Jump starting and charging the battery
Jump starting
Because, in the past, damage has been caused several times due to improper charg-
ing of batteries or jump starting, we would like to expressly point out that machine may
only be jump started using the following method.
(3) Battery disconnect relay
– Exclusively use standardized jump starting cables with actually sufficient cross sec-
tion of the electrical conductors.
– Only use batteries with the same rated voltage (24V).
– Make sure of sufficient battery capacity of the assisting vehicle.
– Shut down the combustion engines and switch off the ignition of both vehicles.
– Switch off the battery main switch See Page 334 on the ROPA machine. Check
that the battery disconnector relay has really opened (green LED on the R-Touch is
off if ignition is switched ON).
– Make sure that the two vehicles do not touch at any point.
– First connect the negative terminal of the battery of the assisting vehicle to the neg-
ative terminal of the battery of the ROPA machine. Alternatively, a blank metallic
and electrically conductive spot (e.g. grounding strip or engine block) of the assist-
ing vehicle may be connected to a similar place (grounding strip, engine block or
salvaging lug on the main frame at the rear) of the ROPA machine.
– Connect the positive terminal of the battery of the assisting vehicle to the positive
terminal of ROPA machine.
– Switch on the battery main switch on the ROPA machine.
– Start the combustion engine of the assisting vehicle and rev it up to a medium
speed.
– Start the diesel engine of the ROPA machine and make sure, that the start attempt
does not last longer than 15 seconds.
– Before removing the jump start cable, in any case shut down the combustion
engine of the assisting vehicle. Otherwise, the electronic system of the assisting
vehicle may be damaged.
– Remove the jump start cable from both vehicles in reverse order (first remove the
positive cable, then the negative cable).
