesel engine of the SP has started, the cables can be removed again in the
reverse order.
4.18.1.2 Welding
ACHTUNG!
Attention!
Welding work on the frame may only be carried out by qualified personnel!
Do not conduct welding work on the motor!
In order to protect the electronic components from surges during electric welding
work, the following safety measures must be observed:
• Positive terminal (on the battery -G12 right-hand side) and minus terminals (on
the battery -G13 left-hand side) should be removed from the batteries and cov-
ered.
