ELECTRIC SYSTEM

General

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

High-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.

Power supply

The power supply from the main must be sufÞciently 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.

Fuses

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.

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 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.

Low-voltage circuit

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 reÞlling pump.
