Power supply

The power supply from the main must be sufficiently powerful and constant to ensure that the machine can be operated without problem.

Fuses

The power outlet must be correctly fused in accordance with the electric motor, the length of the power cable and the area of the power cable’s conductor. The table “Guide values for mains connection” in the “Technical data” section shows which fuse is required for the electric motor. The machine is equipped with Softstart which reduces the starting peaks and can be started with most types of fuses. If a fuse keeps blowing, there is a fault in the electrical system or in the machine that is connected to it. Before restarting the machine the source of the fault must be removed.

Power cable

The machine is connected to the mains with a 3 phase power cable. It is very important that the cable that is used is correctly dimensioned, i.e. that it has the correct cross- sectional area in relation to the length of the conductor in order to counteract drops in voltage. The guide values for the cable’s size are set out in the table “Guide values for mains connection” in the “Technical data” section.

Generator usage

Length of cable and specification of generator needs to be considered when choosing generator size. Check for power supply, always as close to the machine as possible. There’s many type of generators on the market, always test compatibility with your DXR.

Generator DXR
	(1) Start current (Amp)	(2) Rated current (Amp @ V)
Machine		50 Hz	60 Hz
DXR 140	75	27 A @ 400 V	24 A @ 460 V
