Husqvarna DXR-310 Manual Do Utilizador

The electric system consists of a high-voltage circuit 
and a low-voltage circuit.

High-voltage is used as a power source for both the 
electric motor and the low-voltage circuit. An automat-
ic phase rotation change-over switch ensures that the 
electric motor has the correct rotation direction. 

The power supply from the main must be suffi ciently 
powerful and constant to ensure that the electric mo-
tor runs without problems.

Too high or too low voltage causes the electric mo-
tor’s power consumption, and consequently also its 
temperature, to increase until the motor’s safety circuit 
trips.

The fuses in the distribution box protect the electrical 
system in conjunction with overloading or breakdown. 
The power outlet must be correctly fused with respect 
to 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 “Techni-
cal data” section shows which fuse is required for the 
electric motor.

The machine is equipped with Softstart and can be 
started with most types of fuses.

If a fuse keeps blowing there is a fault in the electri-
cal system or in the machine that is connected to it. 
Before restarting the machine the source of the fault 
must be removed.

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 cor-
rect 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 main connection” in the ’Technical 
data” section.

The high-voltage current is reduced to low-voltage in 
an AC/DC module. It is used to supply power to the 
control system and functions such as work lighting 
and refi lling pump.
