Guide values for mains connection

The power cable must be dimensioned by a qualified person in accordance with national and local regulations. The
mains socket to which the machine is connected must be dimensioned for the same amperage as the machine's
electrical socket and extension cable, e.g. a 63 A electrical socket must be preceded by a 63 A fuse.

*The cable lenght is calculated with respect to a voltage drop of 20 V during operation. Type of power source and wiring
from power source to power outlet affects possible cable length.

The hydraulic system pressure

Type of pressure
Pump pressure
The pressure in the pipes between pump and main
stop valve. The pressure varies between standby
pressure and max. pressure depending on which
hydraulic functions are being used.
Pressure cutter (DXR310)
Functions equipped with pressure cut-off can never
be run at a higher pressure than that indicated. The
following functions are equipped with pressure cut-
off for the respective pressure level.
Standby pressure*
* The pressure that the pump delivers when no function is activated and the circulation valve is shut.
** Arm pressure is limited to 2176/150 PSI/bar when operating the steel shears.
