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.
– Switch off the engines and switch off the ignition of both vehicles.
– Switch off the battery main switch on the ROPA machine, wait for 6 minutes.
Check that the battery disconnector relay has really opened (green LED on the R-
Touch is off if ignition is switch 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 place (e.g. grounding strip or engine block) of the assist-
ing vehicle may be connected to a similar place (grounding strip, engine block or
towing lug on the frame pipe at the rear) on the disabled 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 engine of the assisting vehicle and rev this engine up to a medium speed.
– Start the engine of the ROPA machine and make sure, that a start attempt does
not last longer than 15 seconds.
– Before removing the jump start cable, in any case shut off the engine of the assist-
ing vehicle, because 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).
