4.60.1 Electrical system: Description
The electrical system of the SP 2800 D is
supplied with 24V of power by two 12V
batteries connected in series.
The following should be observed in terms of
jump-starting and welding due to the spatial
separation of both batteries (one on the right
and one on the left side).
4.60.2 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 jumper cable should be made of high-
quality copper cables according to DIN 72553-
25 and have a cross section of min. 35 qmm.
The positive terminal of the machine engine
battery (-G12 right-hand side) and positive
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
cause the alternator to be destroyed.
If the diesel engine of the SP has started, the
cables can be removed again in the reverse
order.
4.60.3 Welding:
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
covered.
The earth terminal of the welding device should
be connected directly to the part being welded.
The housing of the electronic components (e.g.
control parts) and electronic cables must not
come into contact with the welding electrode or
earth terminal of the welding device.
The earth terminal of the welding device may
not be connected to the motor.
Do not conduct welding work on the motor!
4.60.4 Electrical safeguarding of Schwing
components
Depending on the type of machine, the system
can be secured in several places:
- A main safety fuse near the starter battery.
